Richard Henderson 1f51573f79 target/arm: Fix SME full tile indexing
For the outer product set of insns, which take an entire matrix
tile as output, the argument is not a combined tile+column.
Therefore using get_tile_rowcol was incorrect, as we extracted
the tile number from itself.

The test case relies only on assembler support for SME, since
no release of GCC recognizes -march=armv9-a+sme yet.

Peter Maydell 3dc2afeab2 tests/tcg/aarch64/sysregs.c: Use S syntax for id_aa64zfr0_el1 and id_aa64smfr0_el1
Some assemblers will complain about attempts to access
id_aa64zfr0_el1 and id_aa64smfr0_el1 by name if the test
binary isn't built for the right processor type:

 /tmp/ccASXpLo.s:782: Error: selected processor does not support system register name 'id_aa64zfr0_el1'
 /tmp/ccASXpLo.s:829: Error: selected processor does not support system register name 'id_aa64smfr0_el1'

However, these registers are in the ID space and are guaranteed to
read-as-zero on older CPUs, so the access is both safe and sensible.
Switch to using the S syntax, as we already do for ID_AA64ISAR2_EL1
and ID_AA64MMFR2_EL1.  This allows us to drop the HAS_ARMV9_SME check
and the makefile machinery to adjust the CFLAGS for this test, so we
don't rely on having a sufficiently new compiler to be able to check
these registers.

This means we're actually testing the SME ID register: no released
GCC yet recognizes -march=armv9-a+sme, so that was always skipped.
It also avoids a future problem if we try to switch the "do we have
SME support in the toolchain" check from "in the compiler" to "in the
assembler" (at which point we would otherwise run into the above
errors).

Alex Bennée 6d03226b42 plugins: force slow path when plugins instrument memory ops
The lack of SVE memory instrumentation has been an omission in plugin
handling since it was introduced. Fortunately we can utilise the
probe_* functions to force all all memory access to follow the slow
path. We do this by checking the access type and presence of plugin
memory callbacks and if set return the TLB_MMIO flag.

We have to jump through a few hoops in user mode to re-use the flag
but it was the desired effect:

 ./qemu-system-aarch64 -display none -serial mon:stdio \
   -M virt -cpu max -semihosting-config enable=on \
   -kernel ./tests/tcg/aarch64-softmmu/memory-sve \
   -plugin ./contrib/plugins/libexeclog.so,ifilter=st1w,afilter=0x40001808 -d plugin

gives (disas doesn't currently understand st1w):

  0, 0x40001808, 0xe54342a0, ".byte 0xa0, 0x42, 0x43, 0xe5", store, 0x40213010, RAM, store, 0x40213014, RAM, store, 0x40213018, RAM

And for user-mode:

  ./qemu-aarch64 \
    -plugin contrib/plugins/libexeclog.so,afilter=0x4007c0 \
    -d plugin \
    ./tests/tcg/aarch64-linux-user/sha512-sve

gives:

Alex Bennée af323aabe2 tests/tcg: add mechanism to handle plugin arguments
We recently missed a regression that should have been picked up by
check-tcg. This was because the libmem plugin is effectively a NOP if
the user doesn't specify the type to use.

Rather than changing the default behaviour add an additional expansion
so we can take this into account in future.

Thomas Huth e31f08dc74 pc-bios/s390-ccw: Move the stack array into start.S
The stack array is only referenced from the start-up code (which is
shared between the s390-ccw.img and the s390-netboot.img), but it is
currently declared twice, once in main.c and once in netmain.c.
It makes more sense to declare this in start.S instead - which will
also be helpful in the next patch, since we need to mention the .bss
section in start.S in that patch.

While we're at it, let's also drop the huge alignment of the stack,
since there is no technical requirement for aligning it to page
boundaries.

Richard Henderson ea185a557b tests/plugin: Remove duplicate insn log from libinsn.so
This is a perfectly natural occurrence for x86 "rep movb",
where the "rep" prefix forms a counted loop of the one insn.

During the tests/tcg/multiarch/memory test, this logging is
triggered over 350000 times.  Within the context of cross-i386-tci
build, which is already slow by nature, the logging is sufficient
to push the test into timeout.

Marco Liebel 3fd49e2217 Hexagon (target/hexagon) Fix assignment to tmp registers
The order in which instructions are generated by gen_insn() influences
assignment to tmp registers. During generation, tmp instructions (e.g.
generate_V6_vassign_tmp) use vreg_src_off() to determine what kind of
register to use as source. If some instruction (e.g.
generate_V6_vmpyowh_64_acc) uses a tmp register but is generated prior
to the corresponding tmp instruction, the vregs_updated_tmp bit map
isn't updated in time.

Exmple:
    { v14.tmp = v16; v25 = v14 } This works properly because
    generate_V6_vassign_tmp is generated before generate_V6_vassign
    and the bit map is updated.

    { v15:14.tmp = vcombine(v21, v16); v25:24 += vmpyo(v18.w,v14.h) }
    This does not work properly because vmpyo is generated before
    vcombine and therefore the bit map does not yet know that there's
    a tmp register.

The parentheses in the decoding function were in the wrong place.
Moving them to the correct location makes shuffling of .tmp vector
registers work as expected.

Matheus Tavares Bernardino dae66a3f66 gdbstub: add test for untimely stop-reply packets
In the previous commit, we modified gdbstub.c to only send stop-reply
packets as a response to GDB commands that accept it. Now, let's add a
test for this intended behavior. Running this test before the fix from
the previous commit fails as QEMU sends a stop-reply packet
asynchronously, when GDB was in fact waiting an ACK.

both vector registers are the same. Using vshuff in this way is

Matheus Tavares Bernardino 14edcf11e2 Hexagon (decode): look for pkts with multiple insns at the same slot
Each slot in a packet can be assigned to at most one instruction.
Although the assembler generally ought to enforce this rule, we better
be safe than sorry and also do some check to properly throw an "invalid
packet" exception on wrong slot assignments.

This should also make it easier to debug possible future errors caused
by missing updates to `find_iclass_slots()` rules in
target/hexagon/iclass.c.

Taylor Simpson 163e5fa38e Hexagon (target/hexagon) Additional instructions handled by idef-parser
**** Changes in v3 ****
Fix bugs exposed by dpmpyss_rnd_s0 instruction
    Set correct size/signedness for constants
    Test cases added to tests/tcg/hexagon/misc.c

**** Changes in v2 ****
Fix bug in imm_print identified in clang build

Currently, idef-parser skips all floating point instructions.  However,
there are some floating point instructions that can be handled.

The following instructions are now parsed
    F2_sfimm_p
    F2_sfimm_n
    F2_dfimm_p
    F2_dfimm_n
    F2_dfmpyll
    F2_dfmpylh

To make these instructions work, we fix some bugs in parser-helpers.c
    gen_rvalue_extend
    gen_cast_op
    imm_print
    lexer properly sets size/signedness of constants

Test cases added to tests/tcg/hexagon/fpstuff.c

The following have overrides
    S2_insert
    S2_insert_rp
    S2_asr_r_svw_trun

These instructions have semantics that write to the destination
before all the operand reads have been completed.  Therefore,
the idef-parser versions were disabled with the short-circuit patch.

Taylor Simpson d05d5eebc7 Hexagon (target/hexagon) Short-circuit more HVX single instruction packets
The generated helpers for HVX use pass-by-reference, so they can't
short-circuit when the reads/writes overlap.  The instructions with
overrides are OK because they use tcg_gen_gvec_*.

We add a flag has_hvx_helper to DisasContext and extend gen_analyze_funcs
to set the flag when the instruction is an HVX instruction with a
generated helper.

We add an override for V6_vcombine so that it can be short-circuited
along with a test case in tests/tcg/hexagon/hvx_misc.c

not really improving coverage that much. Restrict the plugin tests to
just the MULTIARCH_TESTS which are shared between most architecture
for both system and user-mode. For those that aren't we need to squash

Alex Bennée bcbc36a98f testing: probe gdb for supported architectures ahead of time
Currently when we encounter a gdb that is old or not built with
multiarch in mind we fail rather messily. Try and improve the
situation by probing ahead of time and setting
HOST_GDB_SUPPORTS_ARCH=y in the relevant tcg configs. We can then skip
and give a more meaningful message if we don't run the test.

The F2_sffms instruction [r0 -= sfmpy(r1, r2)] doesn't properly
handle -0.  Previously we would negate the input operand by subtracting
from zero.  Instead, we negate by changing the sign bit.

Bastian Koppelmann 3c471b0701 tests/docker: Use binaries for debian-tricore-cross
since binutils is pretty old, it fails our CI repeatedly during the
compilation of tricore-binutils. We created a precompiled version using
the debian docker image and download it instead of building it ourself.

We also updated the package to include a newer version of binutils, gcc,
and newlib. The default TriCore ISA version used by tricore-as changed
from the old version, so we have to specify it now. If we don't
'test_fadd' fails with 'unknown opcode'.

The new assembler also picks a new encoding in ld.h which fails the
'test_ld_h' test. We fix that by using the newest TriCore CPU for QEMU.

The old assembler accepted an extra ')' in 'test_imask'. The new one
does not, so lets remove it.

The code currently uses -nostartfiles, but this does not prevent
linking with libc. On Fedora there is no cross-libc, so the linking
step fails.

Fix by using the more comprehensive -nostdlib (that's also what
probe_target_compiler() checks for as well).

Paolo Bonzini 60c7dd22e1 target/i386: fix ADOX followed by ADCX
When ADCX is followed by ADOX or vice versa, the second instruction's
carry comes from EFLAGS and the condition codes use the CC_OP_ADCOX
operation.  Retrieving the carry from EFLAGS is handled by this bit
of gen_ADCOX:

        tcg_gen_extract_tl(carry_in, cpu_cc_src,
            ctz32(cc_op == CC_OP_ADCX ? CC_C : CC_O), 1);

Unfortunately, in this case cc_op has been overwritten by the previous
"if" statement to CC_OP_ADCOX.  This works by chance when the first
instruction is ADCX; however, if the first instruction is ADOX,
ADCX will incorrectly take its carry from OF instead of CF.

Fix by moving the computation of the new cc_op at the end of the function.
The included exhaustive test case fails without this patch and passes
afterwards.

Because ADCX/ADOX need not be invoked through the VEX prefix, this
regression bisects to commit 16fc5726a6 ("target/i386: reimplement
0x0f 0x38, add AVX", 2022-10-18).  However, the mistake happened a
little earlier, when BMI instructions were rewritten using the new
decoder framework.

Mukilan Thiyagarajan eaee3b6faf tests/tcg/hexagon: fix underspecifed asm constraints
There are two test cases where the inline asm doesn't
have the correct constraints causing them to fail.

In misc.c, the 'result' output needs the early clobber
modifier since the rest of the inputs are read after
assignment to the output register.

In mem_noshuf.c, the register r7 is written to but
not specified in the clobber list.

Mukilan Thiyagarajan c979d901c8 linux-user/hexagon: fix signal context save & restore
This patch fixes the issue originally reported in
this thread:

https://lists.gnu.org/archive/html/qemu-devel/2021-11/msg01102.html

The root cause of the issue is a bug in the hexagon specific
logic for saving & restoring context during signal delivery.
The CPU state has two different representations for the
predicate registers. The current logic saves & restores only
the aliased HEX_REG_P3_O register, which is part of env->gpr[]
field in the CPU state, but not the individual byte-level
predicate registers (pO, p1, p2, p3) backed by env->pred[].

Since all predicated instructions refer only to the
indiviual registers, switching to and back from a signal handler
can clobber these registers if the signal handler writes to them
causing the normal application code to behave unpredictably when
context is restored.

In the reported issue with the 'signals' test, since the updated
hexagon toolchain had built musl with -O2, the functions called
from non_trivial_free were inlined. This meant that the code
emitted reused predicate P0 computed in the entry translation
block of the function non_trivial_free in one of the child TB
as part of an assertion. Since P0 is clobbered by the signal
handler in the signals test, the assertion in non_trivial_free
fails incorectly. Since musl for hexagon implements the 'abort'
function by deliberately writing to memory via null pointer,
this causes the test to fail with segmentation fault.

This patch modifies the signal context save & restore logic
to include the individual p0, p1, p2, p3 and excludes the
32b p3_0 register since its value is derived from the former
registers. It also adds a new test case that reliabily
reproduces the issue for all four predicate registers.

Zhuojia Shen bc6bd20ee3 target/arm: align exposed ID registers with Linux
In CPUID registers exposed to userspace, some registers were missing
and some fields were not exposed.  This patch aligns exposed ID
registers and their fields with what the upstream kernel currently
exposes.

Specifically, the following new ID registers/fields are exposed to
userspace:

ID_AA64PFR1_EL1.BT:       bits 3-0
ID_AA64PFR1_EL1.MTE:      bits 11-8

ID_AA64ZFR0_EL1.SHA3:     bits 35-32
ID_AA64ZFR0_EL1.SM4:      bits 43-40
ID_AA64ZFR0_EL1.I8MM:     bits 47-44
ID_AA64ZFR0_EL1.F32MM:    bits 55-52
ID_AA64ZFR0_EL1.F64MM:    bits 59-56

ID_AA64SMFR0_EL1.F32F32:  bit 32
ID_AA64SMFR0_EL1.B16F32:  bit 34
ID_AA64SMFR0_EL1.F16F32:  bit 35
ID_AA64SMFR0_EL1.I8I32:   bits 39-36
ID_AA64SMFR0_EL1.F64F64:  bit 48
ID_AA64SMFR0_EL1.I16I64:  bits 55-52
ID_AA64SMFR0_EL1.FA64:    bit 63

ID_AA64MMFR0_EL1.ECV:     bits 63-60

ID_AA64MMFR1_EL1.AFP:     bits 47-44

ID_AA64MMFR2_EL1.AT:      bits 35-32

ID_AA64ISAR0_EL1.RNDR:    bits 63-60

ID_AA64ISAR1_EL1.FRINTTS: bits 35-32

ID_AA64ISAR2_EL1.GPA3:    bits 11-8
ID_AA64ISAR2_EL1.APA3:    bits 15-12

The code is also refactored to use symbolic names for ID register fields
for better readability and maintainability.

The test case in tests/tcg/aarch64/sysregs.c is also updated to match
the intended behavior.

Taylor Simpson 83853ea0ef Hexagon (target/hexagon) Fix predicated assignment to .tmp and .cur
Here are example instructions with a predicated .tmp/.cur assignment
    if (p1) v12.tmp = vmem(r7 + #0)
    if (p0) v12.cur = vmem(r9 + #0)
The .tmp/.cur indicates that references to v12 in the same packet
take the result of the load.  However, when the predicate is false,
the value at the start of the packet should be used.  After the packet
commits, the .tmp value is dropped, but the .cur value is maintained.

To fix this bug, we preload the original value from the HVX register
into the temporary used for the result.

Test cases added to tests/tcg/hexagon/hvx_misc.c

Tweak the semantic patch to drop redundant parenthesis around the
return expression.

Coccinelle drops a comment in hw/rdma/vmw/pvrdma_cmd.c; restored
manually.

Coccinelle messes up vmdk_co_create(), not sure why.  Change dropped,
will be done manually in the next commit.

Line breaks in target/avr/cpu.h and hw/rdma/vmw/pvrdma_cmd.c tidied up

Whitespace in tools/virtiofsd/fuse_lowlevel.c tidied up manually.

checkpatch.pl complains "return of an errno should typically be -ve"
two times for hw/9pfs/9p-synth.c.  Preexisting, the patch merely makes
it visible to checkpatch.pl.

Paolo Bonzini d1bb978ba1 target/i386: fix cmpxchg with 32-bit register destination
Unlike the memory case, where "the destination operand receives a write
cycle without regard to the result of the comparison", rm must not be
touched altogether if the write fails, including not zero-extending
it on 64-bit processors.  This is not how the movcond currently works,
because it is always followed by a gen_op_mov_reg_v to rm.

To fix it, introduce a new function that is similar to gen_op_mov_reg_v
but writes to a TCG temporary.

Considering that gen_extu(ot, oldv) is not needed in the memory case
either, the two cases for register and memory destinations are different
enough that one might as well fuse the two "if (mod == 3)" into one.
So do that too.

Paolo Bonzini 2872b0f390 target/i386: implement FMA instructions
The only issue with FMA instructions is that there are _a lot_ of them (30
opcodes, each of which comes in up to 4 versions depending on VEX.W and
VEX.L; a total of 96 possibilities).  However, they can be implement with
only 6 helpers, two for scalar operations and four for packed operations.
(Scalar versions do not do any merging; they only affect the bottom 32
or 64 bits of the output operand.  Therefore, there is no separate XMM
and YMM of the scalar helpers).

First, we can reduce the number of helpers to one third by passing four
operands (one output and three inputs); the reordering of which operands
go to the multiply and which go to the add is done in emit.c.

Second, the different instructions also dispatch to the same softfloat
function, so the flags for float32_muladd and float64_muladd are passed
in the helper as int arguments, with a little extra complication to
handle FMADDSUB and FMSUBADD.

Paolo Bonzini cf5ec6641e target/i386: implement F16C instructions
F16C only consists of two instructions, which are a bit peculiar
nevertheless.

First, they access only the low half of an YMM or XMM register for the
packed-half operand; the exact size still depends on the VEX.L flag.
This is similar to the existing avx_movx flag, but not exactly because
avx_movx is hardcoded to affect operand 2.  To this end I added a "ph"
format name; it's possible to reuse this approach for the VPMOVSX and
VPMOVZX instructions, though that would also require adding two more
formats for the low-quarter and low-eighth of an operand.

Second, VCVTPS2PH is somewhat weird because it *stores* the result of
the instruction into memory rather than loading it.

If needed, a common library can be introduced later.

While at it, for consistency move all the -cpu max rules to the
same place.

Richard Henderson 00c07344fa target/riscv: Make translator stop before the end of a page
Right now the translator stops right *after* the end of a page, which
breaks reporting of fault locations when the last instruction of a
multi-insn translation block crosses a page boundary.

Ilya Leoshkevich 950936681f target/i386: Make translator stop before the end of a page
Right now translator stops right *after* the end of a page, which
breaks reporting of fault locations when the last instruction of a
multi-insn translation block crosses a page boundary.

An implementation, like the one arm and s390x have, would require an
i386 length disassembler, which is burdensome to maintain. Another
alternative would be to single-step at the end of a guest page, but
this may come with a performance impact.

Fix by snapshotting disassembly state and restoring it after we figure
out we crossed a page boundary. This includes rolling back cc_op
updates and emitted ops.

Taylor Simpson 15fc6badbd Hexagon (target/hexagon) fix bug in mem_noshuf load exception
The semantics of a mem_noshuf packet are that the store effectively
happens before the load.  However, in cases where the load raises an
exception, we cannot simply execute the store first.

This change adds a probe to check that the load will not raise an
exception before executing the store.

If the load is predicated, this requires special handling.  We check
the condition before performing the probe.  Since, we need the EA to
perform the check, we move the GET_EA portion inside CHECK_NOSHUF_PRED.

Call the CHECK_NOSHUF macro multiple times: once in the
fGEN_TCG_PRED_LOAD() and again in fLOAD().

Before this commit, a packet with a store and a predicated
load with mem_noshuf that gets encoded like this:

    { P0 = cmp.eq(R17,#0x0)
      memw(R18+#0x0) = R2
      if (!P0.new) R3 = memw(R17+#0x4) }

... would end up generating a branch over both the load
and the store like so:

    ...
    brcond_i32 loc17,$0x0,eq,$L1
    mov_i32 loc18,store_addr_1
    qemu_st_i32 store_val32_1,store_addr_1,leul,0

Ilya Leoshkevich 23f13e1986 tests/tcg/s390x: test signed vfmin/vfmax
Add a test to prevent regressions. Try all floating point value sizes
and all combinations of floating point value classes. Verify the results
against PoP tables, which are represented as close to the original as
possible - this produces a lot of checkpatch complaints, but it seems
to be justified in this case.

Paolo Bonzini bb52a8a278 tests/tcg: compile system emulation tests as freestanding
System emulation tests do not run in a hosted environment, since they
do not link with libc.  They should only use freestanding headers
(float.h, limits.h, stdarg.h, stddef.h, stdbool.h, stdint.h,
stdalign.h, stdnoreturn.h) and should be compiled with -ffreestanding
in order to use the compiler implementation of those headers
rather than the one in libc.

Some tests are using inttypes.h instead of stdint.h, so fix that.

Richard Henderson b97028b8c5 target/riscv: Set env->bins in gen_exception_illegal
While we set env->bins when unwinding for ILLEGAL_INST,
from e.g. csrrw, we weren't setting it for immediately
illegal instructions.

Add a testcase for mtval via both exception paths.
