Subject: [PATCH 01/84] tcg: Include "qemu/timer.h" for profile_getclock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When CONFIG_PROFILER is set there are various undefined references to
profile_getclock. Include the header which defines this function.
For example:
../tcg/tcg.c: In function ‘tcg_gen_code’:
../tcg/tcg.c:4905:51: warning: implicit declaration of function ‘profile_getclock’ [-Wimplicit-function-declaration]
4905 | qatomic_set(&prof->opt_time, prof->opt_time - profile_getclock());

Subject: [PATCH 02/84] tcg: Link branches to the labels
This allows us to easily find all branches that use a label.
Since 'refs' is only tested vs zero, remove it and test for
an empty list instead. Drop the use of bitfields, which had
been used to pack refs into a single 32-bit word.

While changes are made to prot within tlb_set_page_full, they are
an implementation detail of softmmu. Retain the original for any
target use of probe_access_full.

Subject: [PATCH 06/84] accel/tcg: Honor TLB_DISCARD_WRITE in atomic_mmu_lookup
Using an atomic write or read-write insn on ROM is basically
a happens-never case. Handle it via stop-the-world, which
will generate non-atomic serial code, where we can correctly
ignore the write while producing the correct read result.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit
Atomic operations are read-modify-write, and we'd like to
be able to test both read and write with one call. This is
easy enough, with BP_MEM_READ | BP_MEM_WRITE.
Add BP_HIT_SHIFT to make it easy to set BP_WATCHPOINT_HIT_*.

Since one of the two has been using the mnemonic, assume that the
comment about "older versions of the assember" is obsolete, as even
that is 4 years old.

Subject: [PATCH 12/84] tcg: Remove tcg_check_temp_count, tcg_clear_temp_count
Since all temps allocated by guest front-ends are now TEMP_TB,
and we don't recycle TEMP_TB, there's no point in requiring
that the front-ends free the temps at all. Begin by dropping
the inner-most checks that all temps have been freed.

Subject: [PATCH 18/84] target/arm: Drop DisasContext.tmp_a64
Translators are no longer required to free tcg temporaries,
therefore there's no need to record temps for later freeing.

Subject: [PATCH 20/84] target/arm: Drop new_tmp_a64_zero
Only the use within cpu_reg requires a writable temp,
so inline new_tmp_a64_zero there. All other uses are
fine with a constant temp, so use tcg_constant_i64(0).

Subject: [PATCH 41/84] target/loongarch: Drop temp_new
Translators are no longer required to free tcg temporaries,
therefore there's no need to record temps for later freeing.
Replace the few uses with tcg_temp_new.

Subject: [PATCH 50/84] target/riscv: Drop ftemp_new
Translators are no longer required to free tcg temporaries,
therefore there's no need to record temps for later freeing.
Replace the few uses with tcg_temp_new_i64.

Subject: [PATCH 55/84] target/sparc: Drop get_temp_tl
Translators are no longer required to free tcg temporaries,
therefore there's no need to record temps for later freeing.
Replace the few uses with tcg_temp_new.

Subject: [PATCH 58/84] target/sparc: Drop free_compare
Translators are no longer required to free tcg temporaries.
Remove the g1 and g2 members of DisasCompare, as they were
used to track which temps needed to be freed.

Subject: [PATCH 60/84] target/xtensa: Drop reset_sar_tracker
Translators are no longer required to free tcg temporaries.
Remove sar_m32_allocated, as sar_m32 non-null is equivalent.

Subject: [PATCH 79/84] target/xtensa: Tidy translate_bb
Replace ifdefs with C, tcg_const_i32 with tcg_constant_i32.
We only need a single temporary for this.
