Alex Bennée ecbcc9ead2 tests/tcg: add a system test to check memory instrumentation
At first I thought I could compile the user-mode test for system mode
however we already have a fairly comprehensive test case for system
mode in "memory" so lets use that.

As tracking every access will quickly build up with "print-access" we
add a new mode to track groups of reads and writes to regions. Because
the test_data is 16k aligned we can be sure all accesses to it are
ones we can count.

First we extend the test to report where the test_data region is. Then
we expand the pdot() function to track the total number of reads and
writes to the region. We have to add some addition pdot() calls to
take into account multiple reads/writes in the test loops.

Finally we add a python script to integrate the data from the plugin
and the output of the test and validate they both agree on the total
counts. As some boot codes clear the bss we also add a flag to add a
regions worth of writes to the expected total.

Pierrick Bouvier 354b5c19b3 tests/tcg/multiarch: add test for plugin memory access
Add an explicit test to check expected memory values are read/written.
8,16,32 load/store are tested for all arch.
64,128 load/store are tested for aarch64/x64.
atomic operations (8,16,32,64) are tested for x64 only.

By default, atomic accesses are non atomic if a single cpu is running,
so we force creation of a second one by creating a new thread first.

load/store helpers code path can't be triggered easily in user mode (no
softmmu), so we can't test it here.

Output of test-plugin-mem-access.c is the list of expected patterns in
plugin output. By reading stdout, we can compare to plugins output and
have a multiarch test.

Can be run with:
make -C build/tests/tcg/$ARCH-linux-user run-plugin-test-plugin-mem-access-with-libmem.so

Richard Henderson 6c180490b0 tests/tcg: Use --noexecstack with assembler files
Add the --noexecstack assembler command-line option to avoid:

  /usr/bin/ld: warning: boot.o: missing .note.GNU-stack section implies executable stack
  /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker

which is enabled by default with current debian cross toolchains.

Paolo Bonzini 2038f8c877 tests/tcg: move configuration to a sub-shell script
Avoid the repeated inclusions of config-target.mak, which have
risks of namespace pollution, and instead build minimal configuration
files in a configuration script.  The same configuration files can
also be included in Makefile and Makefile.qemu

[AJB 10/09/19]
In the original PR this had inadvertently enabled tests
for ppc64abi32. However as the rest of the multiarch tests work rather
than disabling the otherwise correctly functioning build I've just
skipped the failing linux-test test. For some reason I can't debug it
with TCG so I'm leaving that to the PPC maintainers to look at.

Paolo Bonzini 6a9e0ef32a tests/tcg: use EXTRA_CFLAGS everywhere
For i386 specifically, this allows using the host GCC
to compile the i386 tests.  But, it should really be
done for all targets, unless we want to pass $(EXTRA_CFLAGS)
directly as part of $(CC).

Paolo Bonzini 7d37435bd5 avoid TABs in files that only contain a few
Most files that have TABs only contain a handful of them.  Change
them to spaces so that we don't confuse people.

disas, standard-headers, linux-headers and libdecnumber are imported
from other projects and probably should be exempted from the check.
Outside those, after this patch the following files still contain both
8-space and TAB sequences at the beginning of the line.  Many of them
have a majority of TABs, or were initially committed with all tabs.
