  Target Milestone: ---

Since r12-2424, I've noticed new failures in hwasan tests on aarch64 (I'm
testing a cross-compiler using QEMU, but it seems the same failures are
reported by native testers on gcc-testresults)

The patch seems to have enabled many new tests, some of which fail:

x86 also get 2 new failures
```
FAIL: c-c++-common/hwasan/alloca-gets-different-tag.c   -O2 -flto
-fuse-linker-plugin -fno-fat-lto-objects  execution test
FAIL: c-c++-common/hwasan/alloca-outside-caught.c   -O2 -flto
-fuse-linker-plugin -fno-fat-lto-objects  output pattern test
``` 

And failure is because pointer passes to __hwasan_tag_memory is supposed to be
untagged(it will call TagMemoryAligned and then call MemToShadow where it shift
the address w/ kShadowScale(here is 4).

inline uptr MemToShadow(uptr untagged_addr) {
  return (untagged_addr >> kShadowScale) + GetShadowOffset();
}

And for local arrays which need to be tagged, pointer passed to
__hwasan_tag_memory is rsp+offset where rsp is not tagged, and this should be
ok, but sometimes gcc will do optimization to convert rsp+offset to rbp+offset,
but rbp is tagged, then it will raise an exception of  SGEV SGEV for illegal
address.

What can you see for a vanilla GCC compiler?

hwasan is not enabled by x86 on the trunk which means there must be no impact
for a vanilla x86 GCC compiler.

--- Comment #7 from Matthew Malcomson <matmal01 at gcc dot gnu.org> ---
Hi there,

I didn't check all the new tests that Christophe mentioned, but all those I
checked had `dg-require-effective-target hwaddress_exec` in them.

The test that determines that effective target should only pass with a modern
enough kernel (one that supports passing tagged pointers to its syscalls).
It is still failing on my native AArch64 machine.

For anyone that is seeing them -- what kernel version are you running?
If your kernel has not changed could you manually run the check and see if it
passes and why?

I've unfortunately lost my testing environment.  I'm working on getting it back
but will be a while before I can see if I can reproduce the failures on a
machine with the required kernel.

I think this is fixed.
