    • i386: Remove _Unwind_Frames_Increment · b72e71a3 
      CET kernel has been changed to place a restore token on shadow stack for
signal handler to enhance security.  It is usually transparent to user
programs since kernel will pop the restore token when signal handler
returns.  But when an exception is thrown from a signal handler, now
we need to remove _Unwind_Frames_Increment to pop the the restore token
from shadow stack.  Otherwise, we get

    • libsanitizer: Mark REAL(swapcontext) with indirect_return attribute on x86 · c83b4b82 
      Cherry-pick compiler-rt revision 337603:

When shadow stack from Intel CET is enabled, the first instruction of all
indirect branch targets must be a special instruction, ENDBR.

lib/asan/asan_interceptors.cc has

...
  int res = REAL(swapcontext)(oucp, ucp);
...

REAL(swapcontext) is a function pointer to swapcontext in libc.  Since
swapcontext may return via indirect branch on x86 when shadow stack is
enabled, as in this case,

int res = REAL(swapcontext)(oucp, ucp);
              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^  This function may be
returned via an indirect branch.

Here compiler must insert ENDBR after call, like

call *bar(%rip)
endbr64

I opened an LLVM bug:

https://bugs.llvm.org/show_bug.cgi?id=38207

to add the indirect_return attribute so that it can be used to inform
compiler to insert ENDBR after REAL(swapcontext) call.  We mark
REAL(swapcontext) with the indirect_return attribute if it is available.

This fixed:

    • Remove <chrono> dependency on _GLIBCXX_USE_C99_STDINT_TR1 · 8ba7f29e

turn allows most of <chrono> to be defined, which removes the dependency

    • [libgomp, nvptx] Add error with recompilation hint for launch failure · 88a4654d 
      Currently, when a kernel is lauched with too many workers, it results in a cuda
launch failure.  This is triggered f.i. for parallel-loop-1.c at -O0 on a Quadro
M1200.

This patch detects this situation, and errors out with a hint on how to fix it.

Build and reg-tested on x86_64 with nvptx accelerator.

    • combine: Another hard register problem (PR85805) · 328aa787 
      The current code in reg_nonzero_bits_for_combine allows using the
reg_stat info when last_set_mode is a different integer mode.  This is
completely wrong for non-pseudos.  For example, as in the PR, a value
in a DImode hard register is set by eight writes to its constituent
QImode parts.  The value written to the DImode is not the same as that
written to the lowest-numbered QImode!

    • [libgomp, openacc, testsuite] Fix async/wait logic in lib-13.f90 · b2eb1779 
      The purpose of the lib-13.f90 test-case is to test acc_wait_all_async.  The
test indeed calls acc_wait_all_async, but then subsequentlys calls
acc_wait_all, so the acc_wait_all_async functionality is not tested.
Furthermore, all acc_async_test calls are placed in a location where they are
not guaranteed to succeed, which explains why there's an xfail for the lower
optimization levels.

This patch fixes the problems by replacing acc_wait_all with an acc_wait on
the async id used for the acc_wait_all_async call, and moving the
acc_async_test calls to the correct locations.

Reg-tested on x86_64 with nvptx accelerator.
