[llvm-branch-commits] [llvm] [Sparc] limit MaxAtomicSizeInBitsSupported to 32 for 32-bit Sparc. (#81655) (PR #81713)
https://github.com/brad0 created https://github.com/llvm/llvm-project/pull/81713
When in 32-bit mode, the backend doesn't currently implement 64-bit atomics,
even though the hardware is capable if you have specified a V9 CPU. Thus, limit
the width to 32-bit, for now, leaving behind a TODO.
This fixes a regression triggered by PR #73176.

Looking at the PR I am not sure that was clear and @yingopq might have
interpreted your comment as to remove all together.

[llvm-branch-commits] [clang] 018984a - [PowerPC] Fix va_arg in C++, Objective-C on 32-bit ELF targets

LOG: [PowerPC] Fix va_arg in C++, Objective-C on 32-bit ELF targets
In the PPC32 SVR4 ABI, a va_list has copies of registers from the function call.
va_arg looked in the wrong registers for (the pointer representation of) an
object in Objective-C, and for some types in C++. Fix va_arg to look in the
general-purpose registers, not the floating-point registers. Also fix va_arg
for some C++ types, like a member function pointer, that are aggregates for
the ABI.
Anthony Richardby found the problem in Objective-C. Eli Friedman suggested
part of this fix.
