[PATCH] D57450: [RISCV] Set MaxAtomicInlineWidth and MaxAtomicPromoteWidth for RV32/RV64 targets with atomics

[James Y Knight via Phabricator via cfe-commits]

jyknight added a comment.

That GCC and Clang differ in handling of Atomics is a really unfortunate, longstanding issue.

See https://bugs.llvm.org/show_bug.cgi?id=26462

For RISCV, perhaps it's not yet too late to have the RISCV psABI actually specify a single ABI for C11 _Atomic which all compilers can implement, rather than having compilers do whatever they want to, separately...
