commit r12-7583-g248bbcb2c3212bcb9f2a485b591dd37371133402

[nvptx] Use atom.and.b64 instead of atom.b64.and
The ptx manual prescribes the instruction format atom{.space}.op.type but the
compiler currently emits:
...
atom.b64.and %r31, [%r30], %r32;
...
which uses the instruction format atom{.space}.type.op.
Fix this by emitting instead:
...
atom.and.b64 %r31, [%r30], %r32;
...
Tested on nvptx.
gcc/ChangeLog:
2022-03-07 Tom de Vries <tdevries@suse.de>
* config/nvptx/nvptx.md (define_insn "atomic_fetch_<logic><mode>"):
Emit atom.and.b64 instead of atom.b64.and.
gcc/testsuite/ChangeLog:
2022-03-07 Tom de Vries <tdevries@suse.de>
* gcc.target/nvptx/atomic_fetch-1.c: Update.
* gcc.target/nvptx/atomic_fetch-2.c: Update.
