NVVM IR specification defines them with i32 return type:
declare i32 @llvm.nvvm.match.any.sync.i64(i32 %membermask, i64 %value)
declare {i32, i1} @llvm.nvvm.match.all.sync.i64(i32 %membermask, i64 %value)
...
The i32 return value is a 32-bit mask where bit position in mask corresponds
to thread’s laneid.
as well as PTX ISA:
9.7.12.8. Parallel Synchronization and Communication Instructions: match.sync
match.any.sync.type d, a, membermask;
match.all.sync.type d[|p], a, membermask;
...
Destination d is a 32-bit mask where bit position in mask corresponds
to thread’s laneid.
Additionally, ptxas doesn't accept intructions, produced by NVPTX backend.
After this patch, it compiles with no issues.
