Emit error for use of 128-bit integer inside device code had been
already implemented in https://reviews.llvm.org/D74387. However,
the error is not emitted for SPIR64, due for SPIR64 hasInt128Type
hasInt128Type: is also used to control generation of certain 128-bit
predefined macros, initializer predefined 128-bit integer types and
build 128-bit ArithmeticTypes. Except predefined macros, only the
device target is considered, since error only emit when 128-bit
integer is used inside device code, the host target (auxtarget) also
needs to be considered.
The change address:
- (SPIR.h) Correct hasInt128Type() for SPIR targets.
- Sema.cpp and SemaOverload.cpp: Add additional check to consider host target(auxtarget) when call to hasInt128Type. So that int128_t and int128() are allowed to avoid error when they used outside device code.
- SemaType.cpp: add check for SYCLIsDevice to delay the error message. The error will be emitted if the use of 128-bit integer in the device code.
