[LLVMdev] Lowering intrinsics / type promotion
...intrinsic functions that have non-i32 operands. The target only supports 32-bit registers natively but for some operations, only the lower 16 bits are significant.
For example, the SMULS instruction does a 16 x 16 fractional multiply with saturation. I've defined an intrinsic function:
int __builtin_opus_smuls(short a, short b);
def int_opus_smuls : GCCBuiltin<"__builtin_opus_smuls">,
Intrinsic<[llvm_i32_ty], [llvm_i16_ty, llvm_i16_ty],
[IntrNoMem]>;
; ModuleID = 'test.c'
