Add a custom intrinsic to the ARM backend
Hi,
I'm trying to add a new intrinsic to the ARM backend. The intrinsic should
a custom comparison.
To do so, I started with first defining the intrinsic in
llvm/include/llvm/IR/intrinsicsARM.td:
def int_foo_cmp : Intrinsic<[llvm_i32_ty], [llvm_i32_ty, llvm_i32_ty], []>;
The second step I did is adding a new pseudo instruction matching that
intrinsic in lib/Target/ARM/ARMInstInfo.td:
