[LLVMdev] [LLVMDev] Is there any way to eliminate zero-extension instruction?
Dear developers.
We try to make our own backend of llvm for our target machine.
Assume that we have the following code in our source code.
int i = ( a < b );
The code is translated into
r0 <- gt r1 r2
r3 <- and r0 0x1
We think that r3 is not necessary. Is there any way to eliminate it by just
modifying
our backend?
Thank you in advance.
