[LLVMdev] Help with Instruction Expansion on Mips
why do you want to "ban" certain instructions?
is this for some architectural variant?
the compiler is trying to match patterns from the target independent
part of the code generator.
if you remove instructions, the compiler in many cases will no longer be
able to match certain patterns
and you will get thos "can not select" messages.

[LLVMdev] Help with Instruction Expansion on Mips
Hi everyone,
I am a newbie to LLVM. I am trying to ban some of instructions in Mips
Instruction, for example, lh, lhu, sh, and etc.
I have tried to directly comment lh, lhu, and sh to make llvm not to choose
these instruction when compiling, however, it usually cause a 'can not
select ...' error when using 'short' data type in source code.
Then I tried to expand these instructions
