[LLVMdev] Pinning registers in LLVM
...lower the above code to
something like this pseudo code:
{i32,i32} @main(i32 %in_esi) {
%esi = alloca i32
store in_esi -> esi
store 3 -> esi
esi1 = load esi
{esi2, dead} = call @printf(esi1, "register: %d\n", esi1);
store esi2 -> esi
esi3 = load esi
esi4 = esi3*2
store esi4 -> esi
esi5 = load esi
{esi6, dead} = call @printf(esi5, "register: %d\n", esi5);
store esi6 -> esi
esi7 = load esi
ret {esi7, 0}
}
Each of printf and main would be marked with the custom CC. After
running mem2reg on this, you'd get:...

[LLVMdev] Pinning registers in LLVM
Hi all,
I'm working on using LLVM as a back-end for an existing compiler (GHC
Haskell compiler) and one of the problems I'm having is pinning a
global variable to a actual machine register. I've seen mixed
terminology for this feature/idea, so what I mean by this is that I
want to be able to put a global variable into a specified hardware
register. This declaration should
