[LLVMdev] Avoiding Constant Folding
Hi All,
My codegen is trying to generate some thing like this:
entry:
....
%34 = icmp ne i32 %33, 15
br i1 %34, label %then, label %else
then: ; preds = %entry
%returnValue = or i1 true, false
....
br label %ifmerge
else: ; preds = %entry
br label %ifmerge
ifmerge:

[LLVMdev] How to make X86FastISel generate code for some intrinsic functions
Hi All,
I want to use Fast Instruction Selection for my X86 back-end. However, my
code often uses these two intrinsic functions: x86_sse_movmsk_ps and
x86_sse2_pcmpeq_d, which are not supported yet by X86FastISel.
Could you guys please show me how to add support for this two Intrinsics?
Pointing out one example would be great, I can follow to implement others.
I just know that I need to modify

[LLVMdev] Avoiding Constant Folding
Thank you guys, now I understand the problem.
I am trying to avoid using stack memory (or mutable variable is the term
used in the tutorial). I am also trying to optimize the code as much as I
can before using optimizer passes such as mem2reg (to reduce the compile
time as well).
With regards,
