[LLVMdev] code generation removes duplicated instructions
...el %bb8
The following is the arm code generated for the above block (llc with -O0):
.LBB0_26: @ %bb7
@ in Loop: Header=BB0_28 Depth=2
ldr r0, [sp, #440]
add r0, r0, #1
cmp r0, r0
str r0, [sp, #288]
bne .LBB0_88
b .LBB0_27
.LBB0_27: @ %bb7.split
@ in Loop: Header=BB0_28 Depth=2
ldr r0, [sp, #288]
str r0, [sp, #440]
The code generated for x86 for the same two blocks looks like as follows
(again llc with -O0):
.LBB0_26:...

If the two instructions are only similar in your real example, than
you need to make them similar in your test, not identical. Different
offsets, different array...

[LLVMdev] code generation removes duplicated instructions
Hi Renato,
I am trying to add a intrinsic call between the similar two instructions
which either I'll remove or convert to nop in codegen.
Does that kind of seem appropriate for the purpose here?
Thanks
Daya
