[LLVMdev] global variable uses
Hi,
I'm trying to change all uses of a global variable so they'll use a
different global variable.
For instance, I have:
@a = global [100 x [100 x i64]] zeroinitializer, align 16
@b = global [100 x [100 x i64]] zeroinitializer, align 16
And I want to change the use
%arrayidx = getelementptr inbounds [100 x [100 x i64]]* @a, i32 0, i64 %3
to
%arrayidx = getelementptr inbounds

[LLVMdev] About user of bitcast/GEP instruction
...it only erase lifetime instrinsics ?

// The only users of this bitcast/GEP instruction are lifetime
intrinsics.
// Follow the use/def chain to erase them now instead of leaving it

for (auto UUI = I->user_begin(), UUE = I->user_end(); UUI != UUE;) {
Instruction *Inst = cast<Instruction>(*UUI);
++UUI;
Inst->eraseFromParent();

Efficient way to identify an instruction
...en is a bit confusing, but this returns an iterator range you can iterate through to find instructions that depend on a given one.
Similarly, you have the function ‘uses()’ that can be used to traverse down the DAG when instructions are still on SSA form.
Look also at the related functions 'user_end()’, 'user_begin()’, 'use_end()' and 'use_begin()
I hope this helps.

[LLVMdev] About user of bitcast/GEP instruction
Hi,
In PromoteMemoryToRegister.cpp, it seems to rely on the fact that the only
users of bitcast/GEP instruction are lifetime intrinsics
(llvm.lifetime.start/end). I did some searching in llvm/test folder, it
seems to be true.
However, by reading LLVM IR manual, I don't see any restriction stated on
the possible user of bitcast/GEP instruction. So my question is who impose
the restriction ?

[LLVMdev] RFC: Missing canonicalization in LLVM
So this change did indeed have an effect! :)
I’m seeing regressions in a number of benchmarks mainly due to a host of extra bitcasts that get introduced. Here’s the problem I’m seeing in a nutshell:
1) There is a Phi with input type double
2) Polly demotes the phi into a load/store of type double
3) InstCombine canonicalizes the load/store to use i64 instead of double
4)

Efficient way to identify an instruction
Hi Tim,
as always thanks for your help. Unfortunately I made a mistake in my email
but apart from that I still have problems.
