[LLVMdev] Value* to Instruction*/LoadInst* casting
Hello everyone,
Can you please tell me if it is possible in LLVM to cast a `Value*` to an
`Instruction*/LoadInst*` if for example `isa<LoadInst>(MyValue)` is true?
In my particular piece of code:
Value* V1 = icmpInstrArray[i]->getOperand(0);
Value* V2 = icmpInstrArray[i]->getOperand(1);
if (isa<LoadInst>(V1) || isa<LoadInst>(V2)){

6 separate instances of static getPointerOperand(). Time to consolidate?
LLVM friends,
I'm currently trying to make LoopVectorizationLegality class in Transform/Vectorize/LoopVectorize.cpp
more modular and eventually move it to Analysis directory tree. It uses several file scope helper functions
that do not really belong to LoopVectorize. Let me start from getPointerOperand(). Within LLVM, there are
five other similar functions defined.
I think it's time to

What LoopVectorize.cpp has are the following. Each function may have to have a separate consolidation discussion.
I'm bringing up getpointerOperand() since I actually found multiple instances defined/used.
DependenceAnalysis.cpp has isLoadOrStore(). LoopAccessAnalysis.cpp has getAddressSpaceOperand().
I'm sure there are others that might be worth discussing within this thread or a follow

[LLVMdev] global variable
Hi all,
I am newbie for llvm. I just create a global variable, there are some statements in my pass like:
LoadInst* int64_64 = new LoadInst(pthreadPID, "", false, OptAplusOne);
int64_64->setAlignment(8);
int64_64->dump();
LoadInst* int32_65 = new LoadInst(gvar_int32_myFlag, "", false, OptAplusOne);
int32_65->setAlignment(4);

[LLVMdev] Vector code
Hi Matthijs,
Yes, I've turned off the link-time optimizations (otherwise it just
propagates my constant vectors and immediate prints the result). :-)
Here's essentially what I try to generate:
void add(float z[4], float x[4], float y[4])
{
z[0] = x[0] + y[0];
z[1] = x[1] + y[1];
z[2] = x[2] + y[2];
z[3] = x[3] + y[3];
}
And here's part of the output from the online

How to get the destination in a LoadInst
Hi all,
I have %5 = load i32, i32* %3, align 4 LoadInst and I would like to get
reference to the destination ( in this case %5 ). How can I do that?
Thanks

[LLVMdev] Vector code
llvm does not automatically vectorize your scalar code (as least for
now). You have to write gcc generic vector code or use vector builtins.

[LLVMdev] How to Load a Value?
Hello,
I have a problem of generating a load instruction. The LLVM bytecode is:
------------------------
entry:
...
%2 = call i32 (...)* @atoi(i8*%1) nounwind
/*<- Insertpos*/
...
--
bb1:
..
%5 = icmp sgt i32 %2, %i.0

-----------------
Now I have
pb: pointer to the Value object of *%2* of bb1.
Here, I want to generate a load instruction and I did it as:

Extending StoreInst/LoadInst
Hi,
I am trying to figure out the best way to add some extra metadata to the store and load llvm-ir instructions:
The metadata content is a 'Value*' expression representing a side channel, containing dependency information that is used to help the Scoped Alias Analysis.
Optimizations that don't know about this side channel can safely drop it, where the only effect would be on the

How to get the destination in a LoadInst
Hi,
I would like to get the '5'. I would like to know where the loaded value is
stored. I don't know which method I should use of the LoadInst class.
Hope this clarifies

[LLVMdev] GetElementPtrInst question
Hi all,
How can I create an llvm::GetElementPtrInst in which the pointer and
the index are in registers previously loaded with llvm::LoadInst ? I
mean, the generated instruction will be like this:
%1 = getelementptr i8* %myreg1, i32 %myreg2
here, %myreg1 and %myreg2 are previously created by load instructions
(llvm::LoadInst).
Please, let me know if there is an example of something similar.

[LLVMdev] How to load a data from the address of unsiged long type
Now I have an address that present in a unsigned long address like the

But I do not know how to read the data from the above addr varaible. I
tried the following three kind of code:

[LLVMdev] getting object from BitCastInst?
My pass is looking at StoreInsts acting on global variable that happen
to be function pointers. From these StoreInsts I would like to get
useful information(the function used if a direct assignment, function
pointer used, etc) from the getValueOperand() method. Looking through
several examples I see that this can return several things like:
GlobalVariable, Function, LoadInst or BitCastInst

[LLVMdev] LoadInst result
Folks,
I have a LLVM instruction like the following
%0 = load i32** %pp, align 8
I have a LoadInst &inst handle to this instruction. In addition, i could access the pointer being loaded from using the inst.getPointerOperand...
However, is there a way to access the handle to the value being loaded? Essentially, i wanted to access the %0 in the statement listed.
The end goal is

[LLVMdev] LLVM: Very simple question
Hi, guys. I'm a newbie to LLVM and have a very simple question.
Which instructions should I use (in terms of IRBuilder calls) to allocate an
array of bytes in stack (alloca?), then to work with it (from a given
offset) as with integer (bitcast?). I mean something like that:
unsigned char var[8];
unsigned int offset = 3;
int val = *(int*)(&var+offset); /* read */
*(int*)(&var+offset)
