Hi, all I try to get the Instructions where one function use the global variable. for (llvm::Module::global_iterator gvar_iter = M.global_begin(); gvar_iter != M.global_end(); gvar_iter++) { llvm::GlobalVariable *gvar = &*gvar_iter; llvm::errs() << "const global var: " << gvar->getName() << "\n"; for (

Thanks for your help. Is there possible I can get the realily case value form the MI? For the case in https://bugs.llvm.org/show_bug.cgi?id=34902. as follows. ############################# * GCC v7.1 generated assembly ############################# ** Options: -Os -marm -march=armv7-a foo: @ args = 0, pretend = 0, frame = 0 @ frame_needed = 0, uses_anonymous_args = 0 sub

Hi, guys I am interesting about how to get the switch case value form the Machine Instruction. I know the switch will be converted to jump-table in the Machine Instruction. And in the phase CodeGen , the case-value of SwitchInst can get esasly. but it seems no case -value in Machine Instruction. The MI as follows: Frame Objects: fi#0: size=1, align=0, at location [SP] fi#1: size=4,

Some glitch in the emailer? I have received this message 3 times in a row!? I think that by the time it gets as far as MI-level there is no reversible method of determining the 'case' label at all. The reason I say this, is that I have often seen optimisations that coalesce groups of values into interesting logical tests and jump-tables are completely avoided. For example, a simple

Hi, First of all, please note: as of v3.1, C backend has been thrown away for being "buggy" and "unmaintained". Several months ago there was a similar question, and it was solved.

Hi all, How do I obtain the current active path of a function that's being called? That's to say, I have several source files and they all contain definition of function A. I would like to figure out which function A and from which file is the one that's being called and is currently active? Thanks a lot! [[alternative HTML version deleted]]

Dear all, I'm using the package adehabitat in R to import several .asc files (=matrix), and also create a kasc object (=dataframe) with all of them. The main idea is to use this kasc object to map the predicted values of climate-matching model for an overall area. However, I don't know how to proceed: Do I have to project the model (already stored in R) onto the kasc object directly, or

Hi, How can I obtain the upper bound of a pointer in the code? For example, I have a pointer Ptr which points to a block of memory that is allocated by malloc, say, Ptr = malloc(size); Then what should I do if I am going to get the upper bound of the memory block that is pointed to by Ptr in the runtime? Thanks, Ben -------------- next part -------------- An HTML attachment was scrubbed...

This is rather off-topic for LLVM, it's a C programming question and the C answer is: you can't. C doesn't expose any way to find the upper limit of 'Ptr' you just have to keep track of what size you used yourself.

I am having problems passing analysis results to transformation passes, so I reduced my testcase into the following bare bone: Pass1: simple FunctionPass, counting functions Pass2: transformation pass, for now, just trying to obtain a reference of Pass1 using AU.getAnalysis<Pass1>() inside its runOnFunction(). When I run it, I get the following runtime error: opt -load

You're right. The assembly code only has the body of main function and the external function declaration puts declare i32 @puts(i8*) It makes sense, I think, that my

Suppose, I have a Pass1 implemented as a subclass of Pass, with source code in the directory of llvm source base( transform/analyze ) I can run that pass through opt on the bytecode emitted by gcc frontend through opt tool. However, I want that Pass1 to be the part of the actual GCC compiler. I want to know how I can position Pass1 among other passes /optimizations/ code generations. e.g if
