Since updating to LLVM 3.3, the system is generating attributes such as: attributes #0 = { nounwind "less-precise-fpmad"="false" "no-frame-pointer-elim"="true" "no-frame-pointer-elim-non-leaf"="true" "no-infs-fp-math"="false" "no-nans-fp-math"="false" "unsafe-fp-math"="false" "use-soft-float"=...

Hi, everyone. I am new to llvm and I want to use C function “malloc" and “free" to do heap allocation, but It seems it is not a built-in function like ‘’printf” so I got an error “Unknown extern function”. I use ExecutionEngineer to run my main function and how should I do to make EE link the C library I want. Thanks.

Hello! clang defines some AttributeSet, for example: attributes #0 = { nounwind uwtable "less-precise-fpmad"="false" "no-frame-pointer-elim"="true" "no-frame-pointer-elim-non-leaf"="true" "no-infs-fp-math"="false" "no-nans-fp-math"="false" "unsafe-fp-math"="false" "use-soft-float"=...

Hi Jin, It's difficult to say just from looking at a pass, but one thing looked odd: > CallInst *call_print = CallInst::Create(call_print,paramArrayRef,"",ins_temp); This looks very dodgy. The "call_print" being used as an argument is the (uninitialised) one that's just been declared. This could be the source of the assertion failure (though a segfault is just as

Hi, I wanted to know if it was possible to force ARM backend to compile a function in ARM while the rest is in Thumb mode. I tried the attributes which is used in GCC but it doesn't work.

Hello, everyone! I want to write a pass which can insert a call "printf" instructions before every instruction in the LLVM IR. here is what I wrote: namespace { class call_print : public FunctionPass{ private: DenseMap<const Value*, int> inst_map; public: static char ID; call_print() : FunctionPass(ID){} //define a extern function "printf" static llvm::Function*
