[LLVMdev] How do I find all memory allocations in an llvm ir code file?
I tried to compile this snippet of C++ code:
void FuncTest() {
int* a = new int;
int* b = new int[2];
}
using:
clang test.cpp -S -emit-llvm -o - > test.llvm
and obtained this:
define void @_Z8FuncTestv() {
entry:
%a = alloca i32*, align 4
%b = alloca i32*, align 4
%call = call noalias i8* @_Znwj(i32 4)
%0 = bitcast i8* %call to i32*
store i32* %0, i32** %a, align 4
%call1 = call noalias i8* @_Znaj(i32 8)
%1 = bitcast i8* %call1 to i32*
store i32* %1, i32** %b, align 4
ret void
}...
