.... > How are you dealing with the fact that code gets relocated during loading? You talk about the loading phase during the link? If yes, this is why a do the post-processing after the link. If you talk about something like the -fpie parameter, I used a small trick. The function who will call isModified will calculate the offset dynamically. To do this, you get the address in IR (in C++ this is like (uint64_t)std::addressof(main);) and I remove a constant value. During the post-processing (again) I will update this constant value with the address into the binary. This will give you an offset...

...I create in IR a function who take 2 parameters, a begin and an end value. This function perform an hash over the code area (from begin to end) and return it. At first, I don’t know the addresses and the hash value so I put random value (it is an integer 64 bits). The function look like uint32_t isModified(uint64_t* begin, uint64_t* end). Once the compilation is over, I need to update the begin address, end address and the hash value. When I say the compilation is over, I mean the clang driver has finished all of his action (compiling, linking, etc.). Greetings, Johan > On 22 Feb 2016, at...

Hi, I want to know if it is possible to pass information from IR to the final binary (like a constant value)? I have a module pass in IR who make some transformation and, once the compilation is finished, I need to apply a post-processing. The post-processing need information from the IR part.

Hi Chris, I took a haste look at the "Points-to Analysis in Almost Linear Time" by Steens , your PHD thesis and SteensGaard.cpp in LLVM this afternoon. So I think: 1. Actually the basic algorithm described originally by SteensGaard does not provide MOD/REF information for functions. 2. The context insensitive part of Data Structure Analysis (LocalAnalysis) can be deemed as an
