...nks for the suggestion i was trying to use the patch https://reviews.llvm.org/D30691 and ASTimporter concept for cross file analysis. Can u explain in details the approach u suggested ? What is `nm` on the object files ? Can u suggest some approach to start on this cross file analysis tool.

I see. Is there a pre-existing way to do this in LLVM? Cheers, ~Siddharth.

...the built Clang can compile C++ code with or without exceptions (using the -fno-exceptions). flag. Said another way Clang's implementation doesn't use exceptions but Clang itself can compile C++ code with or without exception support. Can anyone clarify on this comment ?

...nd gcc O0/O1/O2 give the same expected result. For Clang, O1 onwards results are wrong! This is because the load and store get hoisted and sinked in the loop in foo, respectively. That happens even though load(p1->f2) and store(p2->f1) are same address, but LLVM doesn’t find it.

...exceptions enabled, it just means we don't use them. Clang is a full C++ compiler. Even though LLVM & Clang do not use exceptions in their implementation, Clang does support compiling C++ code that uses exceptions.

Hi all, Can anyone explain why exceptions are disabled in LLVM, even if some C++ coding standard tells to use exceptions ?

yeah so when LTO runs, in the linker, it uses the target to produce object code. In the sense of code generation for target arch.

...d we want to analyze their ASTs to find out any dependency between them ( like a function defined in one c file is used in other, any external variable etc ). How can we do it at the AST level? I mean is there any automated tool or flag for it in LLVM. If anyone has any idea please tell. sincerely, Siddharth -------------- next part -------------- An HTML attachment was scrubbed...
