Here http://llvm.org/docs/ExceptionHandling.html#llvm_eh_selector llvm.eh.selector is declared like this: i32 %llvm.eh.selector <http://llvm.org/docs/ExceptionHandling.html#llvm_eh_selector>(i8*, i8*, i8*, ...)

...maintainers, please write something about your target. - Eric: should the new C API Changes part of the developer policy be pointed out? Maybe in relation to where we mention changes to the C API? - David: can you write something about the new IR for exception handling? Maybe just point into the ExceptionHandling doc? - Alex L: I've seen a lot of MIR patches but don't know the status. Anything to mention in the release notes? - Dylan: should we mention the new AVR target, or is it too early? - Richard: anything on the C++ front? What's the status on coroutines? - Jonathan and other OpenMP...

The first time you said “setjmp/longjmp intrinsics” I thought it was a typo, and that you were talking about the C standard library functions. If you’re actually talking about LLVM intrinsics, are they documented? I don’t see any intrinsics with those names in the language reference (https://llvm.org/docs/LangRef.html <https://llvm.org/docs/LangRef.html>). > On Mar 27, 2020, at 3:30 PM,

...es things greatly. As a toy project, I'm attempting to catch an exception that's thrown in a Windows x64 C++ library call from within an LLVM x64 MCJIT instance. The version I'm working with is LLVM 3.8.1, and the code I've created is based on the documentation http://llvm.org/docs/ExceptionHandling.html . I've also been reading up on the Exception toy/example code that's shipped with LLVM, as well as several mail discussions, the CGException class from clang and of course the ever useful 'clang --emit-llvm'. My aim here is to create a minimum working test case. My first at...

...ugh this option doesn't seem to have a switch from code, only from the llc command line. Unless I'm missing something obvious, this will always screw up debug info on Windows 32bits. The check in code to enable this calls: bool usesWindowsCFI() const { return ExceptionsType == ExceptionHandling::WinEH && (WinEHEncodingType != WinEH::EncodingType::Invalid && WinEHEncodingType != WinEH::EncodingType::X86); } Where EncodingType::X86: //Windows x86, uses no CFI, just EH tables The comment seems to imply there are EH tables for i386 Windows, how...

I don't think this is quite true. though it might be a useful simplification. Obviously it is true for volatile registers, but I believe the funclet receives a CONTEXT with the nonvolatiles restor...

...tions I would like to abort the script, by throwing an exception back to the code that called the ExecutionEngine::runFunction. Initially I had problems throwing exceptions from functions called from the JIT code, where the JIT code would handle the exceptions, but this was solved by setting llvm::ExceptionHandling to true. However, now I'm trying to abort the script all together, by throwing an (by the script) unhandled exception. As a proof-of-concept I used the online demo generator to generate C++ code for the following script; void test(void) { throw -1; } I added llvm::ExceptionHandling = tr...

Dear LLVM people, I have started playing with LLVM a little bit and I am thinking of using it to write some linear algebra software for my class. First, an off-topic "bug report" (?), I tried using llvm under cygwin with Vista 64 bits, and it hangs during the build process. It works fine under Vista 32 bits, with cygwin. I was reading the documentation and I am very excited by the

...g using llvm-g++ -S -emit-llvm and see how it does it. In short: throwing an exception is done by a library call which takes an exception object. Catching is done using the LLVM invoke instruction. The exception object is retrieved by an llvm.eh.exception intrinsic call. See http://llvm.org/docs/ExceptionHandling.html Ciao, Duncan.

...Clang work. For 32-bit SEH, there are prologue/epilogue instruction sequence to emit, setting try-level ([ebp-4]), recovering EBP ([ebp-18h]), and all these can only happen in LLVM, not Clang. In my opinion, we should implement these as LLVM intrinsics, like the gcc ones: see http://llvm.org/docs/ExceptionHandling.html#exception-handling-intrinsics. Also, we should emit the tables for each function, which is not a simple task either. For 64-bit SEH, things are simpler. There are no more instructions to emit than no-SEH code. We have only two tasks: emit the table for each function, and place some code ri...
