Yes, that’s right. Some LLVM terminology though: The blocks you mention, are called the “exiting blocks” of the loop, and the blocks outside the loop (that are the targets of these exiting blocks) are called the exit blocks. getExitingBlocks in LoopInfoImpl.h is the code you’re interested in. By definition: one of the successor’s of the exiting block is an exit block, and it should have another

Hello, I have a question about exit blocks : is it true that every loop's exit block will contain only those comparisons that will lead to exit or to continue execution in loop? I have tried many examples , after optimizations it seems to be true, but does it have to be so? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, in https://reviews.llvm.org/D52143 there's some uncertainty if LLVM code prefers if (!Function()) // Call to function failed, deal with it or if (Function()) // Call to function failed, deal with it (Note that this is about functions returning bool, not int.) Folks on that review feel that returning true on success is probably what we want, but it's not documented

Trying to run a self host "ninja check-clang" with ASan enabled I hit a /lot/ of errors like this (strangely I hit none of these in check-llvm, only in check-clang): Any ideas? ==10525==ERROR: AddressSanitizer failed to deallocate 0x10800 (67584) bytes at address 0x631000014800 ==10525==AddressSanitizer CHECK failed:
