...for many of us and users of LLVM is that an assert build isn’t ABI compatible with a release build. The CMake flags that controls this behavior is LLVM_ABI_BREAKING_CHECKS ( LLVM_ABI_BREAKING_CHECKS:STRING Used to decide if LLVM should be built with ABI breaking checks or not. Allowed values are WITH_ASSERTS (default), FORCE_ON and FORCE_OFF. WITH_ASSERTS turns on ABI breaking checks in an assertion enabled build. FORCE_ON (FORCE_OFF) turns them on (off) irrespective of whether normal (NDEBUG-based) assertions are enabled or not. A version of LLVM built with ABI breaking checks is not ABI compatible...

Or am I misunderstanding?

Looks like Mehdi reverted already.

I cannot reproduce this error, but this could be real. David, is this reproducible every time or is this flaky?

Everyone, The following patch to reverse iterate SmallPtrSet's has now been merged: https://reviews.llvm.org/D26718 This is how LLVM behavior will change due to this patch: - In LLVM builds with *assertions enabled*, SmallPtrSet's would always be reverse iterated by default. This default behavior can be overridden via the flag "-mllvm -reverse-iterate=<true/false>".

That seems to work (see below). $ cd

Everyone, There is non-determinism in LLVM codegen in the following scenarios: 1. Between back-to-back runs of the same LLVM toolchain 2. Between Release vs Release+Asserts toolchains 3. Between Linux vs Windows toolchains The main reasons for the non-determinism in codegen are: 1. Iteration of unordered containers (like SmallPtrSet, DenseMap, etc) where the iteration order is undefined 2.

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:
