I can confirm that the issue has been caused by NDEBUG flag.

Hi all, An issue that come up from time to time and has cost hours for debug 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),

Hi, I have problem with IRBuilderBase::InsertPointGuard class that simply does not work in the release build of my project. The class does not restore the IRBuilder's insert point correctly when NDEBUG macro is set. It happens on OSX system only, trunk version of the LLVM built with brew. I suspect it is the ABI problem. InsertPointGuard uses AssertingVT for debug builds. LLDB gets confused

I'm pretty confident that there will be no problems - in practice

There are headers that conditionalize on NDEBUG, which could lead to ABI

Hi Mr/Mz, I have built and installed llvm-2.8 in debug mode using: >SRC_DIR/configure --prefix=INS_DIR --enable-debug-runtime --disable-optimized --enable-debug-symbols >make install It seems the NDEBUG controls a lot of print-out of debug information, by using DEBUG() or dbgs(). And it is said that NDEBUG is in enabled in debug mode, but I find it does not work and the -debug option

Hi, While audit our code, we found out a strange pattern in one of the LLVM headers and we were wondering if that was expected or if it should be fixed. Namely the problem looks like this: #ifndef NDEBUG // Define some variable. #endif assert(/*use this variable, i.e., outside of the ifndef NDEBUG scope*/); This happens in include/llvm/IR/ValueHandle.h for the variable Poisoned line 494

Good point, I forgot to check the standard. Given the clang was failing I assumed the code was wrong x). I am guessing there is something weird with the project, because indeed, paragraph 7.2 of the standard says: The assert macro is redefined according to the current state of NDEBUG each time that <assert.h> is included. > On Oct 4, 2017, at 2:53 PM, Craig Topper <craig.topper at

While we support compilation with CFLAGS=-DNDEBUG for the brave user desiring to avoid assertion overhead, this causes the tests to be less powerful. Fortunately, a quick test of './configure CFLAGS=-DNDEBUG' didn't hit any test failures, but it seems better to just ensure that assertions always work in our tests, even if they are turned off for the main binary.
