This change seems to have broken one of our tests in emscripten. I reduced it to this:
#include <stdlib.h>
#include <assert.h>
int main() {
void * ptr = aligned_alloc(3, 64);
assert(ptr == NULL);
return 0;
}
$ clang -O2 -c test.c
clang: /usr/local/google/home/sbc/dev/wasm/llvm-project/llvm/include/llvm/Support/Alignment.h:138: llvm::MaybeAlign::MaybeAlign(uint64_t): Assertion `(Value == 0 || llvm::isPowerOf2_64(Value)) && "Alignment is neither 0 nor a power of 2"' failed.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace, preprocessed source, and associated run script.
