[Dávid Bolvanský via Phabricator via llvm-commits]

xbolva00 added a comment.

Oh, this is funny (or nasty) bug

a.c
int foo(void) __attribute__((const));

int main(void) {

  __builtin_assume(foo() == 1);

}

b.c
#include <stdio.h>

int foo(void) {

  puts("BUM");
  return 0;

}

clang -O3 a.c b.c -o bum

./bum
BUM
