Calling AC_CHECK_DECLS before we've finished setting up the compiler's CFLAGS seems like a pretty risky proposition, especially now that the first use of that macro will result in a test to see whether the compiler gives warning or error for undeclared built-in functions. That answer could very easily get changed later than where PGAC_LLVM_SUPPORT is called; furthermore, it's hardly unlikely that flags such as -D_GNU_SOURCE could change visibility of declarations. Hence, be a little less cavalier about where to do LLVM-related tests. This results in v11 and HEAD doing the warning-or-error check at the same place in the script as older branches are doing it, which seems like a good thing. Per further thought about commits |
