@GermanAizek @BenBE I know this one is merged, but I have a question: How can TCC optimize out the If there's no prototype for In other words, the AC_LINK_IFELSE(
[AC_LANG_PROGRAM(
[],
[[return __builtin_ctz(1U); /* Supported in GCC 3.4 or later */]]
)],
AC_DEFINE([HAVE_BUILTIN_CTZ], 1, [Define to 1 if the compiler supports '__builtin_ctz' function.])
AC_MSG_RESULT(yes),
AC_MSG_RESULT(no)
)Yeah, a Would @GermanAizek like to help test out if this change work on checking TCC? (I can file a separate PR for this change.) |

Wow! I am surprised by the compilation speed on TCC, as well as the resource consumption on monitoring
Building with -DNDEBUG macro by default.
I think Gentoo users will idolize Fabrice Bellard.
