From cbd51548dc1869fde58b621ea3c2fc9386947ea9 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Mon, 29 Aug 2011 19:52:13 -0400 Subject: [PATCH] Replace obsolete AC_LANG_FUNC_LINK_TRY autoconf macro. The version of this macro used in autoconf 2.59 is capable of incorrectly succeeding (ie, reporting that a library function is available when it isn't), if the compiler performs link-time optimization and decides that it can optimize the function reference away entirely. Replace it with the coding used in autoconf 2.61 and later, which forces the program result to depend on the function's result so that it cannot be optimized away. This should fix build failures currently being seen on buildfarm member anchovy. This patch affects the 8.2 and 8.3 branches only, since later branches are using autoconf versions that don't have this problem. --- config/c-library.m4 | 69 ++++++ configure | 554 ++++++++++++++++++-------------------------- 2 files changed, 298 insertions(+), 325 deletions(-) diff --git a/config/c-library.m4 b/config/c-library.m4 index 31dba1cbfd..d8d5dcd5b6 100644 --- a/config/c-library.m4 +++ b/config/c-library.m4 @@ -297,3 +297,72 @@ int main() ])dnl AC_CACHE_VAL AC_MSG_RESULT([$pgac_cv_printf_arg_control]) ])# PGAC_FUNC_PRINTF_ARG_CONTROL + + +# backport improved FUNC_LINK_TRY test from Autoconf 2.61, cf +# http://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=commitdiff;h=f50d0bd4c7d92fbabcd9169920a23889524790e7 +# This is needed to avoid incorrect results when compiler does link-time +# optimization. + +# AC_LANG_CALL(C)(PROLOGUE, FUNCTION) +# ----------------------------------- +# Avoid conflicting decl of main. +m4_define([AC_LANG_CALL(C)], +[AC_LANG_PROGRAM([$1 +m4_if([$2], [main], , +[/* Override any GCC internal prototype to avoid an error. + Use char because int might match the return type of a GCC + builtin and then its argument prototype would still apply. */ +#ifdef __cplusplus +extern "C" +#endif +char $2 ();])], [return $2 ();])]) + + +# AC_LANG_FUNC_LINK_TRY(C)(FUNCTION) +# ---------------------------------- +# Don't include because on OSF/1 3.0 it includes +# which includes which contains a +# prototype for select.
