From: Glenn Morris Date: Tue, 4 May 2010 02:56:19 +0000 (-0700) Subject: Move C_SWITCH_MACHINE, C_SWITCH_SYSTEM from cpp to autoconf. X-Git-Tag: emacs-pretest-24.0.90~104^2~275^2~438^2~293 X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=496287859b525d24bf38ef19a38ea2fd7d309bd1;p=emacs.git Move C_SWITCH_MACHINE, C_SWITCH_SYSTEM from cpp to autoconf. * configure.in (C_SWITCH_MACHINE, C_SWITCH_SYSTEM): New output variables, replacing c_switch_machine, c_switch_system. * src/s/aix4-2.h (C_SWITCH_SYSTEM): * src/m/alpha.h (C_SWITCH_MACHINE): Move to configure.in. * src/Makefile.in (C_SWITCH_MACHINE, C_SWITCH_SYSTEM): New variables, set by configure. (ALL_CFLAGS): Use $C_SWITCH_MACHINE and $C_SWITCH_SYSTEM in place of $c_switch_machine and $c_switch_system. * lib-src/Makefile.in: Use @C_SWITCH_SYSTEM@, @C_SWITCH_MACHINE@ rather than @c_switch_system@, @c_switch_machine@. --- diff --git a/ChangeLog b/ChangeLog index 3e26dc47626..efcc5991fb7 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,8 @@ +2010-05-04 Glenn Morris + + * configure.in (C_SWITCH_MACHINE, C_SWITCH_SYSTEM): New output + variables, replacing c_switch_machine, c_switch_system. + 2010-05-03 Glenn Morris * configure.in (LIBXT_OTHER, LIBX_OTHER): New output variables. diff --git a/configure.in b/configure.in index 34358a2cea1..184dbef6ff1 100644 --- a/configure.in +++ b/configure.in @@ -883,15 +883,7 @@ echo ' #ifndef LIBS_SYSTEM #define LIBS_SYSTEM #endif -#ifndef C_SWITCH_SYSTEM -#define C_SWITCH_SYSTEM -#endif -#ifndef C_SWITCH_MACHINE -#define C_SWITCH_MACHINE -#endif configure___ libsrc_libs=LIBS_SYSTEM -configure___ c_switch_system=C_SWITCH_SYSTEM -configure___ c_switch_machine=C_SWITCH_MACHINE configure___ LIBX=-lX11 @@ -969,12 +961,43 @@ rm ${tempcname} ac_link="$ac_link $ld_switch_system" + +C_SWITCH_MACHINE= +if test "$machine" = "alpha"; then + AC_CHECK_DECL([__ELF__]) + if test "$ac_cv_have_decl___ELF__" = "yes"; then + ## With ELF, make sure that all common symbols get allocated to in the + ## data section.
