From 9467110bae19116ba041118b7d26d675e87506ce Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Tue, 5 Nov 2013 09:54:03 -0700 Subject: gdb configure updates Now that the configury needed for the "common" and "target" directories is in common.m4, some code in gdb's configure.ac is redundant. I ran this script after making an "ID" file using mkid: sed -n 's/^.*\(HAVE_[A-Z0-9_]*\).*$/\1/p' config.in | while read x; do echo ===== $x gid $x | egrep -v '^(testsuite|gnulib|common|target|gdbserver)/' done This finds all the spots using HAVE_ defines, and, more importantly, makes it clear which defines aren't used in the main parts of gdb. From this I came up with this patch to remove all the unused bits. There are a few that are subtly used -- for example the configure script sometimes checks internal configure cache variables, meaning some checks cannot be removed. 2013-11-08 Tom Tromey * configure, config.in: Rebuild. * configure.ac: Remove unused configury. --- gdb/configure | 206 +++------------------------------------------------------- 1 file changed, 8 insertions(+), 198 deletions(-) (limited to 'gdb/configure') diff --git a/gdb/configure b/gdb/configure index 8844c900314..1728d091a1d 100755 --- a/gdb/configure +++ b/gdb/configure @@ -8914,15 +8914,15 @@ $as_echo "#define STDC_HEADERS 1" >>confdefs.h fi # elf_hp.h is for HP/UX 64-bit shared library support. -for ac_header in nlist.h machine/reg.h poll.h sys/poll.h sys/socket.h proc_service.h \ - thread_db.h signal.h stddef.h \ - stdlib.h string.h memory.h strings.h sys/fault.h \ +for ac_header in nlist.h machine/reg.h poll.h sys/poll.h proc_service.h \ + thread_db.h stddef.h \ + stdlib.h sys/fault.h \ sys/file.h sys/filio.h sys/ioctl.h sys/param.h \ sys/resource.h sys/procfs.h sys/ptrace.h ptrace.h \ sys/reg.h sys/debugreg.h sys/select.h sys/syscall.h \ - sys/types.h sys/wait.h wait.h termios.h termio.h \ - sgtty.h unistd.h elf_hp.h locale.h \ - dlfcn.h sys/un.h linux/perf_event.h + termios.h termio.h \ + sgtty.h unistd.h elf_hp.h \ + dlfcn.h do : as_ac_Header=`$as_echo "ac_cv_header_$ac_header" | $as_tr_sh` ac_fn_c_check_header_mongrel "$LINENO" "$ac_header" "$as_ac_Header" "$ac_includes_default" @@ -9045,36 +9045,6 @@ fi cat >>confdefs.h <<_ACEOF #define HAVE_DECL_REALLOC $ac_have_decl _ACEOF -ac_fn_c_check_decl "$LINENO" "strerror" "ac_cv_have_decl_strerror" "$ac_includes_default" -if test "x$ac_cv_have_decl_strerror" = x""yes; then : - ac_have_decl=1 -else - ac_have_decl=0 -fi - -cat >>confdefs.h <<_ACEOF -#define HAVE_DECL_STRERROR $ac_have_decl -_ACEOF -ac_fn_c_check_decl "$LINENO" "strstr" "ac_cv_have_decl_strstr" "$ac_includes_default" -if test "x$ac_cv_have_decl_strstr" = x""yes; then : - ac_have_decl=1 -else - ac_have_decl=0 -fi - -cat >>confdefs.h <<_ACEOF -#define HAVE_DECL_STRSTR $ac_have_decl -_ACEOF -ac_fn_c_check_decl "$LINENO" "getopt" "ac_cv_have_decl_getopt" "$ac_includes_default" -if test "x$ac_cv_have_decl_getopt" = x""yes; then : - ac_have_decl=1 -else - ac_have_decl=0 -fi - -cat >>confdefs.h <<_ACEOF -#define HAVE_DECL_GETOPT $ac_have_decl -_ACEOF ac_fn_c_check_decl "$LINENO" "snprintf" "ac_cv_have_decl_snprintf" "$ac_includes_default" if test "x$ac_cv_have_decl_snprintf" = x""yes; then : ac_have_decl=1 @@ -9084,16 +9054,6 @@ fi cat >>confdefs.h <<_ACEOF #define HAVE_DECL_SNPRINTF $ac_have_decl -_ACEOF -ac_fn_c_check_decl "$LINENO" "vsnprintf" "ac_cv_have_decl_vsnprintf" "$ac_includes_default" -if test "x$ac_cv_have_decl_vsnprintf" = x""yes; then : - ac_have_decl=1 -else - ac_have_decl=0 -fi - -cat >>confdefs.h <<_ACEOF -#define HAVE_DECL_VSNPRINTF $ac_have_decl _ACEOF @@ -10159,10 +10119,10 @@ fi for ac_func in canonicalize_file_name realpath getrusage getuid getgid \ pipe poll pread pread64 pwrite readlink resize_term \ sbrk setpgid setpgrp setsid \ - sigaction sigprocmask sigsetmask socketpair syscall \ + sigaction sigprocmask sigsetmask socketpair \ ttrace wborder wresize setlocale iconvlist libiconvlist btowc \ setrlimit getrlimit posix_madvise waitpid lstat \ - fdwalk pipe2 ptrace64 + ptrace64 do : as_ac_var=`$as_echo "ac_cv_func_$ac_func" | $as_tr_sh` ac_fn_c_check_func "$LINENO" "$ac_func" "$as_ac_var" @@ -11396,80 +11356,6 @@ $as_echo "#define _KMEMUSER 1" >>confdefs.h fi if test "$ac_cv_header_sys_procfs_h" = yes; then - { $as_echo "$as_me:${as_lineno-$LINENO}: checking for pstatus_t in sys/procfs.h" >&5 -$as_echo_n "checking for pstatus_t in sys/procfs.h...
