From: Tom Tromey Date: Thu, 19 Dec 2019 23:40:15 +0000 (-0700) Subject: Move many configure checks to common.m4 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=05ea2a051030a452bb1f4710dafeb1054cf38c17;p=binutils-gdb.git Move many configure checks to common.m4 This moves many needed configure checks from gdb and gdbserver into common.m4. This helps gdbsupport, nat, and target be self-contained. The result is a bit spaghetti-ish, because gdbsupport uses another m4 file from gdb/. The resulting code is somewhat non-obvious. However, these problems already exist, so it's not really that much worse than what is already done. gdb/ChangeLog 2020-01-14 Tom Tromey * configure: Rebuild. * configure.ac: Move many checks to ../gdbsupport/common.m4. gdb/gdbserver/ChangeLog 2020-01-14 Tom Tromey * configure: Rebuild. * configure.ac: Remove any checks that were added to common.m4. * acinclude.m4: Include lib-ld.m4, lib-prefix.m4, and lib-link.m4. gdbsupport/ChangeLog 2020-01-14 Tom Tromey * configure, Makefile.in, aclocal.m4, common.m4, config.in: Rebuild. * common.m4 (GDB_AC_COMMON): Move many checks from gdb/configure.ac. * acinclude.m4: Include bfd.m4, ptrace.m4.
