GCC's config/ChangeLog since the last time this merge was done (in the binutils-gdb commit0b4d000cc4) is included at the end of this commit message. It is worth noting that the binutils-gdb commit301a9420d9added the file config/debuginfod.m4 which is not present in GCC's config/ directory. This file is preserved, unmodified, after this commit. In order to regenerate all of the configure files, I configured with --enable-maintainer-mode, and built the 'all' target. I then did the same thing on a source tree without this patch, and only committed those files that changed when this patch was added.

# GCC_NO_EXECUTABLES
|
|
# -----------------
|
|
# FIXME: The GCC team has specific needs which the current Autoconf
|
|
# framework cannot solve elegantly. This macro implements a dirty
|
|
# hack until Autoconf is able to provide the services its users
|
|
# need.
|
|
#
|
|
# Several of the support libraries that are often built with GCC can't
|
|
# assume the tool-chain is already capable of linking a program: the
|
|
# compiler often expects to be able to link with some of such
|
|
# libraries.
|
|
#
|
|
# In several of these libraries, workarounds have been introduced to
|
|
# avoid the AC_PROG_CC_WORKS test, that would just abort their
|
|
# configuration. The introduction of AC_EXEEXT, enabled either by
|
|
# libtool or by CVS autoconf, have just made matters worse.
|
|
#
|
|
# Unlike the previous AC_NO_EXECUTABLES, this test does not
|
|
# disable link tests at autoconf time, but at configure time.
|
|
# This allows AC_NO_EXECUTABLES to be invoked conditionally.
