2020-06-22build: Use -include instead of conditional include.David Edelsohn2-6/+2
Automake and GNU Make both use the endif keyword, which conflicts and elicits an error for matching if/ifdef and endif.

2020-06-21aix: Add GCC64 configuration and FAT target libraries.David Edelsohn6-2/+66
This patch adds the ability to configure GCC on AIX to build as a 64 bit application and to build target libraries "FAT" libraries in both 32 bit and 64 bit mode. The patch adds makefile fragment hooks to target libraries that allows them to include target-specific rules. The target specific rules for AIX place both 32 bit and 64 bit objects and shared objects in archives at the top-level, not multilib subdirectories. The multilibs are built in subdirectories, but must be combined during the last parts of the target library build process. Because of the way that GCC bootstrap works, the libraries must be combined during the multiple stages of GCC bootstrap, not solely when installed in the final destination, so the libraries are correct at the end of each target library build stage, not solely an install recipe. gcc/ChangeLog 2020-06-21 David Edelsohn <dje.gcc@gmail.com> * config.gcc: Use t-aix64, biarch64 and default64 for cpu_is_64bit. * config/rs6000/aix72.h (ASM_SPEC): Remove aix64 option.

2020-02-12Use a non-empty test program to test ability to link.Sandra Loosemore2-2/+9
On bare-metal targets, I/O support is typically provided by a BSP and requires a linker script and/or hosting library to be specified on the linker command line. Linking an empty program with the default linker script may succeed, however, which confuses libstdc++ configuration when programs that probe for the presence of various I/O features fail with link errors. 2020-02-12 Sandra Loosemore <sandra@codesourcery.com> PR libstdc++/79193 PR libstdc++/88999 config/ * no-executables.m4: Use a non-empty program to test for linker support. libgcc/ * configure: Regenerated. libgfortran/ * configure: Regenerated. libiberty/ * configure: Regenerated. libitm/ * configure: Regenerated. libobjc/ * configure: Regenerated. libquadmath/ * configure: Regenerated. libssp/ * configure: Regenerated. libstdc++v-3/ * configure: Regenerated.
2020-01-24Add `--with-toolexeclibdir=' configuration optionMaciej W. Rozycki5-4/+49
Provide means, in the form of a `--with-toolexeclibdir=' configuration option, to override the default installation directory for target libraries, otherwise known as $toolexeclibdir. This is so that it is possible to get newly-built libraries, particularly the shared ones, installed in a common place, so that they can be readily used by the target system as their host libraries, possibly over NFS, without a need to manually copy them over from the currently hardcoded location they would otherwise be installed in.
