We currently have two ways to distinguish GNU and non-GNU assemblers and linkers: * USE_GAS and USE_GLD, defined via gcc/config/usegas.h and usegld.h which are included via config.gcc * HAVE_GNU_AS and HAVE_GNU_LD, determined from gcc/configure.ac This is confusing and leads to weird mistakes like combining both into an undefined USE_GNU_LD. Since both are based on the same info ($gas resp. $gnu_ld in gcc/configure.ac), it seems best to standardise on one of them. Since the USE_* form is almost exclusively used in Solaris-specific contexts, it's clearer to use the HAVE_GNU_* forms instead. This is what this patch does. Most of the changes are either Solaris-specific or border on obvious. Outside of Solaris code, there are only two cases: * gcc/config/ia64/hpux.h has one macro guarded by !USE_GAS. This wasn't defined before since the configuration for this target doesn't include usegas.h. However, the code is still needed, so the HAVE_GNU_AS form is now used. * Uses of usegas.h in various powerpc*-*-* configurations in gcc/config.gcc. Those make no difference since USE_GAS isn't used in any of the affected files. Bootstrapped without regressions on i386-pc-solaris2.11 and sparc-sun-solaris2.11 (as/ld, gas/ld, and gas/gld configurations). 2025-11-18 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> gcc: * config/i386/sol2.h: Replace USE_GAS by HAVE_GNU_AS. Replace USE_GLD by HAVE_GNU_LD. * config/sol2.h: Likewise. * config/sparc/sol2.h: Likewise. * config/i386/i386.cc (i386_solaris_elf_named_section) [TARGET_SOLARIS]: Replace USE_GAS by HAVE_GNU_AS. * config/ia64/hpux.h: Likewise. * config.gcc: Remove usegas.h, usegld.h. * config/usegas.h: Remove. * config/usegld.h: Remove gcc/go: * gospec.cc (lang_specific_driver) [TARGET_SOLARIS]: Replace USE_GLD by HAVE_GNU_LD.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
