Libatomic builds a few functions for Arm with an explicit -march option. This option does not specify an FPU, which can lead to problems when targeting a hard-float or softfp environment since the architecture appears to be incompatible with the selected ABI. The fix is simple enough, just add +fp (the minimum floating point option) to the architecture. We don't use anything from the FP architecture, so it shouldn't really change anything; and if we are building for -mfloat-abi=soft the canonicalization process will remove the unnecessary fp attributes anyway. * Makefile.am: (IFUNC_OPTIONS): Set the architecture to -march=armv7-a+fp on Linux/Arm. * Makefile.in: Regenerated.

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.
