The assembler does not understand all the '+' options accepted by the compiler. The best solution to this is to simply strip the extensions and just pass the raw architecture or cpu name through to the assembler. We will use .arch and .arch_extension directives anyway to turn on or off individual features. We already do something similar for big.little combinations and this just extends this principle a bit further. This patch also fixes a possible bug by ensuring that the limited string copy is correctly NUL-terminated. While messing with this code I've also taken the opportunity to clean up the duplicate definitions of EXTRA_SPEC_FUNCTIONS by moving it outside of the ifdef wrapper. * config/arm/arm.h (BIG_LITTLE_SPEC): Delete macro. (ASM_REWRITE_SPEC_FUNCTIONS): New macro. (BIG_LITTLE_CPU_SPEC_FUNCTIONS): Delete macro. (ASM_CPU_SPEC): Rewrite. (MCPU_MTUNE_NATIVE_FUNCTIONS): New macro. (EXTRA_SPEC_FUNCTIONS): Move outside of ifdef. Use MCPU_MTUNE_NATIVE_FUNCTIONS and ASM_REWRITE_SPEC_FUNCTIONS. Remove reference to BIG_LITTLE_CPU_SPEC_FUNCTIONS. * common/config/arm/arm-common.c (arm_rewrite_selected_cpu): Ensure copied string is NUL-terminated. Also strip any characters prefixed by '+'. (arm_rewrite_selected_arch): New function. (arm_rewrite_march): New function. From-SVN: r249280 |

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.
