Thumb1 cannot support asm-flags currently, because we don't expose the flags register to the compiler. Disable the support for that case. Adjust the asm-flag-6 test for aarch64 ilp32 correctness. gcc/ * config/arm/arm-c.c (arm_cpu_builtins): Use def_or_undef_macro to define __GCC_ASM_FLAG_OUTPUTS__. * config/arm/arm.c (thumb1_md_asm_adjust): New function. (arm_option_params_internal): Swap out targetm.md_asm_adjust depending on TARGET_THUMB1. * doc/extend.texi (FlagOutputOperands): Document thumb1 restriction. gcc/testsuite/ * testsuite/gcc.target/arm/asm-flag-3.c: Skip for thumb1. * testsuite/gcc.target/arm/asm-flag-5.c: Likewise. * testsuite/gcc.target/arm/asm-flag-6.c: Likewise. * testsuite/gcc.target/arm/asm-flag-4.c: New test. * testsuite/gcc.target/aarch64/asm-flag-6.c: Use %w for asm inputs to cmp instruction for ILP32.

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.
