On some of our arm targets, we get various -mfpu flags implicitly or explicitly passed to the compiler during test runs. The target options pushed in arm_neon.h that affect vmmlaq_s32 set isa_bit_neon, but the caller doesn't have that bit set, so arm_can_inline_p rejects the attempt to inline it, and the test fails. An explicit -mfpu=neon would address the compile problem, but cause the assembler to reject the generated code. So this patch adds -mfpu=auto to the test, overriding any implicit flags with the fpu implied by the arch. for gcc/testsuite/ChangeLog * gcc.target/arm/simd/vmmla_1.c: Pass -mfpu=auto.
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.
