Neon vector-tuple types can be passed in registers on function call and return - there is no need to generate a parallel rtx. This patch adds cases to detect vector-tuple modes and generates an appropriate register rtx. This change greatly improves code generated when passing Neon vector- tuple types between functions; many new test cases are added to defend these improvements. gcc/ChangeLog: 2021-10-07 Jonathan Wright <jonathan.wright@arm.com> * config/aarch64/aarch64.c (aarch64_function_value): Generate a register rtx for Neon vector-tuple modes. (aarch64_layout_arg): Likewise. gcc/testsuite/ChangeLog: * gcc.target/aarch64/vector_structure_intrinsics.c: New code generation tests. |

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.
