This patch dumps the final (merged) list of alias pairs. It also adds: - WAW and RAW versions of vect-alias-check-8.c - a "well-ordered" version of vect-alias-check-9.c (i.e. all reads before any writes) - a test with mixed steps in the same alias pair I also tweaked the test value in vect-alias-check-9.c so that the result was less likely to be accidentally correct if the alias isn't honoured. 2019-11-16 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-data-ref.c (dump_alias_pair): New function. (prune_runtime_alias_test_list): Use it to dump each merged alias pair. gcc/testsuite/ * gcc.dg/vect/vect-alias-check-8.c: Test for the RAW flag. * gcc.dg/vect/vect-alias-check-9.c: Test for the ARBITRARY flag. (TEST_VALUE): Use a higher value for early iterations. * gcc.dg/vect/vect-alias-check-14.c: New test. * gcc.dg/vect/vect-alias-check-15.c: Likewise. * gcc.dg/vect/vect-alias-check-16.c: Likewise. * gcc.dg/vect/vect-alias-check-17.c: Likewise.

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.
