AArch64 passes the "not profitable" test because it treats vec_construct as having a high-enough cost. This means that we can try other vector modes, which in turn causes "BB vectorization with gaps at the end of a load is not supported" to be printed more than once. The number of times that we print the message doesn't seem important, so the patch converts it to a plain scan-tree-dump. gcc/testsuite/ * gcc.dg/vect/bb-slp-pr68892.c: Don't XFAIL the profitability test for aarch64*-*-*. Allow the "BB vectorization with gaps" message to be printed more than once.
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.
