With the patch I've posted today to fix up declare variant LTO handling, Tobias reported the patch still doesn't work, and there are two reasons for that. One is that when the base function is marked implicitly as declare target, we don't mark also implicitly the variants. I'll need to ask on omp-lang about details for that, but generally the compiler should do it some way. The other one is that the way base_delay is written, it will always call the usleep function, which is undesirable for nvptx. While the compiler will replace all direct calls to base_delay to nvptx_delay, the base_delay definition which calls usleep stays. 2020-10-28 Jakub Jelinek <jakub@redhat.com> Tom de Vries <tdevries@suse.de> PR testsuite/81690 * testsuite/libgomp.c/usleep.h: New file. * testsuite/libgomp.c/target-32.c: Include usleep.h.

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.
