If we compile the openacc testcase with -fopenacc -O2, we run into a SIGSEGV or assert. The root cause for this is that pass_thread_jumps breaks the invariant that OACC_FORK and OACC_JOIN mark the start and end of a single-entry-single-exit region. Fix this by bailing out when encountering an IFN_UNIQUE in thread_jumps::profitable_jump_thread_path. Bootstrapped and reg-tested on x86_64. Build and reg-tested libgomp on x86_64 with nvptx accelerator. 2019-06-15 Tom de Vries <tdevries@suse.de> PR tree-optimization/90009 * tree-ssa-threadbackward.c (thread_jumps::profitable_jump_thread_path): Return NULL if bb contains IFN_UNIQUE. * testsuite/libgomp.oacc-c-c++-common/pr90009.c: New test.

README
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.
