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.

For example, for the two (FAIL, XFAIL)
'gcc/testsuite/lib/gcc-dg.exp:gcc-dg-test-1' cases:
-FAIL: g++.dg/modules/xtreme-header-3_a.H -std=c++17 (internal compiler error)
+FAIL: g++.dg/modules/xtreme-header-3_a.H -std=c++17 (internal compiler error: tree check: expected var_decl or function_decl or field_decl or type_decl or concept_decl or template_decl, have namespace_decl in get_merge_kind, at cp/module.cc:10072)
-FAIL: gfortran.dg/gomp/clauses-1.f90 -O (internal compiler error)
+FAIL: gfortran.dg/gomp/clauses-1.f90 -O (internal compiler error: Segmentation fault)
-XFAIL: c-c++-common/goacc/kernels-decompose-ice-1.c (internal compiler error)
+XFAIL: c-c++-common/goacc/kernels-decompose-ice-1.c (internal compiler error: in lower_omp_target, at omp-low.c:13147)

That allows for more easily spotting when during development you're trading one
ICE for another.
gcc/testsuite/
* lib/fortran-torture.exp (fortran-torture-compile)
(fortran-torture-execute): Be more informative for ICEs.
* lib/gcc-defs.exp (${tool}_check_compile): Likewise.
* lib/gcc-dg.exp (gcc-dg-test-1): Likewise.
* lib/go-torture.exp (go-torture-compile, go-torture-execute):
Likewise.
