--- Comment #8 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Alex Coplan <acop...@gcc.gnu.org>: https://gcc.gnu.org/g:8764e9a3fc43f1117db77d1f056b6c3f15a29db3 commit r11-2228-g8764e9a3fc43f1117db77d1f056b6c3f15a29db3 Author: Alex Coplan <alex.cop...@arm.com> Date: Mon Jul 20 16:15:29 2020 +0100 jit: Fix truncation of testsuite output [PR69435] This fixes a bug in jit.exp which causes the DejaGnu output of the libgccjit testsuite to be nondeterministically truncated. This bug was copied from DejaGnu's own implementation of the host_execute function. See the upstream bug report [0] where the maintainers point out that the regex patterns in host_execute should (but don't currently) explicitly match newlines to avoid relying on DejaGnu not reading more than one line of the output (which is not guaranteed). This should make it easier to test jit patches in the future, since it makes it possible to reliably compare the output of two jit.sum files (as with the other tests in GCC). [0] : https://debbugs.gnu.org/cgi/bugreport.cgi?bug=42399 gcc/testsuite/ PR jit/69435 * jit.dg/jit.exp (fixed_host_execute): Fix regex patterns to always explicitly match newlines.
