Subject: testsuite, asan: Avoid color in asan test output.
X-Git-Tag: releases/gcc-11.5.0~192
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=57596bb82e31d2dfdba2eb41c16e45a9bbeb38a7;p=thirdparty%2Fgcc.git

testsuite, asan: Avoid color in asan test output.

The presence of the color markers in the some of the asan tests
appears to confuse the dg-output matching (possibly a platform
TCL or termios bug) on some Darwin platforms.

Since the color is not being tested, switch it off (makes the log
files easier to read too).  This fixes a large number of spurious
test fails on AVX512 Darwin19.
