Subject: libstdc++: Fix DRIVEROPTS and TESTFLAGS processing
X-Git-Tag: upstream/12.2.0~9881
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b27ea896dd73a9065771e3e8c2fcdc69af80e186;p=platform%2Fupstream%2Fgcc.git

libstdc++: Fix DRIVEROPTS and TESTFLAGS processing

libstdc++-v3/ChangeLog:

	* testsuite/experimental/simd/generate_makefile.sh: Use
	different variables internally than documented for user
	overrides. This makes internal append/prepend work as intended.
