Subject: configure: add -Wno-pass-failed for libyuv
X-Git-Tag: accepted/tizen/7.0/unified/20240521.012539~1^2~442
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d22e5a49e38a1749afdbff167dec81fb5061c5c6;p=platform%2Fupstream%2Flibvpx.git

configure: add -Wno-pass-failed for libyuv

with certain optimization flags or sanitizers enabled some code may fail
to vectorize:
third_party/libyuv/source/row_common.cc:3178:7: warning: loop not
vectorized: the optimizer was unable to perform the requested
transformation; the transformation might be disabled or specified as
part of an unsupported transformation ordering
[-Wpass-failed=transform-warning]

this was observed with integer/undefined sanitizers using clang 11/13
