Subject: configure: add -Wno-pass-failed for libyuv
X-Git-Tag: v1.13.0-rc1~106
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d22e5a49e38a1749afdbff167dec81fb5061c5c6;p=libvpx

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
