Subject: Correct an Altivec configure think-o.
X-Git-Tag: svn/VALGRIND_3_12_0~71
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a57acb9be6c6138c4213674ca679c215eb852a55;p=thirdparty%2Fvalgrind.git

Correct an Altivec configure think-o.

An earlier change introduced a think-o in the altivec capability
check, allowing a false positive if the compiler supported altivec
but the hardware did not.

Resolves bug #368412 - False positive result for altivec capability check
Patch by Will Schmidt <will_schmidt@vnet.ibm.com>
