Subject: If we're doing an estimation operation, arrange to zap the bottom byte
X-Git-Tag: svn/VALGRIND_3_1_0~22
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=51020ef2a0201dfb0cd0ccf03225054637ef3d29;p=thirdparty%2Fvalgrind.git

If we're doing an estimation operation, arrange to zap the bottom byte
of the result as it's basically garbage, and differs between cpus.
