Subject: Improve performance of smc-checks substantially, by:
X-Git-Tag: svn/VALGRIND_3_7_0~708
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ebfe3fcbe9c121c32c286a905a91fcf179faeee1;p=thirdparty%2Fvalgrind.git

Improve performance of smc-checks substantially, by:

(1) allowing translations to chase across BB boundaries, as in the
    non-smc-check case

(2) on 64-bit targets, do the checksumming with 64-bit loads
    instead of 32-bit ones.

(valgrind-side change, to match vex r2070)
