Subject: x86_64-xlate.pl: new gas requires sign extention in lea instruction.
X-Git-Tag: OpenSSL-fips-2_0-rc1~1438
X-Git-Url: https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff_plain;h=10232bdc0e28b5417051942fe57fa14d17e104a6

x86_64-xlate.pl: new gas requires sign extention in lea instruction.
This resolves md5-x86_64.pl and sha1-x86_64.pl bugs, but without modifying
the code.
