Subject: s390x: Fix disassembly of locfh/locfhr, update S390_MAX_MNEMONIC_LEN
X-Git-Tag: VALGRIND_3_24_0~84
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=67a2bb759a7c9c76fd6aa142bdb6fe342a5998e2;p=thirdparty%2Fvalgrind.git

s390x: Fix disassembly of locfh/locfhr, update S390_MAX_MNEMONIC_LEN

The length of the "longest mnemonic" for the s390x disassembler is
currently defined in s390_defs.h to be 8 characters, where in fact it
should be 9.  Update the constant to reflect that.

Also fix the disassembly of the instructions locfh and locfhr, changing
them from their current wrong representations `locgh' and `locghr'.
