Subject: arm64: get_Dwarf_Reg: at least handle the case of requesting XSP
X-Git-Tag: svn/VALGRIND_3_10_0~274
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=b8805a006b0181fc14cc286cf02cc26a1b605ea4;p=thirdparty%2Fvalgrind.git

arm64: get_Dwarf_Reg: at least handle the case of requesting XSP
instead of failing.  This makes some of the memcheck/tests/varinfo*
tests work somewhat correctly on arm64-linux.
