Subject: Regtest: fix build of none crc32 x86
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c0efe57f42aef9fb1119cc7b80966bca34f75724;p=thirdparty%2Fvalgrind.git

Regtest: fix build of none crc32 x86

The 32bit opcode variant needs an explicit l suffix for clang.

The test is still failing due the the flags mask/printf.

With clang, in gdb jusrt before the crc32 opcode rthe flags are

eflags         0x200296            [ PF AF SF IF ID ]

but with gcc

eflags         0x200202            [ IF ID ]

AF and SF need to be masked. It seems to work without masking PF,
not sure why, need to look at that a bit more.
