Subject: [PATCH] target/i386: correctly mask SSE4a bit indices in register
|
|
operands
|
|
|
|
SSE4a instructions EXTRQ and INSERTQ have two bit index operands, that can be
|
|
immediates or taken from an XMM register. In both cases, the fields are
|
|
6-bit wide and the top two bits in the byte are ignored. translate.c is
|
|
doing that correctly for the immediate case, but not for the XMM case, so
|
|
fix it.
