[Valgrind-users] BUG: smsw instruction not supported

[Mike G. <mi...@ac...>]

Hi,

 I have a program that uses the smsw instruction (for the curious, I want to
test if FXSAVE is emulated by the processor). Valgrind quits with the following
message when it hits this instruction:

  "disInstr: unhandled instruction bytes: 0x66 0xF 0x1 0xE0".

 Those instruction bytes are equivalent to "smsw ax" in assembly.

Cheers,
--Mike
