Hello,

Using FASM 1.52 I get an error with the following instruction:

movsldup xmm0,xmm0

It doesn't matter which registers I use but assembles OK if I use:

movsldup xmm0,[esi]

Has anyone else had this problem?

Cheers,
Michael Gallagher

It's a bug - thanks for the report, the fix will be included in the next relase.

If you cannot wait, you can fix it yourself. In X86.INC file find the "sse_xmmreg_xmmreg" label, you should see the following code there:
Code:
      sse_xmmreg_xmmreg:
        cmp     [extended_code],12h
        je      invalid_operand
        cmp     [extended_code],16h
        je      invalid_operand    

Add there the two instructions after the "sse_xmmreg_xmmreg" label:
Code:
      sse_xmmreg_xmmreg:
        cmp     [mmx_prefix],66h
        jne     sse_xmmreg_xmmreg_ok
        cmp     [extended_code],12h
        je      invalid_operand
        cmp     [extended_code],16h
        je      invalid_operand
