 Synopsis: Legal intel instructions being flagged as illegal

 State-Changed-From-To: open->closed
 State-Changed-By: zack
 State-Changed-When: Tue Oct 22 13:20:42 2002
 State-Changed-Why:
     GCC does not attempt to interpret the text of an asm() statement, beyond
 processing %-substitutions for operands.  The error message you quoted came
 from the assembler.

     The instruction mnemonics "pushfd" and "popfd" are valid only in Intel
 syntax.  In its default mode, GAS uses AT&T syntax, in which these opcodes
 are spelled "pushf" and "popf" respectively.  You can either change your
 code to use these, or (with sufficiently recent versions of GCC and GAS) you
 can use the -masm=intel command line switch.
