Consider the following code fragment:

Code:
; Assembly code emitted by HLA compiler
; Version 1.62 build 8707 (prototype)
; HLA compiler written by Randall Hyde
; FASM compatible output

             format  MS COFF


offset32     equ      
ptr        equ      


; Code begins here:



_HLAMain       :


            clflush byte ptr [L3_b__hla_+0] ;/* b */
            
    


FASM reports the following on the clflush instruction:

Code:
flat assembler  version 1.51
sse.asm [64]:
                clflush byte ptr [L3_b__hla_+0] ;/* b */
error: invalid size of operand.
Error returned by Assembler = 2

** error 2 ** deleting sse.exe
    


What am I doing wrong? Doc says the operand should be a byte operand.
Cheers,
Randy Hyde

Perhaps it need to be fixed - currently only operand without any size cast (absolute value or pure label) is accepted.
