Converted a second project to use fasmg calm from fasm1 this evening.

I have this really old scalar product calculation function that I thought worked and has this instruction:

Code:
haddpd xmm0, xmm0
    


The message on assembling is:

Code:
flat assembler  version g.iveex
Includes.inc [29] Tensors.inc [240]:
        haddpd xmm0, xmm0
Processed: haddpd xmm0, xmm0
Error: illegal instruction.    


Is this correct? I'm not using this now and am just commenting it out. I guess it makes sense that the same register can't be used twice, but I just stumbled on this thread which has xmm1 as both operands:

(See Leibniz Theory of Pi (calculates Pi) uses SSE2/3 section)
https://board.flatassembler.net/topic.php?p=56115

With this commented out, this entire project assembles successfully also, just had to change the struc blocks to remove the curly braces and include label . mostly.

HADDPD is an SSE3 instruction, you need to include 'ext/sse3.inc' to have it available.

The "illegal instruction" is a legacy message inherited from fasm 1, which in turn inherited it from TASM. It simply means that no instruction with such name has been defined.

Oh, cool! Confirmed works:

Code:
flat assembler  version g.iveex
4 passes, 3.1 seconds, 259922 bytes.
