Hi,
how can I address m32 source operand in inline assembler instruction like :
asm
   ...
   VBROADCASTSS m32, %xmm1;
   ...
end;
if I would like broadcast to %xmm10 single 32bit value at given memory 
location in:
const SI:single=0.1;
or
var SI:single=0.1;
Now I do it by (it works):
asm
   ...
   mov $SI, %rax;
   vbroadcastss (%rax), %xmm10;
   ...
end;
000000010020C4CF 48b8b043270001000000     movabs $0x1002743b0,%rax
000000010020C4D9 c462791810               vbroadcastss (%rax),%xmm10
Is there shorter - one liner - way? Something like:
   vbroadcastss SI, %xmm10; // compiles, but causes A/V when executed, 
because only low 32bit of address is taken (x86_64):
000000010020C4D9 c46279181425b0432700     vbroadcastss 0x2743b0,%xmm10
Thanks
-Laco.
