Minor improvements to the %split/vec4 instruction.
2014-11-21 16:51:59 -08:00
663c79d4af
Add the %cmp/e instructions, and put them to use.
...
When testing for == and ===, there is no need to also calculate <,
so it makes sense to have a special instruction for these cases.
2014-11-21 16:45:27 -08:00

Also update some more instructions to more optimally work with
the vec4 stack.

c71ab5869a
vvp code generator try to generate condition flags directly.
...
When generating code for a condition expression, i.e. directly
before a %jmp/X statement, try to generate the result into the
flag bit without passing through the vec4 stack. For example, the
%cmpX/X instructions generate results into the flag bits, so it
makes no sense to push these bits into the vec4 stack then pop
them back into the flag bit. So try to handle this case.
2014-11-19 18:32:19 -08:00
04bdfbccee
Add %cmpi/s and %cmpi/u instructions for performance
...
