Hi,
tgsi.rst currently reads:
.. opcode:: RET - Subroutine Call Return
pc = pop()
Potential restrictions:
* Only occurs at end of function.
Also, currently the glsl compiler happily generates code that ends up as
a TGSI shader that has RET in the middle of a function. ie it seems that
"potential restriction" isn't true at the moment.
Should that restriction be removed from tgsi.rst?
Or do you plan to change the glsl compiler or the module that transforms
the glsl compiler's output to TGSI so that RET will only be emitted at
the end of a function?
... or maybe I'm misinterpreting the spec?
The spec is wrong. RET may appear anywhere in a subroutine. Feel
free to fix this in the spec.
