* nir: Tag entrypoint for easy recognition by nir_shader_get_entrypoint()Matt Turner2019-01-097-6/+30
| | | | | | | | We're going to have multiple functions, so nir_shader_get_entrypoint() needs to do something a little smarter. Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>
* nir: Rework nir_lower_constant_initializers() to handle functionsMatt Turner2019-01-091-34/+25
| | | | | | Previously it assumed that only a single function (the entrypoint) existed and attempted to lower constant initializers of shader outputs for each function, for instance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Will be used to convert the .glsl source file containing software fp64 routines to a .h file that can be included while building the compiler. This commit contains two squashed together: the first from Ian adding the utility (with the existing title), and the second from Dylan making the code both python2 and python3 compatible. This is somewhat modeled after the xxd utility that comes with Vim. Signed-off-by: Ian Romanick <[email protected]> xxd.py: Make python2 and 3 compatible This makes use of unicode_literals, so that undecorated strings are considered text (python2 unicode, python3 str) and not bytes in python2 and text in python3. It makes use of io.open, which provides python2 with python3's open behavior (it's an alias in python3), in particular support for the 't' and 'b' option. Finally, it decorates all of the string literals with the 'b' prefix, so that python interprets them as bytes. I've removed the stdin and stdout options, as python2 always requires these to be bytes, but python3 always treats them as text (there is a way to get at the underlying bytes buffer, but that's even more complexity), and makes the input files required arguments. In the meson we use the '@INPUT@' shorthand instead of listing each input, as meson will expand that to [prog_python, '@INPUT0@', @INPUT1@, ..., @OUTPUT@, ...]

| | | | | | | | | | | | | | | | | | | | | | | | | | | Otherwise we can end up with IR that looks like this: ( (declare (temporary ) vec4 f@8) (assign (xyzw) (var_ref f@8) (var_ref f) ) (call f16 ((swiz y (var_ref f@8) ))) (assign (xyzw) (var_ref f) (var_ref f@8) ) )) When we really need: (declare (temporary ) float inout_tmp) (assign (x) (var_ref inout_tmp) (swiz y (var_ref f) )) (call f16 ((var_ref inout_tmp) )) (assign (y) (var_ref f) (swiz y (swiz xxxx (var_ref inout_tmp) ))) (declare (temporary ) void void_var) The GLSL IR function inlining code seemed to produce correct code even without this but we need the correct IR for GLSL IR -> NIR to be able to understand whats going on.

* nir: rename global/local to private/function memoryKarol Herbst2019-01-0823-86/+86
| | | | | | | | | | | | | | | | | | the naming is a bit confusing no matter how you look at it. Within SPIR-V "global" memory is memory accessible from all threads. glsl "global" memory normally refers to shader thread private memory declared at global scope. As we already use "shared" for memory shared across all thrads of a work group the solution where everybody could be happy with is to rename "global" to "private" and use "global" later for memory usually stored within system accessible memory (be it VRAM or system RAM if keeping SVM in mind). glsl "local" memory is memory only accessible within a function, while SPIR-V "local" memory is memory accessible within the same workgroup. v2: rename local to function as well v3: rename vtn_variable_mode_local as well Signed-off-by: Karol Herbst <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>
