* python: Explicitly add the 'L' suffix on Python 3Mathieu Bridon2018-08-011-1/+10
| | | | | | | | | | | | | | | Python 2 had two integer types: int and long. Python 3 dropped the latter, as it made the int type automatically support bigger numbers. As a result, Python 3 lost the 'L' suffix on integer litterals. This probably doesn't make much difference when compiling the generated C code, but adding it explicitly means that both Python 2 and 3 generate the exact same C code anyway, which makes it easier to compare and check for discrepencies when moving to Python 3.

* python: Don't abuse hex()Mathieu Bridon2018-08-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hex() builtin returns a string containing the hexa-decimal representation of an integer. When the argument is not an integer, then the function calls that object's __hex__() method, if one is defined. That method is supposed to return a string. While that's not explicitly documented, that string is supposed to be a valid hexa-decimal representation for a number. Python 2 doesn't enforce this though, which is why we got away with returning things like 'NIR_TRUE' which are not numbers. In Python 3, the hex() builtin instead calls an object's __index__() method, which itself must return an integer. That integer is then automatically converted to a string with its hexa-decimal representation by the rest of the hex() function. As a result, we really can't make this compatible with Python 3 as it is. The solution is to stop using the hex() builtin, and instead use a hex() object method, which can return whatever we want, in Python 2 and 3.

| | | | | | | | | | | | | | | | | | | | | | | | | | | From SPIR-V 1.0 spec, section 3.20, "Decoration": "Stream Apply to an object or a member of a structure type. Indicates the stream number to put an output on." Note the "or", so that means that it is allowed for both a full struct or a membef or a struct (although the wording is not really ideal, and somewhat error-prone, imho). We found this with some Geometry Streams tests for ARB_gl_spirv, where the full gl_PerVertex is assigned Stream 0 (default value on OpenGL for gl_PerVertex). So this commit allows structs to have this Decoration, and sets the stream at the nir variable if needed.

| | | | | | | | | | | | | | | | | | Until now, we had separate passes for lowering gl_PatchVerticesIn to a statically known constant (for TES inputs when linked against a TCS), and a uniform in the other cases. Annoyingly, one had to be run before nir_lower_system_values, and the other afterward. This simplified the passes, but made life painful for the callers. This patch combines both into a single pass. If you give it a non-zero static count, it uses that. If you give it Mesa state slots, it turns it back into a built-in uniform. Otherwise, it does nothing.
