* intel/compiler: Rearrange code to avoid future problemsMatt Turner2019-01-091-3/+4
| | | | | | | | A follow on commit will move nr to the same union as the immediate data, so we should assert these invariants before we overwrite the nr field. Reviewed-by: Kenneth Graunke <[email protected]>
* intel/compiler: Avoid false positive assertionsMatt Turner2019-01-091-6/+6
| | | | | | | | | | | A follow on patch will move the 'nr' field to the union containing the immediate field, so prepare by checking that we're only testing these assertions if the .file is correct. The assertions with != ARF were kind of silly to begin with because the <128 check is specifically only for things in the GRF. Reviewed-by: Kenneth Graunke <[email protected]>

* nir: Unset metadata debug bit if no progress madeMatt Turner2019-01-0922-12/+115
| | | | | | | | | | | | | | | | | | | | | NIR metadata validation verifies that the debug bit was unset (by a call to nir_metadata_preserve) if a NIR optimization pass made progress on the shader. With the expectation that the NIR shader consists of only a single main function, it has been safe to call nir_metadata_preserve() iff progress was made. However, most optimization passes calculate progress per-function and then return the union of those calculations. In the case that an optimization pass makes progress only on a subset of the functions in the shader metadata validation will detect the debug bit is still set on any unchanged functions resulting in a failed assertion. This patch offers a quick solution (short of a larger scale refactoring which I do not wish to undertake as part of this series) that simply unsets the debug bit on unchanged functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
