When AMD_conservative_depth is enabled:
* Let 'layout' be a token.
* Extend the production rule of layout_qualifier_id to process the tokens:
depth_any
depth_greater
depth_less
depth_unchanged
|

|
|
|
|
|
| |
Define macro GL_AMD_conservative_depth to 1 when its extension is
enabled.

Update the max_array_access of a global as functions that use that
global are pulled into the linked shader.
Fixes piglit test glsl-fs-implicit-array-size-01 and bugzilla #33219.

Previously only global arrays with implicit sizes would be patched.
This causes all arrays that are actually accessed to be sized.
Fixes piglit test glsl-fs-implicit-array-size-02.

The rvalue of the returned value can be NULL if the shader says
'return foo();' and foo() is a function that returns void.
Existing GLSL specs do *NOT* say that this is an error. The type of
the return value is void. If the return type of the function is also
void, then this should compile without error. I expect that future
versions of the GLSL spec will fix this (wink, wink, nudge, nudge).
Fixes piglit test glsl-1.10/compiler/expressions/return-01.vert and
bugzilla #33308.

We almost always want to simply steal; we only need to copy when copying
a token list (in which case we're already cloning stuff anyway).

|
|
|

These are already picked up by ir.h or glsl_types.h.

Improves the cases when:
* an explicit assignment references the read-only variable
* an 'out' or 'inout' function parameter references the read-only variable

The removed semantic check also exists in ast_type_specifier::hir(), which
is a more natural location for it.
The check verified that precision statements are applied only to types
float and int.

Do not assign a value to ast_type_specifier::precision when no precision
qualifier is present.
|
|
|
|
|
|
|
|
| |
Change default value to ast_precision_none, which denotes the absence of
a precision of a qualifier.
Previously, the default value was ast_precision_high. This made it
impossible to detect if a precision qualifier was present or not.

The check is performed only in GLSL versions >= 1.30.
From section 4.3.4 of the GLSL 1.30 spec:

... and 'centroid varying'. The check is performed only in GLSL
versions >= 1.30.
From page 29 (page 35 of the PDF) of the GLSL 1.30 spec:
"interpolation qualifiers may only precede the qualifiers in, centroid
in, out, or centroid out in a declaration. They do not apply to the
deprecated storage qualifiers varying or centroid varying."
Fixes Piglit test
spec/glsl-1.30/compiler/interpolation-qualifiers/smooth-varying-01.frag.

If an interpolation qualifier is present, then the method returns that
qualifier's string representation. For example, if the noperspective bit
is set, then it returns "noperspective".

'varying'
The specs that add 'layout' require the use of 'in' or 'out'.
However, a number of implementations, including Mesa, shipped several
of these extensions allowing the use of 'varying' and 'attribute'.
For these extensions only a warning is emitted.
This differs from the behavior of Mesa 7.10. Mesa 7.10 would only
accept 'attribute' with 'layout(location)'. This behavior was clearly
wrong. Rather than carrying the broken behavior forward, we're just
doing the correct thing.
This is related to (piglit) bugzilla #31804.
NOTE: This is a candidate for the 7.9 and 7.10 branches.

All of the extensions that add the 'layout' keyword also enable (and
required) the use of 'in' and 'out' with shader globals.

This isn't strictly necessary, but is definitely nicer.

You can now simply write (assign (xy) <lhs> <rhs>) instead of the
verbose (assign (constant bool (1)) (xy) <lhs> <rhs>).

This makes it unnecessary to pass _mesa_glsl_parse_state around
everywhere, making at least the prototypes a lot easier to read.
It's also more C++-ish than a pile of static C functions.

These used to be more complicated, but now are so simple there's no real
point in keeping them separate.

All of these functions used to take s_list pointers so they wouldn't all
need SX_AS_LIST conversions and error checking. However, the new
pattern matcher conveniently does this for us in one centralized place.
So there's no need to insist on s_list. Switching to s_expression saves
a bit of code and is somewhat cleaner.
|
| |
| |
| |
| |
| | |
Most code now relies on the pattern matcher rather than this function,
and for the only remaining case, not using this saves an iteration.

Previously, the IR reader was riddled with code that:
1. Checked for the right number of list elements (via a linked list walk)
2. Retrieved references to each component (via ->next->next pointers)
3. Downcasted as necessary to make sure that each sub-component was the
right type (i.e. symbol, int, list).
4. Checking that the tag (i.e. "declare") was correct.
This was all very ad-hoc and a bit ugly. Error checking had to be done
at both steps 1, 3, and 4. Most code didn't even check the tag, relying
on the caller to do so. Not all callers did.
The new pattern matching module performs the whole process in a single
straightforward function call, resulting in shorter, more readable code.
Unfortunately, MSVC does not support C99-style anonymous arrays, so the
pattern must be declared outside of the match call.
