d21baed6bc HLSL: Flatten whole-struct assigns and returns when targeting flattened I/O structs. 2016-09-16 03:20:03 -06:00
John Kessenich
f8e494c18c HLSL: Flatten all input/output structs, regardless of stage. 
This is needed because an output structure can contain embedded built-ins
(like SV_Position) which should not get locations assigned.

7dc630f3da HLSL: Flatten a return struct from an entry point and assign locations after flattening. 
Locations now get assigned in order, but skipping built-ins, which can be
done post flattening.

7f702124ec HLSL: return correct error when HLSL parsing fails. 
At least partially addresses issue #510.

deb4940c17 HLSL: Register all entry-point in/out as part of the interface. 
This makes the interface be invariant, whether or not individual
variables are used.

cd0a78a0d9 HLSL: Flatten vertex input and fragment output structures.

of the fragment stage.

7735b94403 HLSL Non-Functional: Move to more robust capturing of postDecls into a qualifier. 
This will prevent a possible future defect of thinking the type can be changed,
where there is a code path today that would drop that change.

4bf7155051 SPV: Flatten structs for copy when they are GLSL type aliases. 
Addresses issue #304 and issue #307 by replacing unmatched type OpStores with
per-member copies. Covers assignment statements and most argument passing, but
does not yet cover r-value-based argument passing.

f2b7f3353b SPV: Tighten up number of struct-types declared based on decoration. 
Takes some pressure off of issue #304.
Structures don't inherit locations and then explicitly decorate
members with them, so removed this reason to have another instance
of a structure type.

5e56423046 Front-ends: Remove now defunct afterEOF and related, use scanner's instead. 
Code using atEndOfFile was dead, instead do something useful with
the scanners atEndOfInput().  This allows a better error message
for early termination of cascading errors.

830b0cc98b HLSL: Start location numbering with the entry-point return value. 
Also, increment location numbers by the size of the objects.

a05d8b5604 HLSL: Remove recent change to put locations on SV_TARGET*. 
This put locations on members of structures, which is not allowed
in either AST or SPIR-V.

This was caught by asserts in the debug build.

6a70eb7161 HLSL: Emulate write-to-output on return-from-entry-point, for return value. 
This fixes issue #487 and #480.
It also correctly handles output parameters from the entry point.

81cd764b5f Non-functional: Add some missing const, related to signature selection. 2016-08-26 14:01:43 -06:00
John Kessenich
e3f2c8f98a HLSL: Include shape-changing conversions in overloaded signature selection. 
This also enables vecN -> vec1 shape conversions for all places doing shape
conversions.

For signature selection, makes shape changes worse than any other comparison
when deciding what conversions are better than others.

90dd70f752 HLSL: Allow arbitrary baseType -> baseType conversion of calling arguments. 
This also puts a stake in the ground as to which is better when selection
from multiple signatures.

fcc0aa3b64 HLSL: Switch to generic selector, but using GLSL #version 400 rules. 
Next step is to modify for HLSL rules.

32c169dbdf Front-end: Warn for likely missed change in default precisions. 
This is part of the change to have desktop shaders respect precision
qualifiers on Vulkan, but since the defaults are all highp, and that's
different from ES fragment shaders, detect likely cases and warn about
them (but being careful to not be too noisy if it's unlikely to be a
problem).

4d535640e4 Front-End: Non-ES trigger for processing precision qualifiers.

precision qualifiers other than whether the profile is es.

9f9bad09b4 PP: Add missing atoms that effect -E mode. 
When preprocessing only, some tokens were emitted as <bad token>.
This fixes them to preserve their original content.

f6640761c4 Front-end: Implement 2nd task of issue #400; precision of result and operation. 
From the ES spec + Bugzilla 15931 and GL_KHR_vulkan_glsl:
- Update precision qualifiers for all built-in function prototypes.
- Implement the new algorithm used to distinguish built-in function
  operation precisions from result precisions.
Also add tracking of separate result and operation precisions, and
use that in generating SPIR-V.
(SPIR-V cares about precision of operation, while the front-end
cares about precision of result, for propagation.)

11e1a073f3 PP: Fix issue #407; handle empty identifier. 
The sequence

  #define m()

against a string of 0 size as well as the existing protect
against a null string.

73d4fb5bc5 PP: Fix issue #408: # as last character in macro. 
This would look ahead for a second #, for token pasting, and if not
found, backup one token.  This is fine, unless at the end of line,
which would backup the #, rather than the look ahead.
