38b4db48f9 Fix #1983: __ is okay starting with ES 300, rather than 310. 2019-11-23 01:29:02 -07:00

71c100d7c0 GLSL output: Removed fixed-size buffer; fixes #769.
Makes some white-space differences in most output, plus a few cases
where more could have been put out but was cut short by the previous
fix-sized buffer.

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.)

f5dcdf0123 Front-end: Don't lower precision of bit operations taking highp inputs.
See issue #350 for detail.  This may be an ESSL specification issue.

1189a7bc4a Make double underscore "__" an error for ES 300, but a warning for 310.
The 310 spec (and desktop specs) have clarified this is a waring, not an
error, but 300 tests still expect an error.

09388459a8 glslang: Correct global precision qualifiers to make the qualifier global instead of temp (local).

8b37b04ecc glslang AST output: include global vs. temp (local) in the printed output. This only effects test results, but a future check-in is going to fix some globals.

cf0206c341 Restore r26245 and all tests and test results since 4/1:
r26245: Remove "not yet complete" warning for versions 130 and 140, after tidying up a bit and adding tests.  Token pasting is the only known missing feature, and gives its own message now on use.

5134b9cf57 Track what ins/outs/uniforms are used, so that errors like "declare after use" or "can't use both XXX and YYY" can be issued. So far, used this for invariant, gl_FragColor et. al., and gl_FragCoord use before redeclaration.
Also made all tests in testlist include linker tests.

f2ee3dd46a Add full support for uniforms with initializers, including intra-stage link validation of aggregate constant initializers.
This included 
 - encapsulating aggregate constants
 - removal of constant-aggregate comparison algorithms, instead using a flattened and direct std::vector comparison
 - adding structure type comparison for independently declared structures that still might match types

337dbc7d8c Add basic intra-stage linking validation for matching types and qualification of uniforms/ins/outs/globals, function body duplication, and mixing ES/non-ES shaders.
Still need to handle arrays and built-in redeclarations, and many more rules, but this puts the basics in place.
