2359bd0a1d SPV: Fix extra operands when using the "struct" form of a built-in taking an 'out' param. 2015-12-06 19:29:11 -07:00

e721f49dbd SPV: Distinguish between std140 and std430 layouts, and correctly use alignments as the base for strides. 2015-12-06 19:17:49 -07:00

989df85dcd Array-sizing bug fix: multiple array initializers of different size in the same declaration. 
Handles the case of
    float[] x = float[] (1.0, 2.0, 3.0),
            y = float[] (1.0, 2.0, 3.0, 4.0);
where a shallow copy of the type arrayness from the left-most float[]
was getting used twice.

b5c046e58b Front-end: Fix missing tessellation shader built-in qualifiers. 
The gl_in array has a special path due to context-specific
gl_MaxPatchVertices, making the code out of order for tagging built-ins.
This commit moves the tagging to the correct location.
This also fixes issue #80.

eb505e4262 Allow future keywords to be accessed as members in a struct. 
This fixes a bug where a token that could be a keyword in one version
is not a keyword in another version, but treated like a non-member after
a "." dereference.

6373574b13 Front-end: Fix: Cubemap arrays only use 3-component coord when accessed as an image. 
4 components are needed when used a texture, but not an image, which multiplies
layers and faces into the same coordinate.  This fixes it from using 4 everywhere,
to only using 4 for textures and 3 for images.

7355eebb18 SPV legacy texturing: Smear result of Op*Dref* up to a vector to match 
the expectations of old GLSL shadow*() lookups.

e770b3e6cf SPV return from main: Simplify a legacy design such returns are not jumps to exit block. 
Structured control-flow rules allow leaving the middle of a construct through
a return, but not through a jump to a block that does a return.

Addresses issue #58.

5f5b205ce9 Bump up layout(location) limit from 62 to 4094, to handle bigger uniform locations. 2015-09-13 21:03:33 -06:00

fa668dad99 SPV: Reduce spurious type generation by removing intermediate types in the middle of access chains. 
This generally simplifies access chain generation, with far fewer  type conversions.
It is particularly important to future SPIR-V changes where there is less aggregate
type uniqueness due to carrying different layout information with the type.

fc51d284aa Backward incompatible: Turn on PureOperatorBuiltins: use only enum-based built-in functions in the AST. 
If this breaks your AST consumer, best is to modify it to test
against the enum values instead of doing string comparisons on
built-in function names.  This is the reason the change was made.

If you need the old behavior, you should be able to get it back by changing
PureOperatorBuiltins to be false instead of true.  This path will work for
a while, but is marked deprecated.

Also, the old behavior is tagged as release 2.4.

ef676b0a59 Front-end "pure" built-in TOperator: Finish adding full support, but still turned off. 
This is to avoid all need to do text comparison of built-in function names
when consuming the AST.  All built-in functions get enumerants.

Will want to turn on soon.  See PureOperatorBuiltins.  See issue #8.
