81a63f1de0 Add conversion folding when the source is a constant. 
This change adds unary conversion folding when the source is a constant.
This fixes an ISV issue whereby:

```
const float16_t f = float16_t(42.0);
```

Wouldn't compile because the conversion operator would always produce an
EvqTemporary when it could have produced an EvqConst.

I've also added a test case that proves out that all basic-type to
basic-type conversions work.

adba7dfc68 ParseHelper: assign global XfbBuffer to a block missing it 
If a block has assigned a XfbOffset it is assumed that it would
inherit the current global XfbBuffer. This commit fixes two use cases:

1) Getting the members of a Block with a XfbOffset to be assigned an
   offset, as explained on GLSL 4.60 spec, section "4.4.2 Output
   Layout Qualifiers", subsection "Transform Feedback Layout
   Qualifiers".

2) Compute properly an error on overlapping ranges if a block is
   assigned a XfbOffset and one of it members is assigned a explicit
   one. This gets working because when the members of a block get
   assigned a Offset/Buffer at fixBlockXfbOffsets, then the block is
   deassigned the Offsets, so ranges are computed only with the block
   members.

BTW, this is already done when redeclaring block builtins.

Fixes #1535

Merge pull request #1557 from nicebyte/spec-const-decorations 
Add names for composite spec constants in SPIR-V
 2018-11-02 10:23:22 -06:00
Grigory Dzhavadyan
4c9876b34c Add names for composite constants in SPIR-V 
Consider the following code:

    layout(constant_id=0) const int Y = 1;
    layout(constant_id=1) const int Z = 2;
    layout(constant_id=3) const int X = Y + Z;

Previously, it would produce SPIR-V decorations like this:

    Decorate 21(Y) SpecId 1
    Decorate 22 SpecId 3
    Decorate 33(Z) SpecId 0

This seems inaccurate, since the spec constant `X` that is dependent on
the two others did not get a name in the SPIR-V decorations. This behavior
may potentially negatively affect shader introspection capabilities.

This change alters the behavior to always add a name, which results in the code
above producing the following decorations:

    Decorate 21(Y) SpecId 1
    Decorate 22(X) SpecId 3
    Decorate 33(Z) SpecId 0

af8c1bdb16 ParseHelper: assign xfb_offset for struct members too 
If the out variable is a struct type, with a xfb_offset explicitly
assigned, the members need to get their xfb_offset assigned. This is
specially relevant, as we cannot use layout qualifiers on struct
members.
