- hlsl.struct.frag variable changed to static, assignment replacd.
- Created new low level functions addBinaryNode and addUnaryNode. These are
used by higher level functions such as addAssignment, and do not do any
argument promotion or conversion of any sort.
- Two functions above are now used in RWTexture lvalue conversions. Also,
other direction creations of unary or binary nodes now use them, e.g, addIndex.
This cleans up some existing code.
- removed handling of EOpVectorTimesScalar from promote()
- removed comment from ParseHelper.cpp
This commit splits lValueErrorCheck into machine dependent and independent
parts. The GLSL form in TParseContext inherits from and invokes the
machine dependent part in TParseContextBase. The base form checks language
independent things. This split does not change the set of errors tested
for: the test results are identical.
The new base class interface is now used from the HLSL FE to test lvalues.
There was one test diff due to this, where the test was writing to a uniform.
It still does the same indirections, but does not attempt a uniform write.
