1a18739650 Fix ExtInst parsing: no IdRef* at end 
The operands following the extended instruction literal
number are determined by the extended instruction itself.
So drop the zero-or-more IdRef pattern at the end of OpExtInst.

It's arguable whether this should actually be a grammar fix.  I've
chosen to patch this in SPIRV-Tools instead of in the grammar file.

Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/233

Also fix two test cases for OpenCL extended instructions.  These
errors of supplying too many operands are now detected.

552d319962 Make directories more safely. 
Avoid a race on check-for-dir vs. make-dir
when running the inc-file generation script concurrently.

489786465a Grammar update: OpPhi now uses PairIdRefIdRef as the last operand. 2016-04-13 13:43:44 -04:00

11636fb100 Update the core grammar. 
* IdType is renamed to IdResultType.
* version is splitted into major_version and minor_version.
* Seperate Scope and IdScope operand kinds. Same for MemorySemantics.

469f0e8fd5 Make paths to grammar output files 
The directory for a grammar output file will be created if
it doesn't already exist.

This is required to make the Android.mk build work.

4f293b7139 Use the JSON grammar file to generate various info tables. 
This patch uses a Python script to parse the JSON grammar file to
generate the opcode table and operand kind tables.

Now we don't need to do the post-processing (from OperandClass
to spv_operand_type_t) and copying of the opcode info table is
not required anymore!
