45ad58a903 Implement more correct integer op handling. 
In some cases we need to bitcast when dealing with int vs. uint.
SPIR-V allows inputs to be of different integer signedness, so we need
to deal with this somehow.

Add testing system to test SPIR-V assembly.
For now, test all possible combination for all major cases.

 - IAdd (which doesn't care about input type as long as they're equal)
 - SDiv/UDiv operations which case about input type.
 - Arith/Logical right shifts.
 - IEqual to test outputs to bvec, which shouldn't get output cast. Also
   tests casting in function-like calls.

8869a167d6 Drop --vulkan flag to test_shaders.py

78c9a80600 Make test_shaders.py more robust with out-of-tree builds. 
Previous assumed that test script was run from root folder.
This doesn't work with out-of-tree builds.

0b54291950 Merge pull request #3 from dneto0/add-cmake-support 
Add a CMakeLists.txt file for use by cmake, ctest

59d6898fd0 Add a CMakeLists.txt file for use by cmake, ctest 
This enables out-of-tree builds, and the use of other build tools.

This will not overwrite Makefile if you are building in the
source tree.  To use makefiles generated from CMake, you must
build out of the source tree.

Usage: If SPIRV-Cross source is in $SPIRV_CROSS_ROOT, then to
build with ninja in a different directory:

   cmake -G Ninja $SPIRV_CROSS_ROOT
   ninja

   # Run tests, if enabled
   ctest

Tests will be enabled if you have python3.

2d38c6e192 Fixups for struct-packing test. 
There seems to have been some changes to alignment in glslang here,
so workaround to verify that the other cases at least still work as expected.

dbee4e4346 Add support for Vulkan GLSL as output target. 
Mostly useful for debugging SPIR-V where it is useful to see the
"original" Vulkan GLSL constructs which created the SPIR-V.

4b8ed53974 Add Clang format. 
Reformats the entire codebase. Better to do it now than later.

Adds .clang-format and a convenience script format_all.sh which formats
everything automatically.

9d4b5c0c59 Use texel fetch instead of normalized sampling for subpass. 
Cleaner output code, and matches more directly to how subpass reads work.

7652c90802 Add support for separate samplers and textures. 
This will not really make sense for plain GLSL/ESSL target, but other
backends might want it and useful to have for debugging.
