168e46fdf9 Use std::array in C++ backend. 
Deals better with composite construction in C++
and also fixes a few bugs in GLSL backend with array-of-arrays.

4739d16e98 Remove workaround for overly conservative memory barriers. 
This is now fixed in ESSL 3.10 backend of glslang, so we can remove the old workaround
of dropping full memory barriers.

Also fixes unrelated issue which newer glslang detects.

5ad4340976 Workaround case with identical structs but different types. 
With the current workarounds for SSBO type aliasing, we have no choice
but to look at OpName in order to figure this out properly.

2eb6037ff3 Remove type aliases when emitting buffer blocks in C++. 
C++ emits separate structs, which we must always emit properly.

6aa2007cba Deal better with OpName and OpMemberName which alias. 
OpName is only for debug information, so we must be very careful that
we do not reuse the same name for different variables.

This was previously done for local variables, but this commit extends
this to global variables as well.

f05373bdd1 Do not rely on OpName when finding OpTypeStruct aliases. 
SPIR-V can stamp out multiple variants of the same types to deal with
different offsets, layouts, array strides and so on in buffer blocks.

78e7615af6 Do not use flexible member arrays in C++. 
This is supported as compiler extensions, but we can be standards
compliant here, so use the classic workaround of having a single entry
array at the end of the structs instead.

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.

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
 2016-05-11 16:09:55 +02:00
David Neto
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.

backends might want it and useful to have for debugging.
