Build a dynamic library for Slang

2017-07-19T18:27:23+00:00

- Change the `slang` project from a static library to a dynamic one - Add some details around `slang.h` to make sure DLL export stuff is working - Make the `slangc` executable use the dynamic library - Rename the `glslang` sub-project to `slang-glslang` and move it into the main source hierarchy - This reflects the fact that it isn't a stand-alone tool, and isn't in any way a standard binary of glslang, but rather just an artifact of how Slang uses glslang

Add a compile-time loop construct to Slang

2017-07-18T21:51:12+00:00

The basic syntax is: $for(i in Range(0,99)) { /* stuff goes here */ } Note that the exact form is very restrictive. All that you are allowed to change is `i`, `0`, `99` or `/* stuff goes here */`. As a tiny bit of syntax sugar, the following should work: $for(i in Range(99)) { /* stuff goes here */ } Note that the range given is half-open (C++ iterator `[begin,end)` style). Both the beginning and end of the range must be compile-time constant expressions that Slang knows how to constant-fold. The implementation will basically generate code for `/* stuff goes here */` N times, once for each value in the half-open range. Each time, the variable `i` will be replaced with a different compile-time-constant expression. While I was working on a test case for this, I also found that our build of glslang had an issue with resource limits, so I fixed that. Clients will need to build a new glslang to use the fix.

Don't use "auto locations" mode in glslang

2017-07-14T17:05:38+00:00

Fixes #88 The code was using `glslang::TShader::setAutoMapLocations` as a workaround for an old glslang issue, but apparently this mode has a bug where it ends up applying a `location` layout to the implicitly-created `gl_PerVertex` definition (which shouldn't be allowed). This change drops the call to `setAutoMapLocations` (and `setAutoMapBindings`) since it should no longer be required.

Add support for dumping intermediates for debugging.

2017-07-13T20:00:38+00:00

Calling: spSetDumpIntermedites(compileRequest, true); will set up a mode where Slang tries to dump every intermediate HLSL, GLSL, DXBC, SPIR-V, etc. file it generates. If SPIR-V or DXBC is requested then we also dump assembly of those. Right now the files are all named as `slang-.`, and get dropped in whatever the working directory is, but I'm open to ideas on how to improve that. Note: this change introduces a new binary interface to `glslang`, so pulling it requires an updated `glslang.dll`.
