* Make sure source strings are terminated
The source strings may or may not have a null terminator. We need to
make sure we add one before outputting the source strings as we iterate
over the c-str looking for the null terminator.
* Review feedback
- Add ES 320 support
- Error out use of perprimitiveNV for non mesh/fragment shaders
- Error out use of mesh/task shaders w/o use of NV_mesh_shader
- Error out use of NV_mesh_shader for non task/mesh shaders
- Error out use of perviewNV for non mesh shaders
- Error out use of taskNV for non mesh/task shaders
- Add test case for mesh shader with ES 320 profile
std::stringstream has a measurable overhead for preprocessing - it
appears that operator<< does a tiny bit of extra work for appending
chars/strings and also can't be inlined in most cases on VS2015;
additionally, std::endl triggers a stream flush which also adds up.
Replacing this with std::string buffer gets the preprocessing time down
from 180ms to 135ms in one case, making it 1.33x faster.
Note that integer-to-string conversion is using std::to_string; in
theory this could be slower than sprintf or manual conversion, but I
haven't found these cases to affect preprocessing time in practice
(std::to_string would always use the short string buffer for
line/version numbers, and the number of calls is not too significant).
Adds command line options:
--invert-y
--iy
(synonyms) which invert position.Y on vertex shader output. Handles these cases:
* Direct single variable return
* Member of direct returned struct
* Single variable output parameter
* Member of struct output parameter
API:
// Enables position.Y output negation in vertex shader
void TShader::setInvertY(bool invert);
Fixes#1173
Addresses #928, #389, and 1st item in #976. Overlaps #916.
This had been dropped, when moving away from the old Win32 DLL model.
Issue: per-thread tear down for other threads.
Addresses step 4 of #976, overlaps #916.
For each pool, now, it is newed, remembered, and freed by the same entity,
rather than having a mix (thread finalize freeing current pool) that could
lead to double freeing of the same pool. It is quite rational and simple now.
This will enable reinstalling process and thread tear down.
Per feedback on PR #1111, this reverses the order of the parameters for the setShiftBinding API.
It is now:
void TShader::setShiftBindingForSet(TResourceType res, unsigned int base, unsigned int set);
This PR adds the ability to provide per-descriptor-set IO mapping shift
values. If a particular binding does not land into a per-set value,
then it falls back to the prior behavior (global shifts per resource class).
Because there were already 6 copies of many different methods and internal
variables and functions, and this PR would have added 6 more, a new API is
introduced to cut down on replication and present a cleaner interface.
For the global (non-set-specific) API, the old entry points still exist
for backward compatibility, but are phrased internally in terms of the
following.
// Resource type for IO resolver
enum TResourceType {
EResSampler,
EResTexture,
EResImage,
EResUbo,
EResSsbo,
EResUav,
EResCount
};
Methods on TShader:
void setShiftBinding(TResourceType res, unsigned int base);
void setShiftBindingForSet(TResourceType res, unsigned int set, unsigned int base);
The first method replaces the 6 prior entry points of various spellings, which
exist now in depreciated form. The second provides per-resource-set functionality.
Both accept an enum from the list above.
From the command line, the existing options can accept either a single shift value as
before, or a series of 1 or more [set offset] pairs. Both can be provided, as in:
... --stb 20 --stb 2 25 3 30 ...
which will use the offset 20 for anything except descriptor set 2 (which uses 25) and
3 (which uses 30).
Adds a transformation step to the post processing step.
Two modes are available:
1) keep
- Keeps samplers, textures and sampled textures as is
2) transform pure texture into sampled texture and remove pure samplers
- removes all pure samplers
- transforms all pure textures into its sampled counter part

Also, provides an option to auto-assign locations.
Existing tests use this option, to avoid the error message,
however, it is not fully implemented yet.
