b5db60297a Workaround lack of alignas on MSVC 2013. 2019-04-09 15:09:44 +02:00

a489ba7fd1 Reduce pressure on global allocation. 
- Replace ostringstream with custom implementation.
  ~30% performance uplift on vector-shuffle-oom test.
  Allocations are measurably reduced in Valgrind.

- Replace std::vector with SmallVector.
  Classic malloc optimization, small vectors are backed by inline data.
  ~ 7-8% gain on vector-shuffle-oom on GCC 8 on Linux.

- Use an object pool for IVariant type.
  We generally allocate a lot of SPIR* objects. We can amortize these
  allocations neatly by pooling them.

- ~15% overall uplift on ./test_shaders.py --iterations 10000 shaders/.

c60b9a1e96 CLI: Make --iterations more useful. 
Add a basic benchmarking mode to test_shaders.py.
We cannot safely just call compile() in a loop. Do the full pipeline for
each iteration.

MSL: Fix OpLoad of array which is forced to a temporary.
 2019-04-09 15:08:53 +02:00
Hans-Kristian Arntzen
23db744e35 Deal with case where we need to emit SpvImplArrayCopy late. 
We cannot deduce if OpLoad needs ArrayCopy templates early since it's
heavily context dependent, and we might only know on 3rd iteration of
the compile loop.

Detect invalid DoWhileLoop early.
 2019-04-05 14:03:06 +02:00
Hans-Kristian Arntzen
317144a59c Detect invalid DoWhileLoop early. 
We had a bug where error conditions in DoWhileLoop emit path would not
detect that statements were being emitted due to the masking behavior
which happens when force_recompile is true. Fix this.

Also, refactor force_recompile into member functions so we can properly
break on any situation where this is set, without having to rely on
watchpoints in debuggers.

diverging use at the image variable level, not just expression level.

Add an option to override the namespace used for spirv_cross.
 2019-03-29 11:29:48 +01:00
Hans-Kristian Arntzen
9b92e68d71 Add an option to override the namespace used for spirv_cross. 
This is a pragmatic trick to avoid symbol collision where a project
links against SPIRV-Cross statically, while linking to other projects
which also use SPIRV-Cross statically. We can end up with very awkward
symbol collisions which can resolve themselves silently because
SPIRV-Cross is pulled in as necessary. To fix this, we must use
different symbols and embed two copies of SPIRV-Cross in this scenario,
now with different namespaces, which in turn leads to different symbols.

c48702d8c2 Fix crash when backend.int16_t_literal_suffix set to null. 
The design of backend.int16_t_literal_suffix and backend.uint16_t_literal_suffix
allows them to be set to null, but that was not always tested for.
I have removed the expectation that they can be null and set
backend.int16_t_literal_suffix to "" when no suffix is needed.
That has the same effect, and seemed to be a more usable and defensive approach.

0909975655 MSL: Declare gl_WorkGroupSize constant with [[maybe_unused]]. 
Avoids ugly warnings on nearly every compute shader.
We could do analysis to detect whether we need to emit this constant,
but it's a bit tedious to figure out if an OpConstantComponent is
actually used by opcodes, so just make it simple.

Allow user to disable individual backends.
Disallow this for CLI builds for now, but should be useful for
library-only builds, and particularly for C API.

eeb3f24991 Properly deal with sign-dependent GLSL opcodes. 
The GLSLstd450 spec is very lax about input signs, so we need to do the
bitcasting dance to implement it correctly.

Just treat any undefined argument as 0. It is risky to use the undefined
variable as it might not lower to a true constant.
