-Make more use of InstructionBuilder instruction helper methods
-Use MakeUnique<>() rather than new
-Add InstrumentPass::GenReadFunctionCall() which optimizes function
calls in a loop with constant arguments and no side effects.
This is a prepatory change for future work on the instrumentation
code which will add more generated functions.
Add a flags field at the first offset within this buffer.
Define flags to allow buffer OOB checking to be enabled or
disabled at run time. This is to support VK_EXT_pipeline_robustnes.
Add name annotations to the generated instrumentation code to
make it easier to understand. Example spirv-cross output:
vec4 _140;
if (0u < inst_bindless_direct_read_4(0u, 0u, 1u, uint(_19)))
{
_140 = texture(textures[nonuniformEXT(_19)], inUV);
}
else
{
inst_bindless_stream_write_4(50u, 1u, uint(_19), 0u);
_140 = vec4(0.0);
}
Using SinglePassRunAndMatch<> instead of SinglePassRunAndCheck<>
makes tests more concise and makes it possible to use pattern
matching features.
Using Effcee stateful pattern matching to make it less repetitive
to check for generated functions and global variables.
This approach isn't worth
it for DebugPrintf functions because the generated code will change
depending on how many parameters are passed to every debugPrintfEXT()
call.
Create a pass to instrument OpDebugPrintf instructions. This pass replaces all OpDebugPrintf instructions with instructions to write a record containing the string id and the all specified values into a special printf output buffer (if space allows). This pass is designed to support the printf validation in the Vulkan validation layers.
