Add relax_nan_checks options.
|
|
Makes codegen from typical D3D emulation SPIR-V more readable.
Also makes cross compilation with NotEqual more sensible.
It's very rare to actually need the strict NaN-checks in practice.
Also, glslang now emits UnordNotEqual by default it seems, so give up
trying to assume OrdNotEqual. Harmonize for UnordNotEqual as the sane
default.

Fixes numerous CTS tests of types
dEQP-VK.pipeline.interface_matching.vector_length.member_of_*,
passing complex nested structs between stages as stage I/O.
- Make add_composite_member_variable_to_interface_block() recursive to allow
struct members to contain nested structs, building up member names and access
chains recursively, and only add the resulting flattened leaf members to the
synthetic input and output interface blocks.
- Recursively generate individual location numbers for the flattened members
of the input/output block.
- Replace to_qualified_member_name() with append_member_name().
- Update add_variable_to_interface_block() to support arrays as struct members,
adding a member to input and output interface blocks for each element of the array.
- Pass name qualifiers to add_plain_member_variable_to_interface_block() to allow
struct members to be arrays of structs, building up member names and access chains,
and adding multiple distinct flattened leaf members to the synthetic input and
output interface blocks.
- Generate individual location numbers for the individual array members
of the input/output block.
- SPIRVCrossDecorationInterfaceMemberIndex references the index of a member
of a variable that is a struct type. The value is relative to the variable,
and for structs nested within that top-level struct, the index value needs
to take into consideration the members within those nested structs.
- Pass var_mbr_idx to add_plain_member_variable_to_interface_block() and
add_composite_member_variable_to_interface_block(), start at zero for each
variable, and increment for each member or nested member within that variable.
- Add unit test shaders-msl/vert/out-block-with-nested-struct-array.vert
- Add unit test shaders-msl/vert/out-block-with-struct-array.vert
- Add unit test shaders-msl/tese/in-block-with-nested-struct.tese

Clang added -Wunqualified-std-cast-call in
https://reviews.llvm.org/D119670, which warns on unqualified std::move
and std::forward calls. This change qualifies these calls to allow the
project to build on HEAD Clang -Werror.

Various fixes
|
|
|
|
The patterns where we force temporary due to invalid/overused expression -> recompile
should be seen as making forward progress, and there are very rare scenarios where
these recompiles can cascade into many loops.
Refactor this style of logic into a new function which is equivalent to handle_invalid_expression().
|
|
Should be seen as a hack, but it's pragmatic in some scenarios.
|
|
Missed some cases where we did not handle the loaded type width
properly.
|
|
This can happen for access chains into buffer objects which were marked
as potentially hoisted, but it's benign in almost all cases.
|
|
|
|
Update documentation for descriptor set support in MSL/HLSL.
|
|
Ancient outdated README.
|
|
When emitting a normalize OP, conditionally stop using the fast namespace
|
|
MSL: Rethink how opaque descriptors are passed to leaf functions.
|
|
Handle aliased names in spec constants.
|
|
We were passing arrays by value which the compiler fails to optimize,
causing abyssal performance. To fix this, we need to consider that
descriptors can be in constant or const device address spaces.
Also, lone descriptors are passed by value, so we explicitly remove address
space qualifiers.
One failure case is when shader passes a texture/sampler array as an
argument. It's all UniformConstant in SPIR-V, but in MSL it might be
thread, const device or constant, so that won't work ...
Global variable use works fine though, and that should cover 99.9999999%
of use cases.

Need to register resource name.
|
|
MSL: Handle constant construct of block-like array types.
|
|
Need this to be context sensitive, since array of block-like struct is
template, but struct of block-like array is C-style.
Also, test a mix and match, so we have constant array of block-like
struct with array inside. :v
|
|
MSL: Handle signed atomic min/max.
|
|
C++ deduces this based on the pointer type, so cast to atomic_uint/int
if we have to.
|
|
Rework how loop iteration counts are validated.
|
|
Do not forward expressions which carry a huge amount of dependencies.
|
|
Introduces an idea of a recompilation making forward progress.
There are some extreme edge cases where we need more than 3 loops, but
only allow this in specific circumstances where we can reason about
forward progress being made.
|
|
Need to force temporaries eventually, or compilers have a tendency to
explode.
