Favour 'integrity' over 'coherence' as a replacement for 'sanity'. (#3619) 2020-09-10 09:52:21 -04:00

Avoid use of 'sanity' and 'sanity check' in the code base (#3585)
In line with:

  https://source.android.com/setup/contribute/respectful-code

this change uses the terms 'coherence' and 'coherence check' where
'sanity' and 'sanity check' were previously used.

af7410597e graphics robust access: use signed clamp (#3073)
Access chain indices are always interpreted as signed integers.
So use signed clamp instead of unsigned clamp.  We must also
clamp to the max signed int for the index type.

Fixes #3072

Fix some clang-tidy issues in graphics_robust_access_pass (#2998)
One remains: the fact that the image-texel-pointer modification
is mostly dead code. But that's intentional for now.

5a48c0da15 SPIRV-Tools support for SPIR-V 1.5 (#2865)
* Ensure same enum values have consistent extension lists

* val: fix checking of capabilities

The operand for an OpCapability should only be
checked for the extension or core version.
The InstructionPass registers a capability, and all its implied
sub-capabilities before actually checking the operand to an
OpCapability.

* Add basic support for SPIR-V 1.5

- Adds SPV_ENV_UNIVERSAL_1_5
- Command line tools default to spv1.5 environment
- SPIR-V 1.5 incorporates several extensions.  Now the disassembler
  prefers outputing the non-EXT or non-KHR names.  This requires
  updates to many tests, to make strings match again.
- Command line tests: Expect SPIR-V 1.5 by default

* Test validation of SPIR-V 1.5 incorporated extensions

Starting with 1.5, incorporated features no longer require
the associated OpExtension instruction.

Add pass to inject code for robust-buffer-access semantics (#2771)
spirv-opt: Add --graphics-robust-access

Clamps access chain indices so they are always
in bounds.

Assumes:
- Logical addressing mode
- No runtime-array-descriptor-indexing
- No variable pointers

Adds stub code for clamping coordinate and samples
for OpImageTexelPointer.

Adds SinglePassRunAndFail optimizer test fixture.

Android.mk: add source/opt/graphics_robust_access_pass.cpp

Adds Constant::GetSignExtendedValue, Constant::GetZeroExtendedValue
