Adding validation that the addressing declared by OpMemoryModel is
Logical and the memory model declared is VulkanKHR. Updating a bunch
of tests that were broken by this.
Fixes#2060
This commit will change the message for unknown extensions from an error
to a warning.
Code was added to limit the number of warning messages so that consummer
of the messages are not overwhelmed. This is standard practice in
compilers.
Many other issues were found at while looking into this. They have been
documented in #1950.
Fixes http://crbug.com/875547.
We currently register decorations in the first pass through the
instructions. This is a problem because the validator has not even
checked if the decoration instructions are valid yet. This can lead to
unexpected behaviour from these side table. For example, in
https://github.com/KhronosGroup/SPIRV-Tools/issues/1882, we use 5GB of
data to store 1 decoration for ids that are not even defined.
Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/1882.
This CL moves the various validate files into the val/ directory with
the rest of the validation infrastructure. This matches how opt/ is
setup with the passes with the infrastructure.
