spirv-fuzz: Efficiency improvements to fuzzer pass ( #4188 )
...
FuzzerPassConstructComposites is adapted to use AvailableInstructions
to manage available instructions, and to use zero constants when
trying to construct a composite for which not all fields can otherwise
be constructed. The change uncovered some cases where we create
structs and arrays with struct fields or components that are
block-decorated; these possibilities have been eliminated.

spirv-fuzz: Avoid invalidating analyses when splitting blocks ( #4218 )
...
It is easy to avoid the need to invalidate the def-use analysis and
instruction to block mapping when splitting blocks, and profiling has
revealed that invalidation of def-use in particular is expensive when
splitting many blocks. This change avoids these invalidations.

spirv-fuzz: Do not add too many dead blocks ( #4217 )
...
Profiling has shown that adding large numbers of dead block
transformations can be expensive because each on requires dominator
analysis information, and each one invalidates this information. There
is currently no obvious mechanism for incrementally updating the
dominator analysis. This change restricts the number of these
transformations that a single fuzzer pass will apply, to restrict this
performance bottleneck.

spirv-fuzz: Remove AddType methods from fuzzerutil ( #4204 )
...
Types should only be added to the module by spirv-fuzz via
transformations, so this change removes the AddType methods from
fuzzerutil, which were only called once each from the appropriate
transformation.
The transformations have been adapted so that they avoid redundantly
invalidating all analyses - they now update the def-use manager and
invalidate only the type manager.

spirv-fuzz: Avoid invalidating analyses ( #4176 )
...
The performance of spirv-fuzz is sometimes poor due to analyses being
conservatively invalidated. This can lead to quadratic time algorithms
when a fuzzer pass applies O(N) transformations, and where every
transformation e.g. depends on def-use analysis and invalidates
def-use analysis (because building def-use analysis is O(N)).
This change avoids invalidating analyses for certain transformations.

Use standard function to get stdin to binary mode. ( #4141 )
...
* Use standard function to get stdin to binary mode.
The fisrt implementation to try to change stdin to binary mode is not
protable. Using freopen has a lot of implementation defined behaviour,
and the code relied on that working.
Looking into the MSVC documentation, I do not see a protable way of
doing this. I've implemented a Windows specific method and do nothing
for other systems. In general, UNIX based systems do make a distinction
between text and binary files, so nothing needs to be done for them.
Fixes #2518
* Split ReadFile into two different functions.
We want to remove the flag parameter. So the original function has been
replaced with ReadBinaryFile and ReadTextFile. This should make the
code more readable.
* Change name of CorrectlyReadFile to avoid confusion.

their known-good glslang and its known-good spirv-tools and spirv-headers.
