Add spirv-fuzz tool. (#2631)
The current tool can parse basic command-line argument, but generates
a binary identical to the input binary, since no transformations are
yet implemented.

42abaa099a Remove MarkV and Stats code. (#2576)
* Remove MarkV and Stats code.

This Cl removes the MarkV and Stats code from SPIRV-Tools. This code was
unused and currently un-maintained.

e3c64a374b Do not build spirv-reduce on iOS/tvOS/watchOS - it requires std::system which is not available on those platforms (#2355) 2019-02-04 09:39:39 -08:00

Move spirv_stats into tools/stats. (#1826)
The spirv_stats code is only used by the tools/stats module. This CL
moves the code to that module.

Validate the input to Optimizer::Run (#1799)
* Run the validator in the optimization fuzzers.

The optimizers assumes that the input to the optimizer is valid.  Since
the fuzzers do not check that the input is valid before passing the
spir-v to the optimizer, we are getting a few errors.

The solution is to run the validator in the optimizer to validate the
input.

For the legalization passes, we need to add an extra option to the
validator to accept certain types of variable pointers, even if the
capability is not given.  At the same time, we changed the option
"--legalize-hlsl" to relax the validator in the same way instead of
turning it off.

250a235a8d Add new compression algorithm and models
Add new "short descriptor" algorithm to MARK-V codec.

Add three shader compression models:
lite - fast, poor compression
mid - balanced
max - best compression

cfd95f3d5a Refactored compression debugger
Markv codec now receives two optional callbacks:
LogConsumer for internal codec logging
DebugConsumer for testing if encoding->decoding produces the original
results.

2401fc0a72 Refactored MARK-V API
- switched from C to C++
- moved MARK-V model creation from backend to frontend
- The same MARK-V model object can be used to encode/decode multiple
files
- Added MARK-V model factory (currently only one option)
- Added --validate option to spirv-markv (run validation while
encoding/decoding)

86627f7b3f Implement Linker (module combiner)
Add extra iterators for ir::Module's sections
Add extra getters to ir::Function
Add a const version of BasicBlock::GetLabelInst()

Use the max of all inputs' version as version

Split debug in debug1 and debug2
- Debug1 instructions have to be placed before debug2 instructions.

Error out if different addressing or memory models are found

Exit early if no binaries were given

Error out if entry points are redeclared

Implement copy ctors for Function and BasicBlock
- Visual Studio ends up generating copy constructors that call deleted
  functions while compiling the linker code, while GCC and clang do not.
  So explicitly write those functions to avoid Visual Studio messing up.

Move removing duplicate capabilities to its own pass

Add functions running on all IDs present in an instruction

Remove duplicate SpvOpExtInstImport

Give default options value for link functions

Remove linkage capability if not making a library

Check types before allowing to link

Detect if two types/variables/functions have different decorations

Remove decorations of imported variables/functions and their types

Add a DecorationManager

Add a method for removing all decorations of id

Add methods for removing operands from instructions

Error out if one of the modules has a non-zero schema

Update README.md to talk about the linker

Do not freak out if an imported built-in variable has no export

c25b5bea35 Add SPIRV_SPIRV_COMPRESSION option to cmake
The option is off by default.
cmake -DSPIRV_BUILD_COMPRESSION=ON ..
enables the compression lib, executable, and test build.

fd70a1d7a0 Define variable to skip installation
If this is used as a static library in another project, this does not
need to be installed, and otherwise will just clutter the application's install.
To use, define SKIP_SPIRV_TOOLS_INSTALL which internally defines
ENABLE_SPIRV_TOOLS_INSTALL to control installation.

Also include GNUInstallDirs to get standard output 'lib' directory which is sometimes 'lib64' and not 'lib'

73e8dac5b9 Added compression tool tools/spirv-markv. Work in progress.
Command line application is located at tools/spirv-markv
API at include/spirv-tools/markv.h

At the moment only very basic compression is implemented, mostly varint.
Scope of supported SPIR-V opcodes is also limited.

Using a simple move-to-front implementation instead of encoding mapped
ids.

Work in progress:
- Does not cover all of SPIR-V
- Does not promise compatibility of compression/decompression across
  different versions of the code.

4f216402ba Added statistical analysis tool (tool/stats)
Currently analyzes percentages of the following:
- version (how many 1.0 or 1.1)
- generator
- extension
- capability
- opcode prevalence

c804c125c5 Autogenererating enum-string mappings from grammar
Autogenerating the following code:
- extension enum
- extension-to-string
- string-to-extension
- capability-to-string

Capability mapping table will not compile if incomplete.
TODO: Use "spirv-latest-version.h" instead of 1.1.

Added function to generate capability tables for tests.

996a814ae3 Add spirv-cfg to dump a GraphViz graph of the CFG
This is experimental, and has not tests.
It's been used to debug validation of structured control flow.

- Has a legend describing special arcs to merge blocks and continue
  targets.
- Labels the function entry block, with the Id of the function.

9166854ac9 Add CHANGES file with high level software history
Add a high level version number for SPIRV-Tools, beginning
with v2016.0-dev.  The README describes the format of the
version number.

The high level version number is extracted from the CHANGES
file.  That works around:
 - stale-bait for when we don't add tags to the repository
 - our inability to add tags to the repository

Option --version causes spirv-as, spirv-dis, and spirv-val to
show the high level version number.

Add spvSoftwareVersionString to return the C-string for
the high level version number.

Add spvSoftwareVersionDetailsString() so that clients can get
more information if they want to.
Also allows us to clean up the uses in the tool executables files,
so now only one file includes build-version.inc.

Move the update-build-version logic to the only
CMakeLists file that needs it.

The update build version script takes a new argument
to name the output file.
