Remove support for ad hoc Slang IR compression (#6834)

2025-04-16T19:28:39+00:00

* Remove support for ad hoc Slang IR compression This change is part of a larger effort to clean up the approach to serialization in the Slang compiler. The overall goal is to simplify and streamline all of the serialization-related logic, so that we are left with code that is less "clever," and easier to understand for contributors to the codebase. Removing support for compression of serialized Slang IR has benefits that include: * Reduction in code complexity: consider things like the subtle way that the `FOURCC`s for compressed chunks were being computed from the uncompressed versions, and the mental overhead that goes into understanding that, for anybody who would dare to touch this code. * Reduction in testing burden: there have been, de facto, two very different code paths for serialization of the Slang IR, and it is not clear that the existing test corpus for Slang has sufficient coverage for both options. By having only a single code path, every test that performs any amount of IR serialization helps with test coverage of that one path. * Opportunity to explore alternatives. This is perhaps a reiteration of the first point, but once the code is stripped down to the simplest thing that could possibly work (I am not claiming it has reached that point yet), it becomes easier for contributors to understand, and it becomes more tractable for somebody to come along with an improved approach that performs better (in either compression ratio or performance) while still being maintainable. In my own local setup, I found that removing support for Slang IR compression led to the `slang-core-module-generated.h` file increasing in size from 46.1MB to 47.4MB. This increase in the `.h` file size for the core library binary only resulted in a release build of `slang.dll` increasing from 20.0MB to 20.2MB. Removing the ad hoc compression support has almost no impact on the size of actual binary Slang modules *so long* as the additional LZ4 compression step is being applied to them. * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

Use ankerl/unordered_dense as a hashmap implementation (#3036)

2023-08-16T00:57:47+00:00

* Correct namespace for getClockFrequency * missing const * Add missing assignment operator * Remove unused variables * Return correct modified variable * Use stable hash code for file system identity * terse static_assert * Structured binding for map iteration * Make (==) and getHashCode const on many structs * Add ConstIterator for LinkedList * Replace uses of ItemProxy::getValue with Dictionary::at * Extract list of loads from gradientsMap before updating it * Const correctness in type layout * Add unordered_dense hashmap submodule * Use wyhash or getHashCode in slang-hash.h * refactor slang-hash.h * Use ankerl/unordered_dense as a hashmap implementation Notable changes: - The subscript operator returns a reference directly to the value, rather than a lazy ItemProxy (pair of dict pointer and key) slang-profile time (95% over 10 runs): - Before: 6.3913906 (±0.0746) - After: 5.9276123 (±0.0964) * 64 bit hash for strings So they have the same hash as char buffers with the same contents * Narrowing warnings for gcc to match msvc * revert back to c++17 * Correct c++ version for msvc * Use path to unordered_dense which keeps tests happy * Do not assign to and read from map in same expression * Remove redundant map operations in primal-hoist * Split out stable hash functions into slang-stable-hash.h * 64 bit hash by default * regenerate vs projects * Correct return type from HashSetBase::getCount() * correct width for call to Dictionary::reserve * Use stable hash for obfuscated module ids * Signed int for reserve * clearer variable naming * Parameterize Dictionary on hash and equality functors * Allow heterogenous lookup for Dictionary * missing const * Use set over operator[] in some places * Remove unused function * s/at/getValue

Dictionary using lowerCamel (#2835)

2023-04-25T14:43:29+00:00

* #include an absolute path didn't work - because paths were taken to always be relative. * WIP lowerCamel Dictionary. * WIP more lowerCamel fixes for Dictionary. * Add/Remove/Clear * GetValue/Contains * Fix tabs in dictionary. Count -> getCount * Fix fields with caps. * Key -> key Value -> value Use m_ for members where appropriate. Use lowerCamel in linked list. * Some small fixes/improvements to Dictionary. * Kick CI.

Generalizing Serialization (#1563)

2020-09-30T17:28:56+00:00

* First pass at generalizing serializer. * Split out ReflectClassInfo * Use the general ReflectClassInfo * Fix some typos in debug generalized serialization. * Add calculation of classIds. Make distinct addCopy/add on SerialClasses. * Write up of more generalized serialization * WIP to transition from ASTSerialReader/Writer etc to generalized SerialReader/Writer and associated types. * Improvements to SerialExtraObjects. Keep RefObjects in scope in factory * Compiles with Serial refactor - doesn't quite work yet. * First pass serialization appears to work with refector. * Split out type info for general slang types. * Split out slang-serialize-misc-type-info.h * DebugSerialData -> SerialSourecLocData DebugSerialReader -> SerialSourceLocReader DebugSerialWriter -> SerialSourceLocWriter * Remove unused template that only compiles on VS. * Fix warning around unused function on non-VS.
