This PR add supports to use specialize constant in generic parameter, and that parameter can also be used as array size, e.g. following code should work: ``` struct MyStruct<let N: int> { float buffer[N]; } MyStruct<SpecConstVar> s; ``` - Loose the restriction from Link-Time to SpecializationConstant when extract generic argument - Tweak the logic of how we decide whether a inst is hoistable. Besides checking existing hoistable flag of each IRInst, when we detect a IRInst's type is SpecConstRateType, we will treat that inst hoistable. Because IRInst in global scope can be deduplicated, and every SpecConstRateType inst should be in the global scope or IRGeneric scope (which will be at global scope after specialization). - Remove the SpecConstIntVal to IRInst map in IR lowering logic, because we already have way to deduplicate the global scope IR. 2025-04-03T04:17:15+00:00 Ronan ro.cailleau@gmail.com 2025-04-03T04:17:15+00:00 urn:sha1:6b44630afe4ff180ba608142e9515abcd369775e * Fixed generic interface specialization crashes: - Add an export decoration to specialized generic interfaces. * Fixed generic interface specialization crashes: - Add an export decoration to specialized generic interfaces. - Use getTypeNameHint(...) instead of a manual mangler. * In cloneInstDecorationsAndChildren: specialize all linkage decorations, not just the exports. - If a linkage decoration is already present, it is not specialized and replaced by the specialized one. - If a specialization uses the TypeNameHint, sanitize it to be used as an identifier. - Use the identifier name sanitizer from slang-mangle. * Added tests/generics/generic-interface-linkage.slang - See #6601 and #6688 2025-01-17T16:58:18+00:00 Julius Ikkala julius.ikkala@gmail.com 2025-01-17T16:58:18+00:00 urn:sha1:ddc4a1799a9d21084604cc2bf334d5d91cb329e3 * Fix nullptr in generic specialization * Fix formatting * Revert "Fix nullptr in generic specialization" and add emitPtrLit instead * Add type parameter to getPtrValue() --------- Co-authored-by: Yong He <yonghe@outlook.com> 2024-10-29T06:49:26+00:00 Ellie Hermaszewska ellieh@nvidia.com 2024-10-29T06:49:26+00:00 urn:sha1:f65d756bff8d4c5cbc15bd0322a2ae8e6b896a21 * format * Minor test fixes * enable checking cpp format in ci 2024-09-19T03:42:07+00:00 venkataram-nv vedavamadath@nvidia.com 2024-09-19T03:42:07+00:00 urn:sha1:b808aa4df50d46eaa569561f7e464c55c1c2d72a * Transferring source locations when creating phi instructions * Tracking for simple variables * Deriving source locations for loop counters * Printing checkpoint structure breakdown * More readable output format * Special behavior for loop counters * Writing report to file * Add slangc option to enable checkpoint reports * Display types of checkpointed fields * Message in case there are no checkpointing contexts * Catch source locations for function calls * Source cleanup * Fix compilation warnings * Remove stray dump() * Provide the report through diagnostic notes * Add missing path for sourceLoc during unzip pass * Add tests for reporting intermediates * Include more transfer cases for source locations * Fix ordering in address elimination * Fill in more holes with source location transfer * Remove debugging line * Reverting changes to diagnostic sink * Simplify address elimination using source location RAII contexts * Eliminating manual source loc transfers in forward transcription * Fix local var adaptation to use RAII location setter * Simplify primal hoisting logic for source location transfer * Simplify unzipping with RAII location scopes * Simplify transpose logic * Cleaning up for rev.cpp * Reverting spacing changes * Fix mistake with source loc RAII instantiation * Fix formatting issues 2024-08-21T03:51:57+00:00 Yong He yonghe@outlook.com 2024-08-21T03:51:57+00:00 urn:sha1:f9f6a28df40f418ddd0c8ff3b9cacccdb085e202 * Support dependent generic constraints. * Fix warning. * Update comment. * Fix. * Add a test case to verify fix of #3804. * Address review. 2023-08-17T18:45:13+00:00 Sai Praveen Bangaru 31557731+saipraveenb25@users.noreply.github.com 2023-08-17T18:45:13+00:00 urn:sha1:945409c4c6871c18aad24086c594cc66b5913733 * Merge * WIP: Complete auto-diff logic for existential types * Revert "Add compiler option for generating representative hash" This reverts commit 13b09ef4621e73844c96d64d9c111a8ed0d45aae. * More fixes for fwd-mode AD on existential types * Add anyValueSize inference pass * Fix checking of `Differential.Differential==Differential` * In-progress: infer any-value-size for existential types * Existentials now work in forward-mode * Overhaul handling of existential AD types.
