LuisaGroup/LuisaCompute

ir-pipeline

Legacy IR and XIR compiler pipeline, AST lowering, SSA IR, and optimization passes.

xir-passes

XIR transformation pass authoring under src/xir/passes/.

xmake

XMake build configuration, options, commands, and patterns for LuisaCompute.

lc-optimize

Optimize LuisaCompute DSL kernels using warp/wave primitives, shared-memory aggregation, and block-level collectives. Use when kernels bottleneck on atomics, reductions, or inter-thread communication.

spirv-codegen

Native Vulkan XIR-to-SPIR-V codegen, legalization, validation, bindings, control flow, and target features.

glslang

glslang SPIR-V Builder API for types, instructions, control flow, and decorations.

git

Show uncommitted changes and commit history via git. Use when: (1) inspecting what changed in a file before committing, (2) checking diff of tracked/new/deleted files, (3) reviewing a specific commit's changes, (4) listing files changed in a commit.

test

Boost.UT test layout, device helpers, adding tests, and running them.

backend-architecture

Backend plugin architecture, DeviceInterface, dynamic loading, and command encoding.

cmake

CMake build options, custom functions, and backend patterns for LuisaCompute.

lc-runtime

Runtime API: Context, Device, Stream, buffers, images, ray tracing, and rasterization.

llvm-spirv

Experimental Vulkan AST-to-LLVM-to-SPIR-V backend, its fail-closed runtime-interface boundary, LLVM build integration, and validation path.

hlsl

HLSL code generation, StringBuilder patterns, builtin headers, and DXIL embedding.

lc-dsl

DSL kernels, callables, structs, buffers, atomics, control flow, and dispatch.

lc-ast

Locate AST read/write usage markers and builtin CallOp usage rules in LuisaCompute. Use when investigating or modifying AST variable usage propagation, FunctionBuilder internals, or CallOp argument marking.

debug

Debug crashes and test failures via stack-traces, host/device logging, and DSL buffer inspection.

ast

Manual AST construction with FunctionBuilder for kernels and callables without DSL sugar.

cpp-style

C++ naming, formatting, static analysis, and RTTI rules for LuisaCompute.

lsp

clangd LSP over HTTP for C++ syntax checks and symbol navigation in LuisaCompute sources.

project-structure

Project layout, module architecture, compiler pipeline, and design patterns.

rust-workspace

Rust IR, compiler transforms, CPU backend, FFI, and crate structure.

spv-opt

SPIRV-Tools optimizer pass development, IR manipulation, and PassTest registration.

yyjson

High-performance C JSON parsing, creation, and modification with yyjson.

lc-core

Core library: traits, types, logging, math, fiber, allocators, and STL containers.

lc-vstl

vstd containers: HashMap, queues, pools, variant, smart pointers, and utilities.
