Worked on the llvm/circt repository to develop and integrate an Inter-Module Dead Code Elimination (IMDCE) pass for the HW dialect, focusing on cross-module liveness analysis and aggressive dead code removal. The approach identified alive values by tracing connections to public ports or symbols and propagated liveness through module dataflow, enabling more efficient hardware generation and reduced intermediate representation size. Further enhancements included module rewriting APIs to optimize hardware area and latency, relocation of utility functions for improved code organization, and comprehensive test coverage. All work was implemented in C++ with a strong emphasis on compiler and hardware design principles.

Mar 1, 2026Delivered the initial Inter-Module Dead Code Elimination (IMDCE) pass for the HW dialect in CIRCT, enabling cross-module liveness analysis and aggressive dead-code pruning. The pass marks alive values based on connections to public ports or symbols and propagates liveness through module dataflow, laying groundwork for more efficient hardware generation and reduced IR size. Primary commit: 64f2d75f33470b59feb5a1ccfd094be232d7735c ("[HW] Add HW IMDCE pass (#9609)"). No major bugs fixed this month; focus was on feature delivery, robustness of the analysis, and code quality.
