URL: https://github.com/llvm/llvm-project/commit/036c6cb37c5647017f98291b3ecd6fb5a2ee2cf4 DIFF: https://github.com/llvm/llvm-project/commit/036c6cb37c5647017f98291b3ecd6fb5a2ee2cf4.diff LOG: [RISCV] Add Qualcomm uC Xqcibi (Branch Immediate) extension (#130779) This extension adds twelve conditional branch instructions that use an immediate operand for the source. The current spec can be found at: https://github.com/quic/riscv-unified-db/releases/tag/Xqci-0.7.0 This patch adds assembler only support.
