Marge Bot pushed to branch master at Glasgow Haskell Compiler / GHC Commits: 2a218737 by ARATA Mizuki at 2026-03-23T11:11:39-04:00 Add 128-bit SIMD support to AArch64 NCG Changes: - Add `Format` field to vector-capable instructions. These instructions will emit `vN.4s` (for example) as a operand. - Additional constructors for `Operand`: `OpVecLane` represents a vector lane and will be emitted as `vN.<width>[<index>]` (`vN.s[3]` for example). `OpScalarAsVec` represents a scalar, but printed as a vector lane like `vN.<width>[0]` (`vN.s[0]` for example). - Integer quot/rem are implemented in C, like x86.

Similarly, a class of vectors with same values can be encoded using FMOV, MOVI, or MVNI. - - - - - 24 changed files: - compiler/CodeGen.Platform.h - compiler/GHC/CmmToAsm/AArch64/CodeGen.hs - compiler/GHC/CmmToAsm/AArch64/Instr.hs - compiler/GHC/CmmToAsm/AArch64/Ppr.hs - compiler/GHC/CmmToAsm/AArch64/Regs.hs - compiler/GHC/CmmToAsm/Reg/Graph/TrivColorable.hs - compiler/GHC/Driver/Config/StgToCmm.hs - docs/users_guide/9.16.1-notes.rst - rts/include/stg/Prim.h - rts/prim/vectorQuotRem.c - + testsuite/tests/simd/should_run/FloatConstant.hs - + testsuite/tests/simd/should_run/FloatConstant.stdout - + testsuite/tests/simd/should_run/IntConstant.hs - + testsuite/tests/simd/should_run/IntConstant.stdout - testsuite/tests/simd/should_run/all.T - testsuite/tests/simd/should_run/int16x8_shuffle.hs - testsuite/tests/simd/should_run/int16x8_shuffle.stdout - testsuite/tests/simd/should_run/int16x8_shuffle_baseline.hs - testsuite/tests/simd/should_run/int16x8_shuffle_baseline.stdout - testsuite/tests/simd/should_run/int8x16_shuffle.hs - testsuite/tests/simd/should_run/int8x16_shuffle.stdout - testsuite/tests/simd/should_run/int8x16_shuffle_baseline.hs - testsuite/tests/simd/should_run/int8x16_shuffle_baseline.stdout - testsuite/tests/simd/should_run/simd013C.c The diff was not included because it is too large.
