Simon Jakobi pushed to branch wip/sjakobi/T26964 at Glasgow Haskell Compiler / GHC Commits: 1306ca61 by Simon Jakobi at 2026-06-10T12:32:33+02:00 Address review feedback on -fcheck-prim-bounds error messages Review feedback from Andreas Klebinger on !16130: - Pass the primop name explicitly from emitPrimOp through the StgToCmm helpers to the bounds-check emitters, instead of stashing it in FCodeState. Removes fcs_prim_op, withCurrentPrimOpName and getCurrentPrimOpName; emitPrimOp binds op_name once and the do*/emit* helpers thread it down to emitBoundsCheck, emitRangeBoundsCheck and emitCheckedMemcpyCall. - Make the argument order of rtsOutOfBoundsAccess match ASSERT_IN_BOUNDS(op, ind, sz): the primop name now comes first, the module name stays last. - Move the module-name literal helper next to getModuleName in GHC.StgToCmm.Monad, renamed to getModuleNameCLit.
