Alan Zimmerman pushed to branch wip/az/ghc-cpp at Glasgow Haskell Compiler / GHC Commits: 91564daf by Matthew Pickering at 2025-04-24T00:29:02-04:00 ghci: Use loadInterfaceForModule rather than loadSrcInterface in mkTopLevEnv loadSrcInterface takes a user given `ModuleName` and resolves it to the module which needs to be loaded (taking into account module renaming/visibility etc). loadInterfaceForModule takes a specific module and loads it. The modules in `ImpDeclSpec` have already been resolved to the actual module to get the information from during renaming. Therefore we just need to fetch the precise interface from disk (and not attempt to rename it again). Fixes #25951 - - - - - 2e0c07ab by Simon Peyton Jones at 2025-04-24T00:29:43-04:00 Test for #23298 - - - - - 0eef99b0 by Sven Tennie at 2025-04-24T07:34:36-04:00 RV64: Introduce J instruction (non-local jumps) and don't deallocate stack slots for J_TBL (#25738) J_TBL result in local jumps, there should not deallocate stack slots (see Note [extra spill slots].) J is for non-local jumps, these may need to deallocate stack slots. - - - - - 1bd3d13e by fendor at 2025-04-24T07:35:17-04:00 Add `UnitId` to `EvalBreakpoint` The `EvalBreakpoint` is used to communicate that a breakpoint was encountered during code evaluation. This `EvalBreakpoint` needs to be converted to an `InternalBreakpointId` which stores a `Module` to uniquely find the correct `Module` in the Home Package Table. The `EvalBreakpoint` used to store only a `ModuleName` which is then converted to a `Module` based on the currently active home unit. This is incorrect in the face of multiple home units, the break point could be in an entirely other home unit! To fix this, we additionally store the `UnitId` of the `Module` in `EvalBreakpoint` to later reconstruct the correct `Module` All of the changes are the consequence of extending `EvalBreakpoint` with the additional `ShortByteString` of the `UnitId`. For performance reasons, we store the `ShortByteString` backing the `UnitId` directly, avoiding marshalling overhead. - - - - - 0fc630f6 by Alan Zimmerman at 2025-04-24T18:16:55+01:00 GHC-CPP: first rough proof of concept Processes #define FOO #ifdef FOO x = 1 #endif Into [ITcppIgnored [L loc ITcppDefine] ,ITcppIgnored [L loc ITcppIfdef] ,ITvarid "x" ,ITequal ,ITinteger (IL {il_text = SourceText "1", il_neg = False, il_value = 1}) ,ITcppIgnored [L loc ITcppEndif] ,ITeof] In time, ITcppIgnored will be pushed into a comment - - - - - 7b9e88bc by Alan Zimmerman at 2025-04-24T18:16:55+01:00 Tidy up before re-visiting the continuation mechanic - - - - - 3122938c by Alan Zimmerman at 2025-04-24T18:16:55+01:00 Switch preprocessor to continuation passing style Proof of concept, needs tidying up - - - - - 681bef59 by Alan Zimmerman at 2025-04-24T18:16:55+01:00 Small cleanup - - - - - b440e634 by Alan Zimmerman at 2025-04-24T18:16:55+01:00 Get rid of some cruft - - - - - 2b346c2a by Alan Zimmerman at 2025-04-24T18:16:56+01:00 Starting to integrate.
