Implement DWARF debugging on powerpc64
debug:
ghc-stage2: panic! (the 'impossible' happened)
(GHC version 7.11.20151219 for powerpc64-unknown-linux):
dwarfReturnRegNo: Unsupported platform!
CallStack (from ImplicitParams):
error, called at compiler/nativeGen/Dwarf/Constants.hs:224:19 in ghc:Dwarf.Constants
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
Provide DWARF constants for registers.
Still TODO:
-
add unwinding information to StgCRun
to ensure that the unwinder can unwind from Haskell into C -
to support the RTS unwinder: add support to the initial register callback set_initial_registers
inrts/Libdw.c
-
Valid unwind records in stg_stop_thread
(defined inrts/StgStartup.cmm
) -
Support in the native code generator (by implementing the extractUnwindPoints
field ofNcgImpl
) -
Unwinding support in libdw
