mangler makes global symbol disappear on linux-ppc

[arekm@…]

Enviroment: linux-ppc, very fresh software, upcoming gcc 4.2, ghc 6.6. I was trying to build alex software which ended with:

GNU ld version 2.17.50.0.12 20070128
  Supported emulations:
   elf32ppclinux
   elf32ppc
   elf32ppcsim
ghc3729_0.hc:(.text+0x104a): undefined reference to `ParseMonad_alexStartPos_closure'
ghc3729_0.hc:(.text+0x104e): undefined reference to `ParseMonad_alexStartPos_closure'
dist/build/alex/alex-tmp/Info.o: In function `shII_info':
ghc3729_0.hc:(.text+0x106e): undefined reference to `Util_lvl1_closure'
ghc3729_0.hc:(.text+0x1072): undefined reference to `Util_lvl1_closure'
ghc3729_0.hc:(.text+0x107a): undefined reference to `Util_lvl1_closure'
dist/build/alex/alex-tmp/Info.o:(.rodata+0x40): undefined reference to `Util_lvl1_closure'

The problem is that these symbol disappear after going through mangler (so problem is visible only when -O2 is used)

In short the problem is that:

.globl ParseMonad_alexStartPos_closure

disappears.

I'm putting this in the 6.6.1 milestone for now as it looks pretty bad if it bites often, but I'm not sure if anyone's actively working on the registerised Linux/PPC port, so we might well end up punting on it.

No-one seems to be working on maintaining the registerised Linux/PPC port at the moment, so milestoning this as _|_.

Has anyone taken up the reg'd Linux/PPC port? If not, close as won't fix.

The mangler is dead.
