Import ghc-7.6.3 as lang/ghc7.
Based on wip/ghc, mostly worked by phonohawk, with patches from jperkin@.
And some modifications and buit of Bootstrap binaries for 7.6.3 by me.
GHC: The Glasgow Haskell Compiler.
The Glasgow Haskell Compiler is a robust, fully-featured, optimising
compiler for the functional programming language Haskell 98
(http://www.haskell.org). GHC compiles Haskell to either native code
or C. It implements numerous experimental language extensions to
Haskell, including concurrency, a foreign language interface, several
type-system extensions, exceptions, and so on. GHC comes with a
generational garbage collector, a space and time profiler, and a
comprehensive set of libraries.

We have to make the visiblity of StgRun and StgReturn to "hidden" not
|
|
|
|
|
to trigger a bug in old binutils which results in:
|
|
|
|
|
|
|
|
|
|
ld: rts/dist/build/RtsStartup.dyn_o: relocation R_X86_64_PC32
|
|
|
|
|
against `StgRun' can not be used when making a shared object;
|
|
|
|
|
recompile with -fPIC
|
|
|
|
|
|
|
|
|
|
With this workaround we can no longer override those two symbols using
|
|
|
|
|
LD_PRELOAD, but I think there is no reason to do so anyway.

This has already been fixed in the upstream:
