[ ghc-Bugs-642810 ] Still fails to build with GCC 3.2 on Mandrake

Summary: Still fails to build with GCC 3.2 on Mandrake

Initial Comment:

Following the instructions listed in other bug reports,
I bootstrapped GHC 5.04.1 on a machine with an older
GCC, then installed that on the target machine
(Mandrake 9.0, GCC 3.2).

But the mangler is still busted: compiling anything
with -O gives errors like:

| Prologue junk?: .globl __stginit_PrimPacked
| 	.type	__stginit_PrimPacked, <at> function
| __stginit_PrimPacked:
| 	pushl	%ebp
| 	movl	%esp, %ebp

Compiling with '-O -fasm' works, but GHC 5.04.1 still

RULES/SPECIALIZE not parsing:

Rules.hs:

module Rules where

my_id :: a -> a
my_id a = a

my_int_id :: Int -> Int
my_int_id a = a

{-# RULES my_id = my_int_id #-}
{-# SPECIALIZE my_id :: Int -> Int = my_int_id #-}

Neither of the pragmas are accepted.  The first elicits a parse error on
my_id, the second elicits a parse error on '='.

GHC 5.04.1 Solaris.

RE: RULES/SPECIALIZE not parsing:


> Rules.hs:
> 
> module Rules where
> 
> my_id :: a -> a
> my_id a = a
> 
> my_int_id :: Int -> Int
> my_int_id a = a
> 
> {-# RULES my_id = my_int_id #-}

Each rule should begin with a string, like:

  {-# RULES "my_id" my_id = my_int_id #-}

> {-# SPECIALIZE my_id :: Int -> Int = my_int_id #-}

These kind of specialise pragmas aren't supported any more, because the
same effect can be achieved using RULES (it looks like that's what you
were trying to do).

The docs have some bogusness, which I'll fix.

Cheers,

Initial Comment:
Trying to load into GHCi simple program (in attached 
file) I receive error stating I can declare class instances 
only for types defined using "data". I beleive it is a bug 
because Hugs handles this situation normally.

Bug in last CVS

I have a bug in a CVS version for MacOSX from tuesday:

While compiling last version of Frantk:

Compiling DisplaySimple    ( FranTkSrc/DisplaySimple.lhs,
FranTkSrc/DisplaySimple.o )
ghc-5.05: panic! (the `impossible' happened, GHC version 5.05):
        rename/RnExpr.lhs:164: Non-exhaustive patterns in function rnExpr

Please report it as a compiler bug to glasgow-haskell-bugs <at> haskell.org,
or http://sourceforge.net/projects/ghc/.

Best regards,
Nicolas Oury
