Misc. bugs in HsParser

[Anders Lau Olsen]

HsParser does not allow method declarations to follow a default
implementation of a method.

class G a where
f :: a - a
f x = x
g :: a - a

Optional semicolons or empty statements are not permitted in
do-expressions.

f x = do ;; x ;

That is probably the reason why this example fails to parse too:

f x = do
y
where y = x

Happy generates uncompilable files

[Josef Svenningsson]

Hi!

Here's a small patch to fptool/mk/config.mk.in which I need for the
compiler to compile smoothely on my sparc:

*** config.mk.inThu Nov  8 17:12:46 2001
--- ../../fptools/mk/config.mk.in   Wed Nov  7 16:23:03 2001
***
*** 833,843 
  #
  # Options to pass to Happy when we're going to compile the output with
GHC
  #
- ifeq $(i386_TARGET_ARCH) 1
  GHC_HAPPY_OPTS= $(shell if ( test `echo $(HAPPY_VERSION)
| sed -e s/\(.*\)\..*/\1/g` -gt 1 || test `echo $(HAPPY_VERSION) |
sed -e s/.*\.\(.*\)/\1/g` -ge 9 ); then echo -agc; else echo -g; fi)
- else
- GHC_HAPPY_OPTS= -gc
- endif

  #
  # Stuff from fptools/literate
--- 833,839 


Why? Because with the -a flag happy generates files which uses the
Int16Rep function. This is only implemented for x86. :-(

Could you please add this patch? It would make my life a lot easier.

Cheers,

/Josef

(not too important) compiler bug

[Sacha Berger]

Hi!

I really like your work and personally I do not have to complain,
but ghc urges me to report it as a compiler bug:

ghc-c -o LinkBase.o LinkBase.hs

 panic! (the `impossible' happened):
Oversize heap check detected.  Please try compiling with -O.

Please report it as a compiler bug to [EMAIL PROTECTED]

LinkBase.hs contains (automatically generated) biiig lists, and using
the -O flag solves the problem (especially therefore I have no complain ;-)
