Summary: ghc fails with -O flags on Mandrake
Initial Comment:
Hi the Glorious GHC Team,
I suppose that it can be considered a bug that ghc fails to
compile with -On, n>0 option while it compiles fine with no
optimisation flags. For example, for a module as simple as:
module Test where
f x = x
compiler fails with:
[EMAIL PROTECTED] LHS]$ ghc -O -c Test.hs
Prologue junk?: .globl __stginit_Test
__stginit_Test:
pushl %ebp
movl %esp, %ebp
Compilation goes through when it is called with ghc -c Test.hs.
I installed ghc version 5.04.3 on my Mandrake 9.0 Linux from
a binary tar.bz file. The installation process went problemless;
below please find log files generated for ./configure and for
make install.
I wonder if the problem has anything to do with version
differences
between the libraries used to produce a binary distribution
and the ones that came with Mandrake 9.0. Of course, I've got
both libreadline.so.4 and libncurses.so.5, as specified
on ghc download page. Still, I wasn't able to install ghc from rpms
because of unsatisfied requirements. For example,
(.....
Andrew Moran's rpm complains:
[EMAIL PROTECTED] rysiek]# rpm --install ghc-5.04.3-1.i386.rpm
error: failed dependencies:
libc.so.6(GLIBC_2.3) is needed by ghc-5.04.3-1
libreadline.so.4 is needed by ghc-5.04.3-1
I understand the first of these complaints: /lib/libc.so.6 comes
from glibc-2.2.5-16mdk on Mandrake, so GLIBC versions differ.
Still, I don't know, how to read the second complain
[EMAIL PROTECTED] rysiek]# locate libreadline
/lib/libreadline.so.4
/lib/libreadline.so.4.1
/lib/libreadline.so.4.2
/lib/libreadline.so.4.3
This means that libreadline.so.4 is available, so perhaps the name
of
its rpm matters:
[EMAIL PROTECTED] rysiek]# rpm -q -f /lib/libreadline.so.4
readline-4.3-4mdk
.....)
Anyway, after installation from a binary distribution went
problemless I would expect compiler to work 99,99999%
problemless. In a situation when -On, n>0 options don't work
I am unable to install fptools from their original bunch, for
example. I am also not sure if it was possible to compile ghc
from its sources. (I didn't try it, I expect, however, that ghc
itself is best compiled with lots of optimisation flags.)
With Best Regards,
Rysiek

Hi,
Thanks for your help so far.
I've just noticed that this bug is in version 6.0 too.

This is a dup of bug #632021. The fix was made to the
HEAD, but for some reason wasn't merged into the branch.
I'll look into merging it.
The workaround is to add -optc -mno-omit-leaf-frame-pointer
to the command line.

Please do the following, using the Test.hs you mentioned in
the report:
$ ghc -keep-raw-s-file -c -O Test.hs
and attach the resulting file Test.raw_s.
