Re: sparc: ld: --relax and -r may not be used together

[Nicola Pero]

I spent more time on this.  Can you please try the latest version from trunk.
The only reasonably robust solution I could find was to use "-r" with GCC and
"-Wl,-r" with clang.

Testing would be welcome; let me know if it does or doesn't work with your 
compiler/platform
combination (PS: if you can compile gnustep-base from a clean source checkout, 
it works).

I hope it finally just works.  That would be a relief :-)

Thanks

Hi,

indeed... it is very strange..

http://hackage.haskell.org/trac/ghc/ticket/3791

is detailed and it even worked. I have seen several similar posts...

however according to
http://gcc.gnu.org/onlinedocs/gcc-3.2.3/gcc/Option-Summary.html#Option%20Summary

neither in it or in the 4.4/4.5 series I can find this option. The 
closest is no-relax-immediate but not for sparc. What is this, black 
magic? The quest for the hidden undocumented GCC option?
