Hello everybody, I've got some trouble compiling haskell-code on a sparc system. As soon as I use the option '-O', ghc starts spilling messages like these: --- snip --- [...] /u/joe/built/lib/ghc-5.00.2/includes/Regs.h:255: warning: call-clobbered register used for global register variable [...] /tmp/ghc15733.hc:5391: warning: deprecated initialization of zero-length array /tmp/ghc15733.hc:5391: warning: (near initialization for `Main_main_closure.payload') [...] --- snap --- The 2nd type occurs way more often, but it doesn't look really bad. What I'm more worried about is the first. To use an already used register? Perhaps anyone could explain these messages to me? It seems, however, that the code produced is okay. Things get worse, if I try to use gcc for code-generation. The messages *seem* to remain the same. Invocation of ghc is basically the same as above, w/ '-fvia-C -O2-for-C' added: --- snip --- mai00dqr@userv1:~/Diplom/cls/src> make /u/joe/built/bin/ghc-5.00.2 -O -fvia-C -O2-for-C -cpp -DBEGIN_GHC_ONLY='-}' -DEND_GHC_ONLY='{-' -DBEGIN_HUGS_ONLY='{-' -DEND_HUGS_ONLY='-}' -package text -package util -i../lib/parsec-250101 -i/u/joe/built/lib/ghc-5.00.2/imports -lncurses --make Main -o cls ghc-5.00.2: chasing modules from: Main [...] --- snap --- The code generated now definitely is not okay: --- snip --- mai00dqr@userv1:~/Diplom/cls/src> ./cls Segmentation Fault --- snap --- Here's what I'm using: --- snip --- mai00dqr@userv1:~> gcc --version 3.0.2 mai00dqr@userv1:~> uname -a SunOS userv1 5.8 Generic_108528-12 sun4u sparc SUNW,Ultra-80 --- snap --- Is the segmentation fault perhaps related to an interoperability between ghc and the latest gcc-versions? On a Linux-machine using the same ghc-version but gcc-2.96 '-O -fvia-C -O2-for-C' doesn't cause any problems (neither does it cause any messages like the above ones). If it is a problem related to the version of gcc, how do I tell ghc which version to use? I only know how to do that on the commandline. Any hints would be greatly appreciated.
