[OSUNIX-dev] Open64 port HelloWorld works!

["C. Bergström"]

Just wanted to share a quick update with everyone..

With some help from Rayson we're down to the last parts

1) Fix segfault with ipa (I suspect FreeBSD/OpenSolaris)
2) Minor linker change (Sun ld only)
3) CPUID for platforms without /proc/cpuinfo (FreeBSD/OpenSolaris)
4) Makefile clean-up

Anyone who wants to help can email me and I'll set them up with ssh access.
-----------------

Here's the patch against current svn.
http://pkg.osunix.org/open64/open64-opensolaris-fbsd-merged-3-12.diff.gz

------------------

Currently adding -ipa will dump core

/usr/local/src/bar/open64/usr/lib/ipl -PHASE:p:i -O2 -show -TARG:abi=n32 
-LANG:cxx_openmp=on -LANG:=ansi_c -fB,hello.B -fo,hello.o hello.c -cmds 
opencc -show -TARG:abi=n32 -TARG:processor=anyx86 -TARG:sse2=off 
-TARG:mmx=off -TARG:sse=off -TARG:sse3=off -TARG:3dnow=off -TARG:sse4a=off

Linker should pass -R instead of -rpath-link

With that change the hello world will link and run..

Hope I haven't made too much noise..


Thanks
