Hi all!
I gave a shot at compiling core llvm with a Solaris 9 machine.
The compiler is FSF gcc 3.4.6. I am building trunk in the release version.
So far I did not run tests (no dejagnu installed).
Here are my findings:
0) Configuring. I had to suppress the solaris tools by:
env AR=/opt/gnu/bin/ar NM=/opt/gnu/bin/nm RANLIB=/opt/gnu/bin/ranlib
STRIP=/opt/gnu/bin/strip ../llvm/configure --enable-optimized
00) I had to include the libtool-related .so libraries by
setting LD_LIBRARY_PATH appropriately
1) setrlimit issue:
RLIMIT_RSS is not defined. This seems to be conditionalized for cygwin,
a better test appears to be an "#ifdef RLIMIT_RSS"
See patches below.
2) round() not defined:
http://forum.java.sun.com/thread.jspa?messageID=9567848&tstart=0#9567848
seems to describe this problem.
The solution is simple. (use floor(x + 0.5))
Patch below. This solves the MS compiler issue too (same thing).
Other possibility is to use configure to determine the presence of round().

Should we #define powf as pow?
Better possibly is to differentiate by a configure test.
I can come up with a patch.

Y) Good news: gmake -j 10 seems to work flawlessly :-)
Z) I volunteer to fill in PRs if these problems persist for the next days.
