[LLVMdev] Building llvm 1.8a on apple x86

[Reid Spencer]

Hi Ryan,

I couldn't replicate this situation on Linux. To diagnose we're going to
need more information. If possible, could you get a back trace on the
seg fault? Here's how you can do that:

cd {objdir}/lib/VMCore/
rm Release/Intrinsics.gen.tmp
make VERBOSE=1

The verbose output from "make" will give you the command line that is
failing. Next you need to run tblgen under the debugger:

gdb {objdir}/Release/bin/tblgen

Then, run the program with the options given from the verbose output
(just cut and paste them) using the "run" command:

run {options}

When the program stops, just get a backtrace with the "bt" command.

When you've got that information, file a bug report at
http://llvm.org/bugs/, describe the circumstance (tblgen failure) and
paste in the backtrace. 

Once we have this information we should be able to track it down.

Thanks for the report.

Reid.
