           Summary: I'm impatient, please make llvm-test faster
           Product: Test Suite
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Nightly Tester
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: sabre at nondot.org


Ideas:

1. Instead of using llvm-gcc -S -emit-llvm + llvm-as to get to the .rbc file for each.c file, just use llvm-
gcc -c -emit-llvm.
2. To get from linked.rbc to linked.bc, we currently invoke llvm-dis, then 'gccas' (a shell script which 
invokes llvm-dis then opt).  It would be much better to just run opt!

Both of these would significantly reduce the disk I/O, disk space required, and cpu time requirements for 
running llvm-test.
