           Summary: stage2 and stag3 of clang are not identical
           Product: clang
           Version: trunk
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++

I am bootstapping clang, and in theory stage2 and stage should be identical
binaries (at least on linux).

Binaries are different for the last 3 weeks here (Fedora 12, 32bit,
bootstrapping from gcc-4.4.3). I am compiling out of source using cmake.

[elcuco at pinky ~/src/llvm] ls -l bootstrap-stage-{2,3}/bin/clang
-rwxrwxr-x. 1 elcuco elcuco 24576970 2010-05-17 20:14
-rwxrwxr-x. 1 elcuco elcuco 24580575 2010-05-17 20:35

I attach here the build script I used, just save it under the root of your llvm
checkout, and it will create 3 new directories, + bootstrap.log file with all
the build log. not tested on mac, but I assume it will work as well.
