[cfe-dev] Compiling clang with llvm-gcc

[Jean-Daniel Dupas]

Hello,

I'm compiling clang with llvm-gcc-4.2 on Snow Leopard (i686-apple- 
darwin10-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5646)  
(LLVM build 2118)).
clang and llvm are compiled as a 64 bit binaries (x86_64).

When building a debug version, it works well, but when I build without  
assert and optimized, clang is badly broken. It often crashes and this  
is  the 'make test' result:

--- Running clang tests for x86_64-apple-darwin10.0.0 ---
[..]
   Expected Passes    : 1496
   Expected Failures  : 15
   Unexpected Failures: 118

Unexpected failures append in many test sections  (Analyze, Codegen,  
Frontend, Preprocess, Sema, etc…).

Is it a known issue  ? Is there any chance it works better if I  
compile llvm-gcc myself using a newer codebase ?

Thanks
