llvm dev - Sep 2009 - [LLVMdev] TOT broken

The buildbots are unhappy again.  :-(

Specifically, the "llvm-gcc-i386-darwin9" buildbot here at Apple last
compiled TOT successfully yesterday morning (31aug); that was revision  
80586.  By revision 80589, the bootstrap failed due to a miscompare,  
and by revision 80610, it's aborting while compiling little pieces of  
libgcc.

80586	built O.K. (about 8AM, Pacific Standard Time, on Monday 31aug)
...
80589	bootstrap miscompare (about one hour after 80586)
...
80610	abort()s while compiling libgcc (about two hours after 80589)
...
80717	(current as I write this, on Tuesday 01sep) still broken

I realize that everyone is busy, but I think TOT has been broken long  
enough.  Would everyone that committed any patches yesterday please  
check your work with a clean make of TOT?

Thank you in advance,

stuart

Yes, this is pretty unacceptable IMHO.

I would go revert crazy if I knew what to hit, unfortunately I don't.

Currently I believe there are two problems, a CallGraphSCC assert
which is firing everywhere (including the clang test suite, *cough*).
This started with 80698. Chris is working on this (if it isn't already
fixed).

The bootstrap comparison failures are being looked at by Devang.

For those not seeing the failures on the Google build bots. That's
because they're not building llvm-gcc with bootstrap (or, indeed, at
all).

Fixed in r80724.

Yes, I am investigating this. As you say, the buildbots were happy
Monday morning, but investigation leads me to combination of patches
committed last week and first week of August. The bug was hiding until
Monday. So... stay tuned.
