This change seems to affect the weight assigned to the LiveIntervals for
each virtual register which in turn changes the allocation order.
It would be my expectation that LLVM should generate identical code for a
source file with and without debu...

[RFC] klibc add minimal mntent.h
...s patch is a first step towards a mntent.h
we'll need it anyways later for mdadm support.
it allows to compile util-linux-ng mount against klibc.
due to the missing features there is a severe size difference:

[LLVMdev] Boostrap Failure -- Expected Differences?
The saga continues.
I've been tracking the interface changes and merging them with
the refactoring work I'm doing. I got as far as building stage3
of llvm-gcc but the object files from stage2 and stage3 differ:
warning: ./cc1-checksum.o differs
warning: ./cc1plus-checksum.o differs
(Are the above two ok?)
The list below is clearly bad. I think it's every object file in
the
