Glibc with Clang/LLVM

Has anybody able to compile glibc with newer version of clang/llvm. If its not possible is there any patch to fix this problem.

Kostya was working on this recently, with help from Roland.

Last time I checked there were ~ 10 nested functions and 4 instances of VLAIS.
I am sending patches one by one but the review process is taking time.
The last one:
Help with other nested functions and especially VLAIS is more than welcome.

Once these are fixes, some fixes in configure/make will need to be done –
configure simply fails with CC=clang and once this is bypassed there are some linking issues (haven’t investigated yet).

I used fresh clang with "-fno-integrated-as -fheinous-gnu-extensions -D__EXCEPTIONS "
