Rumor has it that "people familiar with the matter" said Apple will kill in Xcode 4.4.
llvm-gcc was already a deal breaker for me. I maintain (or not?) build scripts that allow one to compile Code Sourcery g++ for embedded Linux to natively run on Mac OS X. Here are the details:
https://github.com/UnhandledException/ARMx/wiki/Sourcery-G++-Lite-for-ARM-GNU-Linux-(2009q3-67)-for-Mac-OS-X
I am assuming that gcc likes to be compiled only with gcc (may be someone has tried clang to compile gcc?, don't know).
The XCode 4.0 (or 4.1?) shipped with a version of llvm-gcc that failed to compile gcc and crashed with an out-of-memory error---yeah, I know, I should have filed a bug report, but I didn't :-( I had to specifically set my compiler to point to gcc-4.2 to get things to compile correctly. Now that gcc is gone, and only llvm-gcc and clang are available, I am too scared to even try.
When llvm-gcc is finally gone, it will make it even harder for me to compile a cross toolchain on the Mac. With llvm-gcc around, I hope to be able to update my scripts someday and publish it for Lion (the current ones are for SL). With only clang, I _may_ be able to get the toolchain to compile _only_ if I am willing to lose all of my hair over it!
