[llvm-dev] Unable to build and install LLVM on Mac OSX 10.11

[Sumedh Arani via llvm-dev]

Arani:~ Sumedh$ xcrun clang -v

Apple LLVM version 7.3.0 (clang-703.0.31)

Target: x86_64-apple-darwin15.4.0

Thread model: posix

InstalledDir:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin



Greetings!!


I followed the instructions given by you to the letter and it worked like a
charm.


Just this time I didn't download compiler-rt or any other extra tools.


How can I upgrade to them??


And also how can I change my version of clang to the one which has been
built now? As on doing clang --version or xcrun clang -v still gives the
version as the one that comes pre built with apple's machine.


Thank you.


Yours sincerely,

Sumedh Arani.
