Have you disabled debugging?

No build type is debug but previously when I didn't pass
-DCMAKE_OSX_DEPLOYMENT_TARGET=10.10 -DCMAKE_OSX_SYSROOT=`xcrun options ,
with Debug build type size is very less. 7 GB is very unusual.
http://llvm.org/docs/GettingStarted.html according to this guide even with
Debug build type total size could go about 3 GB .

Well, for the build on Linux I certainly see 7GB w/ and 1GB w/o debug
symbols for the whole build directory -- that's with shared library.
For libLLVMCodeGen.so, it is 4MB vs 85MB. Compressed debug information
or differences in the unification can make some difference, but I am not
surprised by 25MB at all.
