[llvm-dev] Size of produced binaries when compiling llvm & clang sources

[Manuel Yguel via llvm-dev]

Dear llvm developpers,
I followed the tutorial to build llvm and clang provided here:
https://clang.llvm.org/get_started.html

The sources are in sync with subversion repository, and I ended up with
more than 30GB of binaries in llvm/bin as shown at the end of this message.

I assume I did something wrong, but I did not find any entry in the doc
that helps me understand how to reduce the size of the binaries produced.

Is this normal ? Does any one has some hint to prevent this ?

Here are the sizes of the binaries:

1.9G clang-7
 1.6G clang-check
 1.2G clang-tidy
 1.1G opt
 1.1G bugpoint
 1.1G llvm-lto
 1.1G llvm-lto2
1018M llc
1015M c-index-test
 992M dsymutil
 992M llvm-isel-fuzzer
 989M llvm-opt-fuzzer

 937M llvm-c-test
 653M clang-import-test
