clang+llvm uses gcc?

Clang Frontend

hi,

apparently I musunderstood something here. I'm trying to compile and run
the t.c from the getting started page
(http://clang.llvm.org/get_started.html).
Invoking "clang t.c" gives me an error that it failed because it has no
permissions to access gcc. Why is it calling gcc? I though tzhe clang
front end parses c into llvm IL and then the llvm generates a x86
binary, so where and especially why is gcc needed?

Sorry if this is actually a llvm amd not a clang related question, I'm
confused :slight_smile:

Thx!

On platforms where clang doesn't know how to properly call the
assembler and linker directly, the clang uses the gcc driver to
perform these tasks. if you pass "-S" to clang, it won't touch gcc.
