--- Comment #4 from René J.V. Bertin <rjvbertin at gmail dot com> --- The current support apparently has its glitches but above all it has nothing to do with gcc itself; it consists of using an existing `as` option to "Use the clang(1) integrated assembler instead of the GNU based system assembler". That's apparently the default for `as` so I don't understand why it doesn't invoke clang when used through gcc. > So, what is the correct configure option to let gcc use it by default? Write a wrapper script that just prepends or appends `-q` to the arguments and then calls the actual `as` command, and use that wrapper with the `--with-as` option? Crossing fingers that GCC itself will build... What I had in mind was calling `clang -cc1as` or even `llvm-as` directly, with the proper arguments. That ought to give better control over the generated object code than relying on a 3rd party (Apple) to implement the GNU -> clang argument translation.
