[Chapel-bugs] Clang arguments passed in wrong way when using --ccflags

[Przemek L. <pop...@gm...>]

There is a problem associated with passing options to backend C compiler
when it is clang (in case of gcc this works fine). Clang receives options
as one string being concatenation of all options and doesn't parse this.

chpl --ccflags "-mllvm -use-cfl-aa" --llvm test.chpl
and
chpl --ccflags -mllvm --ccflags -use-cfl-aa --llvm test.chpl

Give:

error: unknown argument: '-mllvm -use-cfl-aa'

Note that I have to use --llvm flag so that the backend compiler becomes
clang (it's gcc without this flag).

chpl --ccflags "-mllvm -use-cfl-aa" test.chpl

Gives:

gcc: error: unrecognized command line option ‘-mllvm’

Which is fine.

I checked both gcc and clang compiler errors just to make sure:

gcc "-mllv -use-cfl-aa"
gcc: error: unrecognized command line option ‘-mllv -use-cfl-aa’

clang "-mllv -use-cfl-aa"
clang: error: unknown argument: '-mllv -use-cfl-aa'

Is there any workaround?
