Subject: [PATCH] Pass more options to the assembler.
Date: Wed, 01 Aug 2007 17:51:00 -0000	[thread overview]
Message-ID: <20070801175134.GR18317@lios> (raw)

The driver should pass -w, -I and -v to the gnu assembler. 

If the user requests -w (no warnings), then -W (no warnings) should be
passed to the assembler. The passing of -I options to the assembler
would allow .include and #include to share directories. Lastly, if the
compiler is being verbose, the assembler should list a version string,
so pass -v to the assembler aswell.

Tested on arm-none-eabi, and i686-pc-linux-gnu without regressions.

OK for mainline?
