[PATCH] add armelf_uclinux linker target
- To: binutils at sources dot redhat dot com
- Subject: [PATCH] add armelf_uclinux linker target
- From: Adrian von Bidder <avbidder at acter dot ch>
- Date: Fri, 02 Nov 2001 10:07:50 +0100
Hi!
The attached patch ads an armelf_uclinux linker target. Essentially it
just puts the .rodata section at the start of the data segment instead
of a section of its own.
I just took the changes that were made to binutils-2.9.5 (on the
embedded debian home page) and ported them to 2.11.2.
comments?
greets from Zürich
