Felix Fietkau b050f87d13 gcc: prevent the use of LDRD/STRD on ARMv5TE These instructions are for 64-bit load/store. On ARMv5TE, the CPU requires addresses to be aligned to 64-bit. When misaligned, behavior is undefined (effectively either loads the same word twice on LDRD, or corrupts surrounding memory on STRD). On ARMv6 and newer, unaligned access is safe. Removing these instructions for ARMv5TE is necessary, because GCC ignores alignment information in pointers and does unsafe optimizations that have shown up as bugs in various places.

README

This is the buildsystem for the OpenWrt Linux distribution.

Please use "make menuconfig" to configure your appreciated
configuration for the toolchain and firmware.

You need to have installed gcc, binutils, bzip2, flex, python, perl
make, find, grep, diff, unzip, gawk, getopt, libz-dev and libc headers.

Run "./scripts/feeds update -a" to get all the latest package definitions
defined in feeds.conf / feeds.conf.default respectively
and "./scripts/feeds install -a" to install symlinks of all of them into
package/feeds/.

Use "make menuconfig" to configure your image.

Simply running "make" will build your firmware.
It will download all sources, build the cross-compile toolchain, 
the kernel and all choosen applications.

You can use "scripts/flashing/flash.sh" for remotely updating your embedded
system via tftp.

The OpenWrt system is documented in docs/. You will need a LaTeX distribution
and the tex4ht package to build the documentation. Type "make -C docs/" to build it.

To build your own firmware you need to have access to a Linux, BSD or MacOSX system
(case-sensitive filesystem required). Cygwin will not be supported because of
the lack of case sensitiveness in the file system.
