[PATCH] ld --disable-large-address-aware
- From: Christian Franke <Christian dot Franke at t-online dot de>
- To: binutils at sourceware dot org
- Date: Wed, 21 Aug 2013 22:32:52 +0200
- Subject: [PATCH] ld --disable-large-address-aware
On Cygwin --large-address-aware is always set by gcc built in specs. A
few programs are not compatible with --large-address-aware but there is
no easy way to revert this option.
This patch adds --disable-large-address-aware.

* emultempl/pe.em: Add --disable-large-address-aware option.
* ld.texinfo (--disable-large-address-aware): Add documentation.
