Subject: v850: improve linker scripts for relocatable linking
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b6b2252830dc0431c82aee695055acfb7f341722;p=thirdparty%2Fbinutils-gdb.git

v850: improve linker scripts for relocatable linking

Quite a few constructs where unconditional when they should take
$RELOCATING into account. The original observation was that output of
"ld -r" had .text start at 0x00100000.
