We currently don't do a good job of diagnosing inputs that would require dynamic relocations to be applied to read only segments. I am about to improve lld in that area, but unfortunately we developed tests that depend on the current behavior. To make clear what is actually changing, this first patch just updates tests to not depend on the current behavior. In most cases this just means using a rw section instead of a ro one, but that unfortunately changes many addresses. llvm-svn: 268145	2016-04-30 00:49:10 +00:00

lld: Default image base address to 0x200000 on x86-64

Align to the large page size (known as a superpage or huge page).

Don't depend on lld creating relocations in ro segments.

We currently don't do a good job of diagnosing inputs that would require
dynamic relocations to be applied to read only segments.

I am about to improve lld in that area, but unfortunately we developed
tests that depend on the current behavior.

To make clear what is actually changing, this first patch just updates
tests to not depend on the current behavior. In most cases this just
means using a rw section instead of a ro one, but that unfortunately
changes many addresses.
