Doc Text:	Large and/or high-address programs now link and execute correctly on AArch64 Previously, incorrect code in the linker could result in incorrect branch stubs being generated. Consequently, programs that were very big or if the programmer coded parts of the program to exist at a very high address, failed to link. The bug has been fixed and the correct kind of branch stub is now selected.

Description David Abdurachmanov 2015-07-15 15:10:50 EDT

Description of problem:

There are two cases then ld.bfd does not insert veneers on aarch64:
- "the target symbol and relocated place are in separate sections"
- if you are building a shared library and a function call goes through PLT stub. PLT stub ends up outside of +/-128MB range.

Version-Release number of selected component (if applicable):

The problems are present in trunk (last tested July 13) of binutils.

How reproducible:

All the details are in referenced PR in sourceware bugzilla.
