[PATCH 09/11] libdl: Add support for trampolines
chrisj at rtems.org
chrisj at rtems.org
Tue Feb 5 01:43:02 UTC 2019
From: Chris Johns <chrisj at rtems.org>
- Trampolines or fixups for veneers provide long jump support
for instruciton sets that implement short relative address
branches. The linker provides trampolines when creating a
static image. This patch adds trampoline support to libdl
and the ARM architecture.
- The dl09 test requires enough memory so modules are outside
the relative branch instruction ranges for the architecture.
Updates #3685
