Alexandre Oliva writes:
This patch adds code to uClibc to support a new ABI designed for the
FR-V architecture, that enables text segments of executables and
shared libraries to be shared by multiple processes on an OS such as
uClinux, that can run on FR-V processors without an MMU.
Patches for binutils and GCC have just been posted in the
corresponding mailing lists. The binutils patch was approved,
but there's one additional patch pending review, that I posted
this week. An updated GCC patch will be posted to
gcc-patches@gcc.gnu.org as soon as I complete testing (I used a
known-good compiler to test the uClibc patch below).
Since the existing dynamic loader code didn't support independent
relocation of segments, it required changes that were somewhat
extensive. I've added a number of new machine-specific macros to try
to keep the platform and ABI-specific details outside the generic
code. I hope this is not a problem.
