3Subject: Fixup debug_loc sections after linker relaxation
4
5Adds a new reloctype R_MICROBLAZE_32_NONE, used for passing
6reloc info from the assembler to the linker when the linker
7manages to fully resolve a local symbol reference.
8
9This is a workaround for design flaws in the assembler to
10linker interface with regards to linker relaxation.

3Subject: upstream change to garbage collection sweep causes mb regression
4
5Upstream change for PR13177 now clears the def_regular during gc_sweep of a
6section. (All other archs in binutils/bfd/elf32-*.c received an update
7to a warning about unresolvable relocations - this warning is not present
8in binutils/bfd/elf32-microblaze.c, but this warning check would not
9prevent the error being seen)
10
11The visible issue with this change is when running a c++ application
12in Petalinux which links libstdc++.so for exception handling it segfaults
13on execution.
14
15This does not occur if static linking libstdc++.a, so its during the
16relocations for a shared lib with garbage collection this occurs
