New Revision: 323031
URL: https://svnweb.freebsd.org/changeset/base/323031
Log:
Compile reloc.o with -fno-jump-tables on MIPS.
In particular, the switch statement on the type of dynamic entries
in _rtld_relocate_nonplt_self() needs to not use a jump table since
jump tables on MIPS use local GOT entries which aren't initialized
until after this loop.
