New Revision: 328939
URL: https://svnweb.freebsd.org/changeset/base/328939
Log:
Use a workaround to compile the crt init functions correctly with clang.
The MIPS assembly parser treats forward-declared local symbols as global
symbols. This results in CALL16 relocations being used against local
(private) symbols which then fail to resolve when linking binaries.
Add .local to force the init and fini functions to be treated as local as
a workaround.
