On SPARC, .plt is both writeable and executable. The current way sections are sorted means that lld puts it after .data/.bss. but it really needs to be close to .test to make sure branches into .plt don't overflow. I'd argue that because .bss is supposed to come last on all architectures, we should change the default sort order such that writable and executable sections come before sections that are just writeable. read-only executable sections should still come after sections that are just read-only of course. This diff makes this change. llvm-svn: 304008
