This adds support for ".localentry 1", a new st_other STO_PPC64_LOCAL_MASK encoding that signifies a function with a single entry point like ".localentry 0", but unlike a ".localentry 0" function does not preserve r2. include/ * elf/ppc64.h: Specify byte offset to local entry for values of two to six in STO_PPC64_LOCAL_MASK. Clarify r2 return value for such functions when entering via global entry point. Specify meaning of a value of one in STO_PPC64_LOCAL_MASK. bfd/ * elf64-ppc.c (ppc64_elf_size_stubs): Use a ppc_stub_long_branch_r2off for calls to symbols with STO_PPC64_LOCAL_MASK bits set to 1. gas/ * config/tc-ppc.c (ppc_elf_localentry): Allow .localentry values of 1 and 7 to directly set value into STO_PPC64_LOCAL_MASK bits. ld/testsuite/ * ld-powerpc/elfv2.s: Add .localentry f5,1 testcase. * ld-powerpc/elfv2exe.d: Update. * ld-powerpc/elfv2so.d: Update.
