2015-09-16Fix slowdown in ld -r for most common case of out-of-order relocsAlan Modra2-15/+58
I chose insertion sort since relocs are mostly sorted, but there is a common case we can handle better; A run of relocs put out of order due to not linking input files in order. PR 18867 * elflink.c (elf_link_adjust_relocs): Modify insertion sort to insert a run. Return status in case of malloc failure. Adjust callers.

2015-09-01Skip PLT for function pointer initializationH.J. Lu3-17/+150
We use its PLT entry to initialize function pointer at run-time. If there is no other usage for the PLT entry, we can generate run-time function pointer relocations in read-write section, which can be resolved by dynamic linker, to initialize function pointers. It avoids the extra indirect branch overhead in PLT. bfd/ PR ld/18900 * elf32-i386.c (elf_i386_link_hash_entry): Add func_pointer_refcount. (elf_i386_link_hash_newfunc): Clear func_pointer_refcount.

2015-09-01ppc64 out-of-line register save/restore functionsAlan Modra2-49/+171
Don't emit long branch or plt branch stubs to save/restore functions. Copy them instead. The problem is that plt branch stubs currently trash r12, one of the parameters to some of the save/restore functions, and there is no free register available to use instead of r12. 6f20ed8a is prerequisite for this patch.

2015-08-31Optimise PowerPC64 r2 adjusting stubsAlan Modra2-12/+28
Sometimes these stubs don't need to change the low 16-bits of r2, so in that case omit a useless addi r2,r2,0 insn. Also, change the get_r2off error return from 0 to -1 since 0 is a valid return for ELFv2 -R objects. * elf64-ppc.c (get_r2off): Return -1 on error. (ppc_build_one_stub): Adjust for get_r2off change.
