2015-12-08rl78: relaxation fixesDJ Delorie2-3/+55
Various fixes to linker relaxation. In general, we need to support relaxing every branch, even if we don't relax it in the assembler, so we can optionally defer relaxation to the linker. * elf32-rl78.c (rl78_offset_for_reloc): Add more relocs. (rl78_elf_relax_section): Add bc/bz/bnc/bnz/bh/bnh. Fix reloc choices. * config/rl78-parse.y: Make all branches relaxable via rl78_linkrelax_branch(). * config/tc-rl78.c (rl78_linkrelax_branch): Mark all relaxable branches with relocs. (options): Add OPTION_NORELAX. (md_longopts): Add -mnorelax. (md_parse_option): Support OPTION_NORELAX. (op_type_T): Add bh, sk, call, and br. (rl78_opcode_type): Likewise. (rl78_relax_frag): Fix not-relaxing logic. Add sk. (md_convert_frag): Fix relocation handling. (tc_gen_reloc): Strip relax relocs when not linker relaxing. (md_apply_fix): Defer overflow handling for anything that needs a PLT, to the linker. * config/tc-rl78.h (TC_FORCE_RELOCATION): Force all relocations to the linker when linker relaxing. * doc/c-rl78.texi (norelax): Add.

2015-12-07PowerPC ifunc with local symbolsAlan Modra3-123/+131
This fixes some cases where the linker would incorrectly error on plt relocs to local ifunc symbols. I've also tidied plt and ifunc handling for ppc64, where check_relocs was allowing for the possibility of plt calls via addr14/addr24 relocs but relocate_section was not. * elf32-ppc.c (ppc_elf_check_relocs): Don't error on local ifunc plt call. Wrap long lines. (ppc_elf_relocate_section): Wrap long lines. * elf64-ppc.c (ppc64_elf_check_relocs): Don't error on local ifunc plt calls. Move __tls_get_addr checks later. Don't create plt for addr14/addr24 relocs. (ppc64_elf_gc_sweep_hook): Adjust to suit check_relocs changes. (ppc64_elf_relocate_section): Correct local ifunc handling for PLT64, PLT32 and PLT16 relocs.
2015-12-07PR19323 memory allocation greater than 4GAlan Modra2-1/+15
On 32-bit targets, memory requested for program/section headers on a fuzzed binary can wrap to 0. A bfd_alloc of zero bytes actually returns a one byte allocation rather than a NULL pointer. This then leads to buffer overflows. Making this check unconditional triggers an extremely annoying gcc-5 warning. PR19323 * elfcode.h (elf_object_p): Check for ridiculous e_shnum and e_phnum values.

2015-12-04Optimize R_386_GOT32/R_386_GOT32X only if addend is 0H.J. Lu2-13/+17
Linker can't optimize R_386_GOT32 and R_386_GOT32X relocations if addend isn't 0. It isn't valid to convert movl foo@GOT+1(%ecx), %eax to leal foo@GOTOFF+1(%ecx), %eax nor to convert movq foo@GOTPCREL+1(%rip), %rax to leaq foo(%rip), %rax for x86-64.

2015-12-02addr2line vs. inlined C functions called from C++Alan Modra3-14/+31
In this case the inlined function doesn't have DW_AT_linkage_name in .debug_info, but the language is C++ so find_nearest_line goes looking in the symbol table. Since the function is inlined the enclosing non-inline function symbol is returned from _bfd_elf_find_function, which is wrong. This patch only uses a symbol if its address matches. PR binutils/19315 * dwarf2.c (_bfd_elf_find_function): Return symbol matched.

2015-12-01Properly check symbol defined by assignment in linker scriptH.J. Lu3-13/+25
Symbol defined by a linker assignment may have type bfd_link_hash_new or bfd_link_hash_undefined. And h->def_regular is always set. elf_i386_convert_load and elf_x86_64_convert_load should check h->def_regular as well as bfd_link_hash_undefined and bfd_link_hash_new to see if a symbol is defined by a linker script. bfd/ PR ld/19319 * elf32-i386.c (elf_i386_convert_load): Check h->def_regular instead of bfd_link_hash_new. * elf64-x86-64.c (elf_x86_64_convert_load): Likewise.
