+
+ * elf32-m32c.c (m32c_elf_check_relocs): Use bfd_make_section
+ "anyway" variant when creating .plt.
+ (m32c_elf_relax_plt_section): Remove redundant test and unused param.
+ (m32c_elf_relax_section): Test SEC_LINKER_CREATED before calling
+ m32c_elf_relax_plt_section.
+ * elfxx-mips.c (mips_elf_create_got_section): Use make anyway variant
+ when creating .got and .got.plt.
+ (_bfd_mips_elf_final_link): Likewise for .rtproc, and use
+ bfd_get_linker_section.
+ * sunos.c: Similarly throughout.
+
2012-07-01 Andreas Schwab <schwab@linux-m68k.org>
* elf.c (_bfd_elf_make_section_from_shdr): Fix typo in error
