Subject: linux-user: Move elf_core_copy_regs to sh4/elfload.c
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a4ea8c30e7c8ae49e2e50e2c410581ad53c3e1fb;p=thirdparty%2Fqemu.git

linux-user: Move elf_core_copy_regs to sh4/elfload.c

Move elf_core_copy_regs to elfload.c.
Move HAVE_ELF_CORE_DUMP, ELF_NREGS, target_elf_gregset_t to target_elf.h.
For now, duplicate the definitions of target_elf_greg_t and tswapreg.
