Subject: linux-user: Move elf_core_copy_regs to ppc/elfload.c
X-Git-Tag: v10.2.0-rc1~119^2~67
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a67e20d629a849d9d9d5ef527963462cd0718e78;p=thirdparty%2Fqemu.git

linux-user: Move elf_core_copy_regs to ppc/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.
