Subject: * alphabsd-tdep.h (alphanbsd_regset_from_core_section): New
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b0ca85736544b15d99386b9da5d39586a4c5eb97;p=binutils-gdb.git

* alphabsd-tdep.h (alphanbsd_regset_from_core_section): New
prototype.
* alphanbsd-tdep.c (alphanbsd_regset_from_core_section): Handle
a.out-style core file format here.  Make global.
(alphanbsd_regset_from_core_section): Remove.
(alphanbsd_sigtramp_offset): Make static.
(alphanbsd_aout_init_abi): Remove.
(alphanbsd_core_osabi_sniffer): Return GDB_OSABI_NETBSD_ELF for
a.out style core files.
(_initialize_alphanbsd_tdep): Do not register a handler for
GDB_OSABI_NETBSD_AOUT.
