(i386fbsd_sigtramp_start, i386fbsd_sigtramp_end, i386fbsd_sc_reg_offset, i386fbsdaout_init_abi, i386fbsd_init_abi, i386fbsd4_sc_reg_offset, i386fbsd4_init_abi): Move here from i386bsd-tdep.c. (_initialize_i386fbsd_tdep): New function. (i386fbsd_r_reg_offset, i386fbsd4_r_reg_offset): New varibles. (i386fbsdaout_init_abi): Initialize TDEP->gregset_reg_offset, TDEP->gregset_num_regs, TDEP->sizeof_gregset and TDEP->sizeof_fpregset. Use ARRAY_SIZE to initialize TDEP->sc_num_regs. (i386fbsd4_init_abi): Initialize TDEP->gregset_reg_offset, TDEP->gregset_num_regs and TDEP->sizeof_gregset. Use ARRAY_SIZE to initialize TDEP->sc_num_regs. * i386bsd-tdep.c (i386fbsd_sigtramp_start, i386fbsd_sigtramp_end, i386fbsd_sc_reg_offset, i386fbsdaout_init_abi, i386fbsd_init_abi, i386fbsd4_sc_reg_offset, i386fbsd4_init_abi): Remove. (_initialize_i386bsd_tdep): Don't register FreeBSD a.out and FreeBSD ELF OS/ABI's here. * Makefile.in (ALLDEPFILES): Add i386fbsd-tdep.c. (i386fbsd-tdep.o): New target. * config/i386/fbsd.mt (TDEPFILES): Add i386fbsd-tdep.o. * config/i386/fbsd64.mt (TDEPFILES): Add i386fbsd-tdep.o. --- gdb/i386bsd-tdep.c | 103 +---------------------------------------------------- 1 file changed, 1 insertion(+), 102 deletions(-) (limited to 'gdb/i386bsd-tdep.c') diff --git a/gdb/i386bsd-tdep.c b/gdb/i386bsd-tdep.c index 94d68600fee..aa3a7e40a7d 100644 --- a/gdb/i386bsd-tdep.c +++ b/gdb/i386bsd-tdep.c @@ -1,4 +1,5 @@ /* Target-dependent code for i386 BSD's. + Copyright 2001, 2002, 2003 Free Software Foundation, Inc.
