(amd64-sol2-tdep.o): Add dependencies. * amd64-sol2-tdep.c, config/i386/sol2-64.mh, config/i386/sol2-64.mt: New files. * i386-sol2-nat.c (amd64_sol2_gregset64_reg_offset, amd64_sol2_gregset32_reg_offset, _initialize_amd64_sol2_nat): New. (supply_gregset): Correct order of arguments to amd64_supply_native_gregset. (fill_gregset): Correct order of arguments to amd64_collect_native_gregset. * configure.host (i[34567]86-*-solaris2.1[0-9]*): Add new case. * configure.tgt (i[34567]86-*-solaris2.1[0-9]*): Likewise. * configure.in (*-*-solaris2.[[6789]]): Add *-*-solaris2.1[[0-9]] for definition of NEW_PROC_API. * configure: Regenerate. --- gdb/amd64-sol2-tdep.c | 125 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 125 insertions(+) create mode 100644 gdb/amd64-sol2-tdep.c (limited to 'gdb/amd64-sol2-tdep.c') diff --git a/gdb/amd64-sol2-tdep.c b/gdb/amd64-sol2-tdep.c new file mode 100644 index 0000000..f76e8a4 --- /dev/null +++ b/gdb/amd64-sol2-tdep.c @@ -0,0 +1,125 @@ +/* Target-dependent code for AMD64 Solaris. + + Copyright 2001, 2002, 2003, 2004 Free Software Foundation, Inc. + Contributed by Joseph Myers, CodeSourcery, LLC. + + This file is part of GDB. + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
