From: Carl Love Date: Tue, 26 Apr 2022 19:23:49 +0000 (+0000) Subject: GDB PowerPC record test cases for ISA 2.06 and ISA 3.1 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1bc0d95eada3be8e73667fac0d4c0018366b985c;p=binutils-gdb.git GDB PowerPC record test cases for ISA 2.06 and ISA 3.1 This patch adds PowerPC specific tests to verify recording of various instructions. The first test case checks the ISA 2.06 lxvd2x instruction. The second test case tests several of the ISA 3.01 instructions. Specifically, it checks the word and prefixed instructions and some of the Matrix Multiply Assist (MMA) instructions. The patch has been run on both Power 10 and Power 9 to verify the ISA 2.06 test case runs on both platforms without errors. The ISA 3.1 test runs without errors on Power 10 and is skipped as expected on Power 9. --- diff --git a/gdb/testsuite/gdb.reverse/ppc_record_test_isa_2_06.c b/gdb/testsuite/gdb.reverse/ppc_record_test_isa_2_06.c new file mode 100644 index 00000000000..45e58413da2 --- /dev/null +++ b/gdb/testsuite/gdb.reverse/ppc_record_test_isa_2_06.c @@ -0,0 +1,39 @@ +/* This testcase is part of GDB, the GNU debugger. + + Copyright 2012-2022 Free Software Foundation, Inc. + + 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 3 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.
