File gdb-testsuite-handle-sigill-in-two-gdb.arch-powerpc-test-cases.patch of Package gdb
[gdb/testsuite] Handle SIGILL in two gdb.arch powerpc test-cases On powerpc64le-linux, with test-case gdb.arch/powerpc-addpcis.exp I run into SIGILL: ... (gdb) PASS: gdb.arch/powerpc-addpcis.exp: get hexadecimal valueof "$r3" stepi^M ^M Program terminated with signal SIGILL, Illegal instruction.^M The program no longer exists.^M (gdb) PASS: gdb.arch/powerpc-addpcis.exp: set r4 ... because it's a power9 insn, and I'm running on a power8 machine. Fix this by handling the SIGILL. Likewise in gdb.arch/powerpc-lnia.exp. Tested on powerpc64le-linux. --- gdb/testsuite/gdb.arch/powerpc-addpcis.exp | 14 +++++++++++++- gdb/testsuite/gdb.arch/powerpc-lnia.exp | 14 +++++++++++++- 2 files changed, 26 insertions(+), 2 deletions(-) diff --git a/gdb/testsuite/gdb.arch/powerpc-addpcis.exp b/gdb/testsuite/gdb.arch/powerpc-addpcis.exp index d1bc7f49ce6..ff7052ce475 100644 --- a/gdb/testsuite/gdb.arch/powerpc-addpcis.exp +++ b/gdb/testsuite/gdb.arch/powerpc-addpcis.exp @@ -50,7 +50,19 @@ gdb_breakpoint $bp1 gdb_breakpoint $bp2 gdb_breakpoint $bp3 -gdb_test "stepi" "" "set r3 " +set insn_supported 1 +gdb_test_multiple "stepi" "set r3" { + -re "Program received signal SIGILL, Illegal instruction\\..*" { + set insn_supported 0 + } + -re -wrap "" { + pass $gdb_test_name + } +} +if { ! $insn_supported } { + unsupported "illegal instruction" + return +} set check_r3 [get_hexadecimal_valueof "\$r3" "default0"] gdb_test "stepi" "" "set r4" set check_r4 [get_hexadecimal_valueof "\$r4" "default0"] diff --git a/gdb/testsuite/gdb.arch/powerpc-lnia.exp b/gdb/testsuite/gdb.arch/powerpc-lnia.exp index 0f56d834046..4ab4f8d92be 100644 --- a/gdb/testsuite/gdb.arch/powerpc-lnia.exp +++ b/gdb/testsuite/gdb.arch/powerpc-lnia.exp @@ -54,7 +54,19 @@ gdb_breakpoint $bp3 # single-step through the lnia instructions, and retrieve the # register values as we proceed. -gdb_test "stepi" "" "set r3" +set insn_supported 1 +gdb_test_multiple "stepi" "set r3" { + -re "Program received signal SIGILL, Illegal instruction\\..*" { + set insn_supported 0 + } + -re -wrap "" { + pass $gdb_test_name + } +} +if { ! $insn_supported } { + unsupported "illegal instruction" + return +} set check_r3 [get_hexadecimal_valueof "\$r3" "default0"] gdb_test "stepi" "" "set r4" set check_r4 [get_hexadecimal_valueof "\$r4" "default0"]
