From: Marcin Kościelnicki Date: Tue, 10 Nov 2015 08:52:29 +0000 (+0100) Subject: gdb/testsuite/gdb.trace: Deduplicate pcreg/spreg/fpreg. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6e7675a70f5a375159f94354fb6f38519303a73d;p=binutils-gdb.git gdb/testsuite/gdb.trace: Deduplicate pcreg/spreg/fpreg. These variables were used in many gdb.trace tests. Keep them in one place, to reduce work needed for new targets. gdb/testsuite/ChangeLog: * gdb.trace/backtrace.exp: Use global fpreg/spreg definition, add $ in front. * gdb.trace/change-loc.exp: Use global pcreg definition. * gdb.trace/collection.exp: Use global pcreg/fpreg/spreg definition. * gdb.trace/entry-values.exp: Use global spreg definition, add $ in front. * gdb.trace/mi-trace-frame-collected.exp: Use global pcreg definition. * gdb.trace/pending.exp: Likewise. * gdb.trace/report.exp: Use global pcreg/fpreg/spreg definition. * gdb.trace/trace-break.exp: Likewise. * gdb.trace/trace-condition.exp: Use global pcreg definition, add $ in front. * gdb.trace/unavailable.exp: Use global pcreg/fpreg/spreg definition. * gdb.trace/while-dyn.exp: Use global fpreg definition, add $ in front. * lib/trace-support.exp: Define fpreg, spreg, pcreg variables. --- diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index dfc9b776609..0f041094576 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,22 @@ +2015-11-10 Marcin Kościelnicki + + * gdb.trace/backtrace.exp: Use global fpreg/spreg definition, add $ + in front. + * gdb.trace/change-loc.exp: Use global pcreg definition. + * gdb.trace/collection.exp: Use global pcreg/fpreg/spreg definition. + * gdb.trace/entry-values.exp: Use global spreg definition, add $ + in front. + * gdb.trace/mi-trace-frame-collected.exp: Use global pcreg definition. + * gdb.trace/pending.exp: Likewise. + * gdb.trace/report.exp: Use global pcreg/fpreg/spreg definition. + * gdb.trace/trace-break.exp: Likewise. + * gdb.trace/trace-condition.exp: Use global pcreg definition, add $ + in front. + * gdb.trace/unavailable.exp: Use global pcreg/fpreg/spreg definition. + * gdb.trace/while-dyn.exp: Use global fpreg definition, add $ + in front. + * lib/trace-support.exp: Define fpreg, spreg, pcreg variables. + 2015-11-09 Joel Brobecker * gdb.ada/fin_fun_out: New testcase. diff --git a/gdb/testsuite/gdb.trace/backtrace.exp b/gdb/testsuite/gdb.trace/backtrace.exp index f69089b7e5a..c1720294162 100644 --- a/gdb/testsuite/gdb.trace/backtrace.exp +++ b/gdb/testsuite/gdb.trace/backtrace.exp @@ -140,23 +140,9 @@ gdb_trace_setactions "8.6: setup TP to collect regs, args, and locals" \ "$tdp4" \ "collect \$regs, \$args, \$locs" "^$" -if [is_amd64_regs_target] { - set fpreg "\$rbp" - set spreg "\$rsp" -} elseif [is_x86_like_target] { - set fpreg "\$ebp" - set spreg "\$esp" -} elseif [is_aarch64_target] { - set fpreg "\$x29" - set spreg "\$sp" -} else { - set fpreg "\$fp" - set spreg "\$sp" -} - gdb_trace_setactions "8.6: setup TP to collect stack mem cast expr" \ "$tdp6" \ - "collect $fpreg, \(\*\(void \*\*\) \($spreg\)\) @ 64" "^$" + "collect \$$fpreg, \(\*\(void \*\*\) \(\$$spreg\)\) @ 64" "^$" gdb_test_no_output "tstart" "" diff --git a/gdb/testsuite/gdb.trace/change-loc.exp b/gdb/testsuite/gdb.trace/change-loc.exp index a417ef99751..97c604ef48e 100644 --- a/gdb/testsuite/gdb.trace/change-loc.exp +++ b/gdb/testsuite/gdb.trace/change-loc.exp @@ -58,14 +58,6 @@ if { ![gdb_target_supports_trace] } then { return -1 } -if [is_amd64_regs_target] { - set pcreg "rip" -} elseif [is_x86_like_target] { - set pcreg "eip" -} else { - set pcreg "pc" -} - # Set tracepoint during tracing experiment. diff --git a/gdb/testsuite/gdb.trace/collection.exp b/gdb/testsuite/gdb.trace/collection.exp index 69ad6ee66d4..987fb6f900d 100644 --- a/gdb/testsuite/gdb.trace/collection.exp +++ b/gdb/testsuite/gdb.trace/collection.exp @@ -36,24 +36,6 @@ if {[prepare_for_testing $testfile.exp $testfile $srcfile {debug nowarnings}]} { set ws "\[\r\n\t \]+" set cr "\[\r\n\]+" -if [is_amd64_regs_target] { - set fpreg "rbp" - set spreg "rsp" - set pcreg "rip" -} elseif [is_x86_like_target] { - set fpreg "ebp" - set spreg "esp" - set pcreg "eip" -} elseif [is_aarch64_target] { - set fpreg "x29" - set spreg "sp" - set pcreg "pc" -} else { - set fpreg "fp" - set spreg "sp" - set pcreg "pc" -} - # # Utility procs # diff --git a/gdb/testsuite/gdb.trace/entry-values.exp b/gdb/testsuite/gdb.trace/entry-values.exp index 0cf56151fc3..07aaa228eab 100644 --- a/gdb/testsuite/gdb.trace/entry-values.exp +++ b/gdb/testsuite/gdb.trace/entry-values.exp @@ -214,20 +214,12 @@ if ![gdb_target_supports_trace] { gdb_test "trace foo" "Tracepoint $decimal at .*" -if [is_amd64_regs_target] { - set spreg "\$rsp" -} elseif [is_x86_like_target] { - set spreg "\$esp" -} else { - set spreg "\$sp" -} - # Collect arguments i and j.
