The key here is that the targ= et will be Arm, but uname will still report AArch64. Use this test to disable gdb.base/break-interp.exp, as this test currently generates 132 sequential timeouts. This change will enable the Arm buildbot worker setup to run the testsuite within a reasonable timeframe. gdb/testsuite/ChangeLog: 2019-08-09 Alan Hayward * gdb.base/break-interp.exp: Skip if is AArch32 on AArch64 target. * lib/future.exp (gdb_find_uname): New procedure. * lib/gdb.exp (is_aarch32_on_aarch64_target): Likewise. --- gdb/testsuite/gdb.base/break-interp.exp | 3 ++- gdb/testsuite/lib/future.exp | 10 ++++++++++ gdb/testsuite/lib/gdb.exp | 20 ++++++++++++++++++++ 3 files changed, 32 insertions(+), 1 deletion(-) diff --git a/gdb/testsuite/gdb.base/break-interp.exp b/gdb/testsuite/gdb.ba= se/break-interp.exp index d6da653529..6a366db49f 100644 --- a/gdb/testsuite/gdb.base/break-interp.exp +++ b/gdb/testsuite/gdb.base/break-interp.exp @@ -15,7 +15,8 @@ =20 # This test only works on GNU/Linux. if { ![isnative] || [is_remote host] || [use_gdb_stub] - || ![istarget *-linux*] || [skip_shlib_tests]} { + || ![istarget *-linux*] || [skip_shlib_tests] + || [is_aarch32_on_aarch64_target]} { continue } =20 diff --git a/gdb/testsuite/lib/future.exp b/gdb/testsuite/lib/future.exp index 122e652858..d43dd95904 100644 --- a/gdb/testsuite/lib/future.exp +++ b/gdb/testsuite/lib/future.exp @@ -172,6 +172,16 @@ proc gdb_find_eu-unstrip {} { return $eu_unstrip } =20 +proc gdb_find_uname {} { + global UNAME_FOR_TARGET + if [info exists UNAME_FOR_TARGET] { + set uname $UNAME_FOR_TARGET + } else { + set uname [transform uname] + } + return $uname +} + proc gdb_default_target_compile {source destfile type options} { global target_triplet global tool_root_dir diff --git a/gdb/testsuite/lib/gdb.exp b/gdb/testsuite/lib/gdb.exp index edc8dfcdfd..ffdb763104 100644 --- a/gdb/testsuite/lib/gdb.exp +++ b/gdb/testsuite/lib/gdb.exp @@ -2629,6 +2629,26 @@ proc is_aarch64_target {} { return [expr ![is_aarch32_target]] } =20 +# Return 1 if this target is AArch32/Arm running on AArch64. + +proc is_aarch32_on_aarch64_target {} { + if { ![istarget "arm*-*-*"] } { + return 0 + } + + set uname_program [gdb_find_uname] + set command "exec $uname_program -m" + verbose -log "command is $command" + set result [catch $command output] + verbose -log "result is $result" + verbose -log "output is $output" + if {$result =3D=3D 0 && [string match $output "aarch64"]} { + return 1 + } + return 0 +} + + # Return 1 if displaced stepping is supported on target, otherwise, return= 0. proc support_displaced_stepping {} { =20 --=20 2.20.1 (Apple Git-117)
