From a31d2f068fa1384c505b540ea595d2d97813ba5f Mon Sep 17 00:00:00 2001 From: Yao Qi Date: Tue, 28 Jun 2016 12:02:35 +0100 Subject: [PATCH] Probe catch syscall support In 82075af2c14b1f8a54fa5796fb63f7ef23f98d9d (Implement 'catch syscall' for gdbserver), only x86 is supported, but the test can still be run on other linux targets, like aarch64 and ppc, with native-gdbserver. This causes many new fails. This patch removes the check on isnative and on target triplets. Instead, we can insert catch point, and resume the program to see whether catch syscall is supported or not. gdb/testsuite: 2016-06-28 Yao Qi * gdb.base/catch-syscall.exp: Remove check on isnative and target triplets. Start gdb, execute catch syscall, and continue. Check gdb's output to determine catch syscall is supported. --- gdb/testsuite/ChangeLog | 6 ++++ gdb/testsuite/gdb.base/catch-syscall.exp | 43 ++++++++++++++++-------- 2 files changed, 35 insertions(+), 14 deletions(-) diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index b7e30f5336..8ce6ee8902 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,9 @@ +2016-06-28 Yao Qi + + * gdb.base/catch-syscall.exp: Remove check on isnative and target + triplets.
