From 04ff1e612ece7915c5c0f94c84f90f55e4c50059 Mon Sep 17 00:00:00 2001 From: Andreas Arnez Date: Thu, 16 Apr 2015 13:03:47 +0200 Subject: [PATCH] GDB tests for Go language support: remove unnecessary first breakpoint On s390x targets some of the Go test cases fail because the first breakpoint happens to be at the same spot as the breakpoint at main.main. When such a test case tries to continue to the first breakpoint, the program runs until the end instead, and the test fails like this: FAIL: gdb.go/handcall.exp: Going to first breakpoint (the program exited) This patch removes all the handling related to the first breakpoint in those cases. After applying the patch, the tests run successfully on s390x. gdb/testsuite/ChangeLog: * gdb.go/handcall.exp: Remove all logic related to the first breakpoint and rely on go_runto_main instead. * gdb.go/strings.exp: Likewise. * gdb.go/unsafe.exp: Likewise. * gdb.go/hello.exp: Likewise. Also rename the remaining breakpoint marker to "breakpoint 1". * gdb.go/handcall.go: Remove comment "set breakpoint 1 here". * gdb.go/strings.go: Likewise. * gdb.go/unsafe.go: Likewise. * gdb.go/hello.go: Likewise. Also remove the second occurrence of "set breakpoint 2 here" and rename the remaining breakpoint marker to "breakpoint 1". --- gdb/testsuite/ChangeLog | 15 +++++++++++++++ gdb/testsuite/gdb.go/handcall.exp | 8 -------- gdb/testsuite/gdb.go/handcall.go | 2 +- gdb/testsuite/gdb.go/hello.exp | 13 +++---------- gdb/testsuite/gdb.go/hello.go | 6 +++--- gdb/testsuite/gdb.go/strings.exp | 8 -------- gdb/testsuite/gdb.go/strings.go | 2 +- gdb/testsuite/gdb.go/unsafe.exp | 8 -------- gdb/testsuite/gdb.go/unsafe.go | 2 +- 9 files changed, 24 insertions(+), 40 deletions(-) diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index 91fd9a9..55a593a 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,18 @@ +2015-04-16 Andreas Arnez + + * gdb.go/handcall.exp: Remove all logic related to the first + breakpoint and rely on go_runto_main instead. + * gdb.go/strings.exp: Likewise. + * gdb.go/unsafe.exp: Likewise. + * gdb.go/hello.exp: Likewise.
