From 21b9b5b1ca05619ad399b3d746e71e844ab1bb2b Mon Sep 17 00:00:00 2001 From: Michael Snyder Date: Tue, 8 Jan 2002 01:00:10 +0000 Subject: [PATCH] 2002-01-07 Michael Snyder * gdb.base/huge.exp: New test. Print a very large target data object. (skip_huge_test): New test variable. Define if you want to skip this test. The test reads an 8 megabyte data object from the target, so it might be very time consuming on remote targets with a slow connection. * gdb.base/huge.c: New file. Test case for above. --- gdb/testsuite/ChangeLog | 8 +++++ gdb/testsuite/gdb.base/huge.c | 19 +++++++++++ gdb/testsuite/gdb.base/huge.exp | 57 +++++++++++++++++++++++++++++++++ 3 files changed, 84 insertions(+) create mode 100644 gdb/testsuite/gdb.base/huge.c create mode 100644 gdb/testsuite/gdb.base/huge.exp diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index 5f32bc59cc5..00557c58e59 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,11 @@ +2002-01-07 Michael Snyder + + * gdb.base/huge.exp: New test.
