2014-12-29Sanitize input_interrupt outputSergio Durigan Junior2-3/+19
Hi, This patch is a follow-up of the following discussions: <https://sourceware.org/ml/gdb-patches/2014-12/msg00421.html> <https://gcc.gnu.org/ml/gcc-patches/2014-12/msg01293.html> input_interrupt is currently emiting non-printable characters, which is confusing the dg-extract-results.sh script. This is obviously not a good thing, and, by following Pedro's advices here: <https://gcc.gnu.org/ml/gcc-patches/2014-12/msg01320.html> I adapted the function to print "client connection closed" when it receives a NUL character, or use the "isprint" function to decide how to print the received char. I tested it by running the testcases that were printing the non-printable chars before: gdb.base/gdb-sigterm.exp gdb.threads/non-ldr-exc-1.exp gdb.threads/non-ldr-exc-2.exp gdb.threads/non-ldr-exc-3.exp gdb.threads/non-ldr-exc-4.exp gdb.threads/thread-execl.exp and confirming that they print the right message. I tried a bit to come up with a testcase for this, but failed, and since I did not want to spend too much time on it, I'm sending the patch anyway. Comments are welcome, as usual. gdb/gdbserver/ChangeLog: 2014-12-29 Sergio Durigan Junior <sergiodj@redhat.com> * remote-utils.c: Include ctype.h. (input_interrupt): Explicitly handle the case when the char received is the NUL byte. Improve the printing of non-ASCII characters.

2014-12-29Clean up gdb.trace/entry-values.expYao Qi2-9/+14
This patch is to clean up gdb.trace/entry-values.exp as a preparation of the next patch. It updates the comments to reflect the code. One DIE generated in dwarf assembler is GNU_call_site { {low_pc "$bar_start + $bar_call_foo" addr} {abstract_origin :$foo_label} the DW_AT_low_pc attribute is the return address after the call, so I rename variable bar_call_foo to returned_from_foo. gdb/testsuite: 2014-12-29 Yao Qi <yao@codesourcery.com> * gdb.trace/entry-values.exp: Update comments. Rename variable bar_call_foo to returned_from_foo.
