2015-01-07Don't propagate our current terminal state to the inferiorPatrick Palka4-1/+27
Currently when we start an inferior we have the inferior inherit our terminal state. Under TUI, our terminal is highly modified by ncurses and readline. So when starting an inferior under TUI, the inferior will have a highly modified terminal state which will interfere with standard I/O. For example, $ gdb gdb (gdb) break main (gdb) run (gdb) print puts ("a\nb") a b $1 = 4 (gdb) [enter TUI mode] (gdb) run (gdb) [exit TUI mode] (gdb) print puts ("a\nb") a b $2 = 4 (gdb) print puts ("a\r\nb\r") a b $3 = 6 As you can see, when we start the inferior under the regular interface, puts() prints the text properly. But when we start the inferior under TUI, puts() does not print the text properly. This is because when we start the inferior under TUI it inherits our current terminal state which has been modified by ncurses to, among other things, require an explicit \r\n to print a new line. As a result the inferior performs standard I/O in an unexpected way. Because of this discrepancy, it doesn't seem like a good idea to have the inferior inherit our _current_ terminal state for it may have been modified by readline and/or ncurses. Instead, we should have the inferior inherit a pristine snapshot of our terminal state taken before readline or ncurses have had a chance to alter it. This enables the inferior to run in a more accurate way, more closely mimicking the program's behavior had it run standalone. And it fixes the above mentioned issue. Tested on x86_64-unknown-linux-gnu. gdb/ChangeLog: * terminal.h (set_initial_gdb_ttystate): Declare. * inflow.c (initial_gdb_ttystate): New static variable. (set_initial_gdb_ttystate): New setter. (child_terminal_init_with_pgrp): Copy initial_gdb_ttystate instead of our current terminal state. * top.c (gdb_init): Call set_initial_gdb_ttystate.

2015-01-07arm: fix extension feature disablingJan Beulich2-15/+33
Using e.g. .arch_extension simd .arch_extension nocrypto so far results in SIMD support getting disabled, which I can't see being the purpose of the "no"-prefixed variants of architecture extension specifications. Of course it is questionable whether the current, counter intuitive behavior needs to be retained, and the new behavior perhaps be made work through e.g. a newly recognized "no-" prefix. gas/ 2015-01-07 Jan Beulich <jbeulich@suse.com> * gas/config/tc-arm.c (struct arm_option_extension_value_table): Split field "value" into fields "merge_value" and "clear_value".

2015-01-06gdb/guile: Do not error when trying to create empty array.Joel Brobecker2-1/+6
This fixes a similar error as in the Python support code where trying to create an empty array. In guile/scm-type.c::tyscm_array_1, the funtion raises an exception if N2 < N1: if (n2 < n1) { gdbscm_out_of_range_error (func_name, SCM_ARG3, But it should be doing so if N2 == N1 - 1, since that would simply be an empty array, not an array with a negative length. gdb/ChangeLog: * guile/scm-type.c (tyscm_array_1): Do not raise out-of-range error if N2 is equal to N1 - 1.
