2017-01-10Change return type of ui_out redirect to voidSimon Marchi11-32/+34

2017-01-10Update help of the "frame" commandSimon Marchi2-3/+5
The help message of the "frame" command states that nothing is printed if the command is executed from the command file or user-defined command. My testing leads me to think that this is not true (at least today). (gdb) bt #0 bar (n=17) at test.c:9 #1 0x00000000004006e0 in foo (v=17) at test.c:13 #2 0x00000000004006f0 in main () at test.c:21 (gdb) frame #0 bar (n=17) at test.c:9 9 baz(n); (gdb) define foo Type commands for definition of "foo". End with a line saying just "end". >frame 1 >end (gdb) foo #1 0x00000000004006e0 in foo (v=17) at test.c:13 13 bar(v); This patch simply removes that bit from the help message. I didn't find anything corresponding to this in the documentation that needs to be fixed. The behavior change corresponding to this documentation change was done in commit b00771232fab861fb31e42dfd5f6643ba1b43cc9. gdb/ChangeLog: * stack.c (_initialize_stack): Update "frame" command help message.

2017-01-10[ARC] Add new linker emulation for npsGraham Markall8-2/+205
The arc700 nps variant uses some specific named sections to facilitate its CMEM based instructions, which operate on memory regions fixed at specific addresses. This commit adds the arclinux_nps emulation, which is based on the arclinux emulation. The new emulation uses the OTHER_SECTIONS variable in the emulation parameters script to provide symbols mapping to various locations in the CMEM space on nps. The accompanying test ensures that all symbols are provided at the correct address in the linker script. ld/ChangeLog: * Makefile.am: Add earclinux_nps.c target and add to ALL_EMULATION_SOURCES. * Makefile.in: Likewise, regenerated. * configure.tgt: Add arclinux_nps as an extra emulation for arc*-*-elf* and arc*-*-linux*. * emulparams/arc-nps.sh: New file. * emulparams/arclinux_nps.sh: New file. * testsuite/ld-arc/arclinux-nps.d, * testsuite/ld-arc/arclinux-nps.s: New test.

2017-01-10[GOLD] Fix tests for powerpc64Alan Modra4-10/+54
PowerPC64 defines .TOC. rather than _GLOBAL_OFFSET_TABLE_, and what's more, doesn't define it at all unless referenced. For ELFv1 ABI the symbol isn't normally referenced, so modify the test to accept .TOC. as a variant of _GLOBAL_OFFSET_TABLE_ and 0 or 1 occurrences. copy_test_relro as written doesn't need copy relocs on PowerPC64. PowerPC64 is always PIC. So, modify copy_test_relro to test that the existing vars are in fact read-only directly by deliberately causing a sigsegv, and add another couple of vars that do cause copy relocs even when PIC. * testsuite/ver_test_8.sh: Accept .TOC. in lieu of _GLOBAL_OFFSET_TABLE_. Allow zero count. * testsuite/copy_test_relro_1.cc (c, q): New vars. * testsuite/copy_test_relro.cc: Rewrite to test read-only status of variables directly. Reference new vars in read-only data.
2017-01-10[GOLD] Add --secure-plt option for ppc32Alan Modra3-0/+48
Added just to accept, and ignore. gcc since 2015-10-21, when configured with --enable-secureplt passes this option to the linker. As powerpc gold cannot link --bss-plt code successfully, gold needs to accept the option or the gcc specs file needs to be changed. The patch also make gold detect --bss-plt code and error out rather than producing a binary that crashes. * options.h: Add --secure-plt option. * powerpc.cc (Target_powerpc::Scan::local): Detect and error on -fPIC -mbss-plt code. (Target_powerpc::Scan::global): Likewise.

2017-01-09Fix inferior memory reading in GDBServer for arm/aarch32Antoine Tremblay3-4/+12
Before this patch, some functions would read the inferior memory with (*the_target)->read_memory, which returns the raw memory, rather than the shadowed memory. This is wrong since these functions do not expect to read a breakpoint instruction and can lead to invalid behavior. Use of raw memory in get_next_pcs_read_memory_unsigned_integer for example could lead to get_next_pc returning an invalid pc. Here's how this would happen: In non-stop: the user issues: thread 1 step& thread 2 step& thread 3 step& In a similar way as non-stop-fair-events.exp (threads are looping). GDBServer: linux_resume is called GDBServer has pending events, threads are not resumed and single-step breakpoint for thread 1 not installed. linux_wait_1 is called with a pending event on thread 2 at pc A GDBServer handles the event and calls proceed_all_lwps This calls proceed_one_lwp and installs single-step breakpoints on all the threads that need one. Now since thread 1 needs to install a single-step breakpoint and is at pc B (different than thread 2), a step-over is not initiated and get_next_pc is called to figure out the next instruction from pc B. However it may just be that thread 3 as a single step breakpoint at pc B. And thus get_next_pc fails. This situation is tested with non-stop-fair-events.exp. In other words, single-step breakpoints are installed in proceed_one_lwp for each thread. GDBserver proceeds two threads for resume_step, as requested by GDB, and the thread proceeded later may see the single-step breakpoints installed for the thread proceeded just now. Tested on gdbserver-native/-m{thumb,arm} no regressions. gdb/gdbserver/ChangeLog: * linux-aarch32-low.c (arm_breakpoint_kind_from_pc): Use target_read_memory. * linux-arm-low.c (get_next_pcs_read_memory_unsigned_integer): Likewise. (get_next_pcs_syscall_next_pc): Likewise.
2017-01-09RISC-V/GAS: Support more relocs against constant addressesAndrew Waterman2-3/+8
Previously, some pseudoinstructions like "call" only accepted symbolic addresses and rejected constant addresses with an esoteric internal error. This patch enables them by deferring application of constant relocations to md_apply_fix, rather than eagerly applying them during instruction assembly. gas/ChangeLog 2017-01-09 Andrew Waterman <andrew@sifive.com> * config/tc-riscv.c (append_insn): Don't eagerly apply relocations against constants. (md_apply_fix): Mark relocations against constants as "done."

2017-01-09Remove some custom sections from RISC-V's default linker scriptsPalmer Dabbelt2-12/+7
This was added so compressed loads could have smaller offsets for accessing the data section, but the result was that writable sections ended up in INITIAL_READONLY_SECTIONS. This is a bad idea. The fix is to just remove this micro-optimization.

2017-01-08[D] Fix crash when debug expression enabled.Iain Buclaw4-6/+51
While casting works as expected with expression debugging turned off, this seems to be an indication that the D language parser function is doing something wrong in the building of the expression.
