2016-06-07PowerPC VLEAlan Modra18-3720/+3866
VLE is an encoding, not a particular processor architecture, so it isn't really proper to select insns based on PPC_OPCODE_VLE. For example {"evaddw", VX (4, 512), VX_MASK, PPCSPE|PPCVLE, PPCNONE, {RS, RA, RB}}, {"vaddubs", VX (4, 512), VX_MASK, PPCVEC|PPCVLE, PPCNONE, {VD, VA, VB}}, shows two insns that have the same encoding, both available with VLE. Enabling both with VLE means we can't disassemble the second variant even if -Maltivec is given rather than -Mspe. Also, we don't check user assembly against the processor type as well as we could. Another problem is that when using the VLE encoding, insns from the main ppc opcode table are not available, except those using opcode 4 and 31. Correcting this revealed two errors in the ld testsuite, use of "nop" and "rfmci" when -mvle. This patch fixes those problems in the opcode table, and removes PPCNONE. I find a plain 0 distracts less from other values. In addition, I've implemented code to recognize some machine values from the apuinfo note present in ppc32 objects. It's not a complete disambiguation since we're lacking info to detect newer chips, but what we have should help with disassembly. include/ * elf/ppc.h (APUINFO_SECTION_NAME, APUINFO_LABEL, PPC_APUINFO_ISEL, PPC_APUINFO_PMR, PPC_APUINFO_RFMCI, PPC_APUINFO_CACHELCK, PPC_APUINFO_SPE, PPC_APUINFO_EFS, PPC_APUINFO_BRLOCK, PPC_APUINFO_VLE: Define. opcodes/ * ppc-dis.c (ppc_opts): Delete extraneous parentheses.

2016-06-06Add method/format information to =record-startedSimon Marchi13-11/+94
Eclipse CDT now supports enabling execution recording using two methods (full and btrace) and both formats for btrace (bts and pt). In the event that recording is enabled behind the back of the GUI (by the user on the command line, or a script), we need to know which method/format are being used, so it can be correctly reflected in the interface. This patch adds this information to the =record-started async record. Before: =record-started,thread-group="i1" After: =record-started,thread-group="i1",method="btrace",format="bts" =record-started,thread-group="i1",method="btrace",format="pt" =record-started,thread-group="i1",method="full" The "format" field is only present when the current method supports multiple formats (only the btrace method as of now). gdb/ChangeLog: * NEWS: Mention the new fields in =record-started. * common/btrace-common.h (btrace_format_short_string): New function declaration. * common/btrace-common.c (btrace_format_short_string): New function. * mi/mi-interp.c (mi_record_changed): Output method and format fields in the =record-started record. * record-btrace.c (record_btrace_open): Adapt record_changed notification. * record-full.c (record_full_open): Likewise. * record.c (cmd_record_stop): Likewise. gdb/doc/ChangeLog: * gdb.texinfo (GDB/MI Async Records): Document method and format fields in =record-started. * observer.texi (record_changed): Add method and format parameters. gdb/testsuite/ChangeLog: * gdb.mi/mi-record-changed.exp: Adjust =record-started output matching.
2016-06-06Support x86-64 TLS code sequences without PLTH.J. Lu48-112/+2789
We can generate x86-64 TLS code sequences for general and local dynamic models without PLT, which uses indirect call via GOT: call *__tls_get_addr@GOTPCREL(%rip) instead of direct call: call __tls_get_addr[@PLT] Since direct call is 4-byte long and indirect call, is 5-byte long, the extra one byte must be handled properly. For general dynamic model, one 0x66 prefix before call instruction is removed to make room for indirect call. For local dynamic model, we simply use 5-byte indirect call. TLS linker optimization is updated to recognize new instruction patterns. For local dynamic model to local exec model transition, we generate 4 0x66 prefixes, instead of 3, before mov instruction in 64-bit and generate a 5-byte nop, instead of 4-byte, before mov instruction in 32-bit. Since linker may convert call *__tls_get_addr@GOTPCREL(%rip) to addr32 call __tls_get_addr when producing static executable, both patterns are recognized. bfd/ * elf64-x86-64.c (elf_x86_64_link_hash_entry): Add tls_get_addr.

This reverts the pr16467 change, which was incorrect due to faulty analysis of the pr16467 testcase. The failure was not due to a mismatch in symbol type (ifunc/non-ifunc) but due to a symbol loop being set up.

... and fix Ctrl-C races. The current remote-fileio.c SIGINT/EINTR code can lose Ctrl-C -- there's a period where SIG_IGN is installed as signal handler, for example. Since: - remote.c no longer installs a custom SIGINT handler; - The current remote-fileio.c SIGINT handler is basically the same as the default SIGINT handler (event-top.c:handle_sigint), in principle, except that instead of setting the quit flag, it sets a separate flag. I think we should be able to completely remove the remote-fileio.c SIGINT handler, and centralize on the quit flag, thus fixing the Ctrl-C race. gdb/ChangeLog: yyyy-mm-dd Pedro Alves <palves@redhat.com> * remote-fileio.c (remote_fio_ctrl_c_flag, remote_fio_sa) (remote_fio_osa) (remote_fio_ofunc, remote_fileio_sig_init, remote_fileio_sig_set) (remote_fileio_sig_exit, remote_fileio_ctrl_c_signal_handler): Delete.

Patch 7eb895307f53 Skip unwritable frames in command "finish" skips non-writable frames in addition to tailcall frames. If skip_tailcall_frames already returns NULL, skip_unwritable_frames will be called with a NULL frame and crash in get_frame_arch. This is caught by gdb.btrace/tailcall-only.exp. Further, if we ever end up with a mixture of tailcall and non-writable frames, we may not skip all of them, as intended. Loop over skip_tailcall_frames and skip_unwritable_frames as long as at least one of them makes progress. gdb/ * infcmd.c (skip_finish_frames): New. (finish_command): Call skip_finish_frames.
2016-06-01Wake up interruptible_select in remote_fileio ctrl-c handlerYao Qi2-0/+8
As reported in PR 19998, after type ctrl-c, GDB hang there and does not send interrupt. It causes a fail in gdb.base/interrupt.exp. All targets support remote fileio should be affected. When we type ctrc-c, SIGINT is handled by remote_fileio_sig_set, as shown below, #0 remote_fileio_sig_set (sigint_func=0x4495d0 <remote_fileio_ctrl_c_signal_handler(int)>) at /home/yao/SourceCode/gnu/gdb/git/gdb/remote-fileio.c:325 #1 0x00000000004495de in remote_fileio_ctrl_c_signal_handler (signo=<optimised out>) at /home/yao/SourceCode/gnu/gdb/git/gdb/remote-fileio.c:349 #2 <signal handler called> #3 0x00007ffff647ed83 in __select_nocancel () at ../sysdeps/unix/syscall-template.S:81 #4 0x00000000005530ce in interruptible_select (n=10, readfds=readfds@entry=0x7fffffffd730, writefds=writefds@entry=0x0, exceptfds=exceptfds@entry=0x0, timeout=timeout@entry=0x0) at /home/yao/SourceCode/gnu/gdb/git/gdb/event-top.c:1017 #5 0x000000000061ab20 in stdio_file_read (file=<optimised out>, buf=0x12d02e0 "\n\022-\001", length_buf=16383) at /home/yao/SourceCode/gnu/gdb/git/gdb/ui-file.c:577 #6 0x000000000044a4dc in remote_fileio_func_read (buf=0x12c0360 "") at /home/yao/SourceCode/gnu/gdb/git/gdb/remote-fileio.c:583 #7 0x0000000000449598 in do_remote_fileio_request (uiout=<optimised out>, buf_arg=buf_arg@entry=0x12c0340) at /home/yao/SourceCode/gnu/gdb/git/gdb/remote-fileio.c:1179 we don't set quit_serial_event, do { res = gdb_select (n, readfds, writefds, exceptfds, timeout); } while (res == -1 && errno == EINTR); if (res == 1 && FD_ISSET (fd, readfds)) { errno = EINTR; return -1; } return res; we can't go out of the loop above, and that is why GDB can't send interrupt. Recently, we stop throwing exception from SIGINT handler (remote_fileio_ctrl_c_signal_handler) https://sourceware.org/ml/gdb-patches/2016-03/msg00372.html, which is correct, because gdb_select is interruptible. However, in the same patch series, we add interruptible_select later as a wrapper to gdb_select, https://sourceware.org/ml/gdb-patches/2016-03/msg00375.html and it is not interruptible (because of the loop in it) unless select/poll-able file descriptors are marked. This fix in this patch is to call quit_serial_event_set, so that we can go out of the loop above, return -1 and set errno to EINTR. 2016-06-01 Yao Qi <yao.qi@linaro.org> PR remote/19998 * remote-fileio.c (remote_fileio_ctrl_c_signal_handler): Call quit_serial_event_set.

2016-05-31[PR gdb/19893] Fix handling of synthetic C++ referencesMartin Galvan12-93/+851
https://sourceware.org/bugzilla/show_bug.cgi?id=19893 I've traced the main source of the problem to pieced_value_funcs.coerce_ref not being implemented. Since gdb always assumes references are implemented as pointers, this causes it to think that it's dealing with a NULL pointer, thus breaking any operations involving synthetic references. What I did here was implementing pieced_value_funcs.coerce_ref using some of the synthetic pointer handling code from indirect_pieced_value, as Pedro suggested. I also made a few adjustments to the reference printing code so that it correctly shows either the address of the referenced value or (if it's non-addressable) the "<synthetic pointer>" string. I also wrote some unit tests based on Dwarf::assemble; these took a while to make because in most cases I needed a synthetic reference to a physical variable. Additionally, I started working on a unit test for classes that have a vtable, but ran into a few issues so that'll probably go in a future patch. One thing that should definitely be fixed is that proc function_range (called for MACRO_AT_func) will always try to compile/link using gcc with the default options instead of g++, thus breaking C++ compilations that require e.g. libstdc++. gdb/ChangeLog: * dwarf2loc.c (coerce_pieced_ref, indirect_synthetic_pointer, fetch_const_value_from_synthetic_pointer): New functions.
