2014-08-29Make internal_vproblem always workGary Benson3-8/+51
internal_vproblem can be called (via malloc_failure) from almost the first line of captured_main, but it will crash if called before the first call to set_width. This commit makes internal_vproblem work at any time. There are two parts to this. If called before gdb_stderr is set up, internal_vproblem will fall back to printing the message on regular stderr and aborting. If called after gdb_stderr is set up but before filtered printing is set up, internal_vproblem will operate as usual except that it can not query whether to quit and/or dump core so it defaults to doing both. gdb/ChangeLog: * utils.h (filtered_printing_initialized): New declaration. * utils.c (abort_with_message): New function. (internal_vproblem): Use abort_with_message for first level recursive internal problems, and if gdb_stderr is not set up. Protect calls to target_terminal_ours, begin_line and query.

2014-08-28Rewrite {amd64,i386}-pseudo.c to better specify register liveness.Doug Evans3-23/+59
clang was using eax to construct %0 here: asm ("mov %%eax, 0(%0)\n\t" "mov %%ebx, 4(%0)\n\t" "mov %%ecx, 8(%0)\n\t" "mov %%edx, 12(%0)\n\t" "mov %%esi, 16(%0)\n\t" "mov %%edi, 20(%0)\n\t" : /* no output operands */ : "r" (data) : "eax", "ebx", "ecx", "edx", "esi", "edi"); which caused amd64-word.exp (and others similarly) to fail. It's a perfectly legit thing for clang to do given the available data. The patch fixes this by marking the registers as live from the time of the preceding breakpoint. gdb/testsuite/ChangeLog: * gdb.arch/amd64-pseudo.c (main): Rewrite to better specify when eax,etc. are live with values set by gdb and thus the compiler can't use them. * gdb.arch/i386-pseudo.c (main): Ditto.

2014-08-28Convert fatal to perror_with_name in IPA codeGary Benson2-6/+10
This commit converts four calls to fatal into calls to perror_with_name. perror_with_name calls error, which in IPA terminates with exit (1) rather than longjmp, so there is no functional change here. gdb/gdbserver/ChangeLog: * tracepoint.c (gdb_agent_init): Replace fatal with perror_with_name. (initialize_tracepoint): Likewise.
2014-08-28Convert fatal to error in remote_prepareGary Benson2-1/+5
This commit converts a call to fatal in remote_prepare with a call to error. remote_prepare is called precisely once, from main, at a point where jumping to toplevel will call exit (1), so error and fatal are functionally equivalent at this point. Note that remote_prepare calls perror_with_name (which calls error) so callers of remote_prepare must already handle the fact that it may exit via longjmp. gdb/gdbserver/ChangeLog: * remote-utils.c (remote_prepare): Replace fatal with error.
2014-08-28Downgrade fatal to warning in linux_asyncGary Benson2-1/+18
This commit downgrades a fatal error to a warning in linux_async. linux_async is called from two different places in gdbserver: Via target_async from handle_accept_event. The argument is always zero, so the warning will never be printed here. Via start_non_stop from handle_general_set. This prints its own error message to stderr on failure, which will be preceded by the warning if it is emitted. gdb/gdbserver/ChangeLog: * linux-low.c (linux_async): Replace fatal with warning. Tidy up and return. (linux_start_non_stop): Return -1 if linux_async failed.
2014-08-28Convert fatal to gdb_assert in both i386_dr_low_set_addrGary Benson3-5/+10
This commit converts if..fatal checks in both i386_dr_low_set_addr implementations to gdb_asserts. It's not obvious from the context, but the conditional in both cases is changed to match the equivalent conditional in the i386_dr_low_get_addr implementations. Nothing fundamental has changed because DR_FIRSTADDR is zero. This commit also removes a vague comment in Linux i386_dr_low_get_addr. I could have reworded the comment (and replicated it three times for the other identical assertions) but I think the existence of specific functions for the status and control registers makes it fairly obvious what is going on. gdb/gdbserver/ChangeLog: * linux-x86-low.c (i386_dr_low_set_addr): Replace check with gdb_assert. (i386_dr_low_get_addr): Remove vague comment. * win32-i386-low.c (i386_dr_low_set_addr): Replace check with gdb_assert.

2014-08-28arm software watchpoint: return to epilogueYao Qi2-24/+24
Hi, This patch is to handle a software watchpoint case that program returns to caller's epilogue, and it causes the fail in thumb mode, finish^M Run till exit from #0 func () at gdb/testsuite/gdb.base/watchpoint-cond-gone.c:26^M 0x000001f6 in jumper ()^M (gdb) FAIL: gdb.base/watchpoint-cond-gone.exp: Catch the no longer valid watchpoint In the test, jumper calls func, and programs returns from func to jumper's epilogue, IOW, the branch instruction is the last instruction of jumper's function body. jumper: ..... 0x000001f2 <+10>: bl 0x200 [1] <---- indirect call to func 0x000001f6 <+14>: mov sp, r7 [2] <---- start of the epilogue 0x000001f8 <+16>: add sp, #8 0x000001fa <+18>: pop {r7} 0x000001fc <+20>: pop {r0} 0x000001fe <+22>: bx r0 When the inferior returns from func back to jumper, it is expected that an expression of a software watchpoint becomes out-of-scope. GDB validates the expression by checking the corresponding frame, but this check is guarded by gdbarch_in_function_epilogue_p. See breakpoint.c:watchpoint_check. It doesn't work in this case, because program returns from func's epilogue back to jumper's epilogue [2], GDB thinks the program is still within the epilogue, but in fact it goes to a different one. When PC points at [2], the sp-restore instruction is to be executed, so the stack frame isn't destroyed yet and we can still use the frame mechanism reliably. Note that when PC points to the first instruction of restoring SP, it is part of epilogue, but we still return zero. When goes to the next instruction, the backward scan will still match the epilogue sequence correctly. The reason for doing this is to handle the "return-to-epilogue" case. What this patch does is to restrict the epilogue matching that let GDB think the first SP restore instruction isn't part of the epilogue, and fall back to use frame mechanism. We set 'found_stack_adjust' zero before backward scan, and we've done this for arm mode counterpart (arm_in_function_epilogue_p) too. The patch is tested in arm-none-eabi and arm-none-linux-gnueabi with various multilibs. OK to apply? gdb: 2014-08-28 Yao Qi <yao@codesourcery.com> * arm-tdep.c (thumb_in_function_epilogue_p): Don't set found_stack_adjust in forward scan. Remove condition check on found_stack_adjust which is always true. Indent the code.
2014-08-28Remove dwarf_decode_lines argumewant_line_infoYao Qi2-10/+14
Hi, dwarf_decode_lines is called in two functions, dwarf2_build_include_psymtabs and handle_DW_AT_stmt_list, in which, 1 is passed to argument 'want_line_info' and 'want_line_info' is a conditional variable in dwarf_decode_lines. We can simplify it by removing 'want_line_info' and propagating the constant 1 into dwarf_decode_lines. This is what this patch does. This patch also remove one line comment about WANT_LINE_INFO in handle_DW_AT_stmt_list, as handle_DW_AT_stmt_list doesn't have such argument. gdb: 2014-08-28 Yao Qi <yao@codesourcery.com> * dwarf2read.c (dwarf_decode_lines): Update declaration. (handle_DW_AT_stmt_list): Remove comment about WANT_LINE_INFO. (dwarf_decode_lines): Remove argument want_line_info. Remove condition check on want_line_info. Callers update.

2014-08-27Fix terminal state corruption when starting a program from within TUIPatrick Palka7-42/+6
The TUI terminal state becomes corrupted (e.g. key sequences such as Alt_F and Alt_B no longer work) when one attaches to an inferior process (via "run" or "attach") from within TUI. This terminal corruption remains until you switch out of TUI mode. This happens because the terminal state is not properly saved when switching to and out from TUI mode. Although the functions tui_enable() and tui_disable() both call the function target_terminal_save_ours() to save the terminal state, this function is a no-op unless GDB has already attached to an inferior process. This is because only the "native" target has a useful implementation of target_terminal_save_ours() (namely child_terminal_save_ours()) and we only have the "native" target in our target vector if GDB has already attached to an inferior process. So without an inferior process, switching to and from TUI mode does not actually save the terminal state. Therefore when you attach to an inferior process from within TUI mode, the proper terminal state is not restored (after swapping from the inferior's terminal back to the GDB terminal). To fix this we just have to ensure that the terminal state is always being properly saved when switching from and to TUI mode. To achieve this, this patch removes the polymorphic function target_terminal_save_ours() and replaces it with a regular function gdb_save_tty_state() that always saves the terminal state. Tested on x86_64-unknown-linux-gnu by running "make check", no new regressions. gdb/ChangeLog: * target.h (struct target_ops::to_terminal_save_ours): Remove declaration. (target_terminal_save_ours): Remove macro. * target-delegates.c: Regenerate. * inf-child.c (inf_child_target): Don't set the nonexistent field to_terminal_save_ours. * inferior.h (child_terminal_save_ours): Remove declaration. * terminal.h (gdb_save_tty_state): New declaration. * inflow.c (child_terminal_save_ours): Rename to ...

2014-08-27src-release.sh: Convert src-release to a shell scriptWill Newton3-318/+357
This began as an attempt to make a few small changes to src-release but heeding the comments at the top of the file it seemed it might be wise to convert it to a shell script instead which should hopefully be more maintainable. This shell script contains most of the functionality of the Makefile version. It can be run like this: # This will build gdb and compress with bzip2, gzip and xz ./src-release.sh -bgx gdb The functionality that has been removed is building tarballs for insight and gnats, which were broken in the current repository layout and gas+binutils which amounted to basically the same thing as binutils so didn't seem worth keeping. The script always builds a tar file, compression is optional, so no need for specific commands to build tar files rather than compressed tar files. The build of gas releases has been fixed, as has extraction of version numbers which had been broken since the switch to configure.ac files and AC_INIT. I also removed the code for distcleaning the intl sub-directory as it seems like that issue has been fixed. The script is capable of compressing with bzip2, gzip and xz which should cover all formats available on gnu.org. I tested it by producing release tarballs which are substantially identical to the ones produced by the src-release script. ChangeLog: 2014-08-27 Will Newton <will.newton@linaro.org> * src-release.sh: New file. * src-release: Remove file.

2014-08-23Fix m32r-elf sim, default hardware to off.Hans-Peter Nilsson4-12/+13
The situation here is similar to that of the other nearby (previous) sims fixed; it fails at the dv_sockser_install declaration in sim/m32r/tconfig.in. But, as opposed to e.g. frv, this *does* have a definition of UART_INCHAR_ADDR et al. It's somewhat tempting to keep sim-hardware enabled here but, I'm disabling it for the same reasons as for frv. Unsurprisingly (as m32r seems to be the template), the same confusing lines are in sim/m32r/Makefile.in as in sim/frv/Makefile.in at that time, deleted in 73e76d20. Again, commit 73e76d20 (for m32r as well as for frv) attempted to move the non-existing dv-sockser.o use to $(m32r_extra_objs) but missed that AC_SUBST would only affect @m32r_extra_objs@ and not $(m32r_extra_objs) per se so nothing happened. As for frv, I'm removing the $(m32r_extra_objs) too, to avoid confusion. Make check-sim for m32r-elf shows no regressions (5 failures; 100 expected passes) compared to bf3d9781ec049 (before the recent config.in regen, after sim-hardware mostly-enabled) and eed23bb4a1 (before the sim-hardware mostly-enabled; 2013-03-23). sim/m32r: * configure.ac: Default simulator hardware to off again. Remove dead m32r_extra_objs substitution. * configure: Regenerate. * Makefile.in: Remove unused frv_extra_objs.
