Andrew Burgess	6dce28e413	gdb: Convert TUI windows names to lower case. This commit converts the window names for the TUI windows to lower case. The windows names are already lower case in the documentation, and are shown as lower case in some of the command completion results. Given that all the commands that take a window name currently accept upper or lower case, this commit just changes the window names to lower case in the remaining places they are displayed by gdb. gdb/ChangeLog: * tui/tui-data.h (SRC_NAME): Convert to lower case. (CMD_NAME): Likewise. (DATA_NAME): Likewise. (DISASSEM_NAME): Likewise. * tui/tui-win.c (tui_set_focus): Window names are now lower case. (tui_set_win_height): Likewise.

Han Shen	61163dfaae	Drop 'missing mapping symbols' warning for arm and aarch64. The psABI (AAELF) says this about mapping symbols: 4.6.5.1 Section-relative mapping symbols Mapping symbols defined in a section define a sequence of half-open address intervals that cover the address range of the section. Each interval starts at the address defined by the mapping symbol, and continues up to, but not including, the address defined by the next (in address order) mapping symbol or the end of the section. A section must have a mapping symbol defined at the beginning of the section; however, if the section contains only data then the mapping symbol may be omitted. That makes it pretty clear that, in the absence of a mapping symbol, the entire section can be treated as data. gold/ChangeLog: * aarch64.cc (AArch64_relobj::scan_errata): Drop missing symbol warning. * arm.cc (Arm_relobj::scan_section_for_cortex_a8_erratum): Drop missing symbol warning.	11 years ago

Note that it does not add support for testing fast tracepoint as it isn't supported.

Pierre Langlois	02a2a705aa	[AArch64] Teach stub unwinder to terminate gracefully The stub unwinder is used on AArch64 if the target's memory is not readable at the current PC. For example, the user could try to call at an invalid address such as 0x0, as covered in the gdb.base/signull.exp test case. Many GDB ports use a similar unwinder to handle this case too. If we purposely kill the inferior before examining the trace then we get the following issue: ~~~ ... (gdb) trace f Tracepoint 3 at 0x7fb7fc28c0 (gdb) tstart (gdb) continue ... (gdb) tstop (gdb) tsave /tmp/trace (gdb) kill ... (gdb) target tfile /tmp/trace ... (gdb) tfind Register 31 is not available. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Found trace frame 0, tracepoint 3 #-1 0x0000007fb7fc28c0 in f () ... ^^^ ~~~ This patch teaches the stub unwinder to report to the core frame code with UNWIND_UNAVAILABLE when either the stack pointer of the return address are unavailable to read from the target. gdb/ChangeLog: * aarch64-tdep.c (aarch64_make_stub_cache): Set available_p and swallow NOT_AVAILABLE_ERROR. (aarch64_stub_this_id): Call frame_id_build_unavailable_stack if available_p is not set. (aarch64_stub_frame_unwind_stop_reason): New function. (aarch64_stub_unwind): Install it.	11 years ago
Pierre Langlois	7dfa3edc03	[AArch64] Teach prologue unwinder to terminate gracefully Without debugging information, we have the following issue when examining a trace buffer: ~~~ ... (gdb) trace f Tracepoint 3 at 0x7fb7fc28c0 (gdb) tstart (gdb) continue ... (gdb) tstop (gdb) tfind start Register 31 is not available. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Found trace frame 0, tracepoint 3 #-1 0x0000007fb7fc28c0 in f () ... ^^^ ~~~ The reason for this is that the target's stack pointer is unavailable when examining the trace buffer. What we are seeing is due to the 'tfind' command creating a sentinel frame and unwinding it. If an exception is thrown, we are left with the sentinel frame being displayed at level #-1. The exception is thrown when the prologue unwinder tries to read the stack pointer to construct an ID for the frame. This patch fixes this by making the prologue unwinder catch NOT_AVAILABLE_ERROR exceptions when either registers or memory is unreadable and report back to the frame core code with UNWIND_UNAVAILABLE. gdb/ChangeLog: * aarch64-tdep.c (aarch64_prologue_cache) <available_p>: New field.

Pierre Langlois	db63414322	[AArch64] Only access inferior registers when creating a frame cache This patch moves the address of the start of a function (func) and the address from which it was called (prev_pc) into aarch64_prologue_cache. The idea is to keep accesses to the inferior's registers into aarch64_make_prologue_cache and aarch64_make_stub_cache. gdb/ChangeLog: * aarch64-tdep.c (aarch64_prologue_cache) <func, prev_pc>: New fields.

Simon Marchi	7a41607e01	Delete program spaces directly when removing inferiors When deleting an inferior, delete the associated program space as well if it becomes unused. This replaces the "pruning" approach, with which you could forget to call prune_program_spaces (as seen, with the -remove-inferior command, see [1]). This allows to remove the prune_program_spaces function. At the same time, I was able to clean up the delete_inferior* family: - delete_inferior is unused - delete_inferior_silent is only used in monitor_close, but is replaced with discard_all_inferiors [2], so it becomes unused - All remaining calls to delete_inferior_1 are with silent=1, so the parameter is removed - delete_inferior_1 is renamed to delete_inferior I renamed pspace_empty_p to program_space_empty_p. I prefer if the "exported" functions have a more explicit and standard name. Tested on Ubuntu 14.10.

Yao Qi	4931af25b8	New proc is_aarch64_target Some tests expect the the target is aarch64, but checking target triplet is not accurate, because target triplet can be aarch64 but the program is in arm (or aarch32) state.

Yao Qi	9fcf688e80	New proc is_aarch32_target GDB tests running on arm target should be also run on aarch32 (32-bit mode on aarch64). There should be no difference. It is not precise to check target triplet to decide which tests should be run, because if I compiler all the test binary in 32-bit (arm program), but target triplet is still aarch64, so that these arm specific tests are skipped. This patch is to add a new proc is_aarch32_target which return true if target triplet is arm or the test binary is compiled for arm. gdb/testsuite: 2015-07-07 Yao Qi <yao.qi@linaro.org> * lib/gdb.exp (is_aarch32_target): New proc. * gdb.arch/arm-bl-branch-dest.exp: Check is_aarch32_target instead of "istarget "arm--"". gdb.arch/arm-disp-step.exp: Likewise. * gdb.arch/thumb-bx-pc.exp: Likewise. * gdb.arch/thumb-prologue.exp: Likewise. * gdb.arch/thumb-singlestep.exp: Likewise. * gdb.base/disp-step-syscall.exp: Likewise. * gdb.base/float.exp: Likewise.	11 years ago

Yao Qi	71be1fdc36	Adjust gdb.multi tests for aarch64 Multi-arch related tests under gdb.multi are to compile programs with the same compiler but different compiler options (-m64 vs -m32). However, different compilers are needed to compile both aarch64 program and arm (aarch32) program. This patch is to adjust these test cases to compile programs in different modes with different compiler. When we use gcc for arm-linux target, its file name can be different, arm-linux-gnueabihf-gcc, arm-linux-gnueabi-gcc, or arm-none-linux-gnueabi-gcc, so I add a variable ARM_CC_FOR_TARGET, so that user can set the name of gcc for arm-linux target on aarch64, like: $ make check RUNTESTFLAGS='ARM_CC_FOR_TARGET=arm-linux-gnueabihf-gcc multi-arch.exp' gdb/testsuite: 2015-07-07 Yao Qi <yao.qi@linaro.org> * gdb.multi/multi-arch-exec.exp: Set march1 and march2 to "" if target is aarch64.

Yao Qi	82c40d4b1d	Set architecture to arm in arm-.xml files This patch is to add the following line to various arm target description xml files, <architecture>arm</architecture> in order to fix problems I've seen on aarch64 multi-arch debugging, detach^M Detaching from program: build-gdb/gdb/testsuite/gdb.base/attach, process 17145^M (gdb) PASS: gdb.base/attach.exp: attach1 detach file^M No executable file now.^M Architecture of file not recognized.^M (gdb) FAIL: gdb.base/attach.exp: attach1, purging symbols after detach Without this patch, struct target_desc tdesc_* are not initialised properly, that is, fields arch and osabi in 'struct target_desc' are not set properly. This doesn't cause any problems on single arch debugging, because arch-utils.c:gdbarch_info_fill will guess correctly. However, in multi-arch debugging, gdbarch_info_fill gets the aarch64 arch, but the target description is for arm (because the current inferior is 32-bit arm). It is a surprise to me we didn't set architecture to "arm" before in .xml files, and I didn't find out why didn't do so. AFAICS, gdb/features/arm-with-iwmmxt.xml was added firstly (in patch https://sourceware.org/ml/gdb-patches/2007-01/msg00593.html) which had <architecture>iwmmxt</architecture>, however, afterwards, architecture isn't set anymore in features/arm-.xml files (in patches https://sourceware.org/ml/gdb-patches/2009-07/msg00689.html and https://sourceware.org/ml/gdb-patches/2010-08/msg00225.html). gdb: 2015-07-07 Yao Qi <yao.qi@linaro.org> * features/arm-with-m-fpa-layout.xml: Set architecture to arm. * features/arm-with-m-fpa-layout.c: Regenerated. * features/arm-with-m-vfp-d16.xml: Likewise. * features/arm-with-m-vfp-d16.c: Regenerated. * features/arm-with-m.xml: Likewise. * features/arm-with-m.c: Regenerated. * features/arm-with-neon.xml: Likewise. * features/arm-with-neon.c: Regenerated. * features/arm-with-vfpv2.xml: Likewise. * features/arm-with-vfpv2.c: Regenerated. * features/arm-with-vfpv3.xml: Likewise. * features/arm-with-vfpv3.c: Regenerated.	11 years ago
