2015-07-09[AArch64] Refactor aarch64_make_prologue_cachePierre Langlois2-18/+25
We would previously have to make sure the frame cache was not already created before calling aarch64_make_prologue_cache. This patch makes this function check it so that the caller does not need to do so. gdb/ChangeLog: * aarch64-tdep.c (aarch64_make_prologue_cache): Update comment. New argument this_cache. Return early if this_cache is already set. Set this_cache. (aarch64_prologue_this_id): Update call to aarch64_make_prologue_cache. (aarch64_prologue_prev_register): Likewise. (aarch64_normal_frame_base): Likewise.

2015-07-08Delete program spaces directly when removing inferiorsSimon Marchi7-59/+61
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.

2015-07-08PR18617 - Incorrect expression bytecode generated for narrowing conversionsRobert O'Callahan4-1/+13
The existing code preserves 'from' bits, which is incorrect. E.g. (gdb) maint agent-eval (char)255L Scope: 0x4008d6 Reg mask: 00 0 const16 255 3 ext 64 5 end 'ext 64' should be 'ext 8'; this bytecode evaluates to 255 instead of the correct result of -1.

2015-07-07New proc is_aarch64_targetYao Qi6-4/+23
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.

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.

2015-07-07Adjust gdb.multi tests for aarch64Yao Qi3-2/+41
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.

2015-07-07Set architecture to arm in arm-*.xml filesYao Qi13-0/+33
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.
2015-07-07Native debug arm program by aarch64 GDBYao Qi6-43/+192
This patch is to let aarch64 GDB debug 32-bit arm program natively. In each function for fetching and storing registers, GDB will check gdbarch_bfd_arch_info (gdbarch)->bits_per_word, if it is 32, call the corresponding aarch32 functions in aarch32-linux-nat.c, otherwise fall back to aarch64 code to fetch and store registers. aarch64_linux_read_description has to return the right target description, but we don't have gdbarch available there, so GDB fetches auxv and gets AT_PHENT, in order to determine whether the target is 32-bit or 64-bit.

2015-07-07[arm] Fix regression by Do not skip prologue for asm (.S) filesYao Qi2-0/+7
Patch "Do not skip prologue for asm (.S) files" [1] changes GDB's behaviour on which test gdb.arch/thumb-singlestep.exp depends, so it causes the fail below: (gdb) si^M 37 blx foo^M (gdb) FAIL: gdb.arch/thumb-singlestep.exp: step into foo the test assumes the program will stop at the instruction after "push" but it doesn't. The fix to this fail is to do one more single step. [1] https://sourceware.org/ml/gdb-patches/2015-06/msg00561.html gdb/testsuite: 2015-07-07 Yao Qi <yao.qi@linaro.org> * gdb.arch/thumb-singlestep.exp: Do one more single step.

2015-07-06gdb: Rewrite documentation for layout and focus commands.Andrew Burgess2-16/+36
Changes the documentation for the layout and focus commands. Instead of documenting each layout (or focus) sub-command as a separate command, document a single layout (and focus) command which takes a parameter, then list the possible parameters in a table nested under each command. The documentation for the layout command has been extended little to make it clearer which windows are shown in each layout. gdb/ChangeLog: * doc/gdb.texinfo (TUI): Restructure documentation on TUI layout and focus commands.
2015-07-06Update NEWS post GDB 7.10 branch creation.Joel Brobecker2-1/+9
gdb/ChangeLog: * NEWS: Create a new section for the next release branch. Rename the section of the current branch, now that it has been cut.
2015-07-06Bump version to 7.10.50.DATE-cvs.Joel Brobecker2-1/+6
Now that the GDB 7.10 branch has been created, we can bump the version number. gdb/ChangeLog: GDB 7.10 branch created (66c4b3e8a628a207bc6aafef6af0c4128195f56e): * version.in: Bump version to 7.10.50.DATE-cvs.
2015-07-06Fix problems with finishing a dummy function call on simulators.gdb-7.10-branchpointLuis Machado2-10/+8
This fixes regressions introduced with the original change to not consider permanent breakpoints always inserted: 6ae8866180bf90e9ec76c2dd34c07fd826d11a83 is the first bad commit commit 6ae8866180bf90e9ec76c2dd34c07fd826d11a83 Author: Luis Machado <lgustavo@codesourcery.com> Date: Wed Jun 17 16:50:57 2015 -0300 Fix problems with finishing a dummy function call on simulators. Some checks were mistakenly left out of the original patch, which caused the following failures: -PASS: gdb.base/shlib-call.exp: print mainshr1(1) -PASS: gdb.base/shlib-call.exp: step into mainshr1 +FAIL: gdb.base/shlib-call.exp: print mainshr1(1) +FAIL: gdb.base/shlib-call.exp: step into mainshr1 -PASS: gdb.cp/chained-calls.exp: q(p()) +FAIL: gdb.cp/chained-calls.exp: q(p()) -PASS: gdb.cp/chained-calls.exp: q(p() + r()) +FAIL: gdb.cp/chained-calls.exp: q(p() + r()) -PASS: gdb.cp/chained-calls.exp: g(f(g(f() + f())) + f()) +FAIL: gdb.cp/chained-calls.exp: g(f(g(f() + f())) + f()) -PASS: gdb.cp/chained-calls.exp: *c -PASS: gdb.cp/chained-calls.exp: *c + *c -PASS: gdb.cp/chained-calls.exp: q(*c + *c) +FAIL: gdb.cp/chained-calls.exp: *c +FAIL: gdb.cp/chained-calls.exp: *c + *c +FAIL: gdb.cp/chained-calls.exp: q(*c + *c) -PASS: gdb.cp/classes.exp: calling method for small class +FAIL: gdb.cp/classes.exp: calling method for small class The above is likely caused by GDB not removing the permanent breakpoints from the target, leading to the inferior executing the breakpoint instruction and tripping on a SIGSEGV. gdb/ChangeLog: 2015-07-06 Luis Machado <lgustavo@codesourcery.com> * breakpoint.c (remove_breakpoint_1): Don't handle permanent breakpoints in a special way. (remove_breakpoint): Likewise. (mark_breakpoints_out): Likewise.

2015-07-06gdb/doc: Fix incorrect use of @xref.Andrew Burgess2-1/+5
All uses of @xref must be followed by either '.' or ','. In commit a4ea0946c an incorrect use of @xref was introduced. This commit adds a comma after the use of @xref. gdb/ChangeLog: * doc/gdb.texinfo (TUI): Add comma after @xref.
2015-07-06gdb/tui: Don't cast between window types.Andrew Burgess2-2/+6
Instead of casting between structure types to get the 'tui_gen_win_info' info from a 'tui_win_info' access the generic member variable. This is inline with what is done throughout the rest of the tui code. gdb/ChangeLog: * tui/tui-win.c (tui_set_focus): Use structure member 'generic' instead of casting the structure type.
2015-07-06search_struct_field: remove OFFSET parameterSimon Marchi2-12/+18
I was trying to understand what the OFFSET parameter was for, and realized it was set to 0 in every call to search_struct_field. I assume that it was used at some point, but some subsequent changes made it useless. gdb/ChangeLog: * valops.c (search_struct_field): Remove OFFSET parameter. (value_cast_structs): Adjust calls to search_struct_field. (value_struct_elt): Same. (find_overload_match): Same.
2015-07-06Cleanup value_fetch_lazy's comment and return valueSimon Marchi3-13/+12
The comment for value_fetch_lazy seems outdated. It says that it's only called from the value_contents and value_contents_all (macros!), which is not true. Also, the return value seems useless now, despite what the comment says. gdb/ChangeLog: * value.c (value_fetch_lazy): Update comment, change return value to void. * value.h (value_fetch_lazy): Change return value to void.
