2014-07-23rewrite make-target-delegates matching codeTom Tromey3-55/+83
This patch rewrites the make-target-delegates matching code a little bit. The result is functionally the same (the output has some small whitespace differences), but the new code is more forgiving regarding the formatting of target.h. In particular now there's no need to ensure that the return type and the method name appear on the same line. 2014-07-23 Tom Tromey <tromey@redhat.com> * make-target-delegates ($ARGS_PART): Match trailing close paren. ($INTRO_PART): Don't match whitespace. ($METHOD_TRAILER): Move earlier. Remove trailing semicolon and argument matching. ($METHOD): Add $METHOD_TRAILER. (trim): Rewrite. (scan_target_h): New sub. Change main loop not to collect state. * target-delegates.c: Rebuild.

2014-07-22Remove setting value address for reference entry value target data value.Jan Kratochvil2-9/+5
I cannot reproduce any wrong case having the code removed. I just do not find it correct to have it disabled. But at the same time I do like much / I do not find correct the code myself. It is a bit problematic to have struct value describing a memory content which is no longer present there. What happens there: ------------------------------------------------------------------------------ volatile int vv; static __attribute__((noinline)) int bar (int &ref) { ref = 20; vv++; /* break-here */ return ref; } int main (void) { int var = 10; return bar (var); } ------------------------------------------------------------------------------ <4><c7>: Abbrev Number: 13 (DW_TAG_GNU_call_site_parameter) <c8> DW_AT_location : 1 byte block: 55 (DW_OP_reg5 (rdi)) <ca> DW_AT_GNU_call_site_value: 2 byte block: 91 74 (DW_OP_fbreg: -12) <cd> DW_AT_GNU_call_site_data_value: 1 byte block: 3a (DW_OP_lit10) ------------------------------------------------------------------------------ gdb -ex 'b value_addr' -ex r --args ../gdb ./1 -ex 'watch vv' -ex r -ex 'p &ref@entry' -> 6 return ref; bar (ref=@0x7fffffffd944: 20, ref@entry=@0x7fffffffd944: 10) at 1.C:25 ------------------------------------------------------------------------------ At /* break-here */ struct value variable 'ref' is TYPE_CODE_REF. With FSF GDB HEAD: (gdb) x/gx arg1.contents 0x6004000a4ad0: 0x00007fffffffd944 (gdb) p ((struct value *)arg1.location.computed.closure).lval $1 = lval_memory (gdb) p/x ((struct value *)arg1.location.computed.closure).location.address $3 = 0x7fffffffd944 With your #if0-ed code: (gdb) x/gx arg1.contents 0x6004000a4ad0: 0x00007fffffffd944 (gdb) p ((struct value *)arg1.location.computed.closure).lval $8 = not_lval (gdb) p/x ((struct value *)arg1.location.computed.closure).location.address $9 = 0x0 I do not see how to access ((struct value *)arg1.location.computed.closure).location.address from GDB CLI. Trying (gdb) p &ref@entry will invoke value_addr()'s: if (TYPE_CODE (type) == TYPE_CODE_REF) /* Copy the value, but change the type from (T&) to (T*). We keep the same location information, which is efficient, and allows &(&X) to get the location containing the reference. */ and therefore the address gets fetched already from arg1.contents and not from ((struct value *)arg1.location.computed.closure).location.address . And for any other type than TYPE_CODE_REF this code you removed does not get executed at all. This DW_AT_GNU_call_site_data_value DWARF was meant primarily for Fortran but with -O0 entry values do not get produced and with -Og and higher Fortran always optimizes out the passing by reference. If you do not like the removed code there I am OK with removing it as I do not know how to make it's use reproducible for user anyway. In the worst case - if there really is some way how to exploit it - one should just get Attempt to take address of value not located in memory. instead of some wrong value and it may be easy to fix then. gdb/ 2014-07-22 Jan Kratochvil <jan.kratochvil@redhat.com> * dwarf2loc.c (value_of_dwarf_reg_entry): Remove setting value address for reference entry value target data value.

Prior to version MicroBlaze v8.10.a,EDK 13.1, XMD's gdbserver stub returned 57 registers in response to GDB's G request. Starting with version MicroBlaze v8.10.a, EDK 13.1, XMD added the slr and shr register, for a count of 59 registers. This patch adds these registers to the expected G response.

2014-07-18fix calls to find_target_beneathTom Tromey3-3/+11
A long time ago Pedro pointed out that there are some calls to find_target_beneath that pass in an explicit target_ops; but which should instead use the ops provided to the method in question. See: https://sourceware.org/ml/gdb-patches/2014-01/msg00429.html This patch is just a minor cleanup to fix all such calls. There were only three. 2014-07-18 Tom Tromey <tromey@redhat.com> * spu-multiarch.c (spu_region_ok_for_hw_watchpoint): Pass "self" to find_target_beneath. * ravenscar-thread.c (ravenscar_prepare_to_store): Pass "ops" to find_target_beneath.

2014-07-18fix PR gdb/17130Tom Tromey4-2/+34
This fixes PR gdb/17130. The bug is that some code in utils.c was not updated during the target delegation change: if (job_control /* If there is no terminal switching for this target, then we can't possibly get screwed by the lack of job control. */ || current_target.to_terminal_ours == NULL) fatal ("Quit"); else fatal ("Quit (expect signal SIGINT when the program is resumed)"); After the delegation change, to_terminal_ours will never be NULL. I think this bug can be seen before the target delegation change by enabling target debugging -- this would also cause to_terminal_ours to be non-NULL. The fix is to introduce a new target_supports_terminal_ours function, that properly checks the target stack. This is not perhaps ideal, but I think is a reasonable-enough approach, and in keeping with some other existing code of the same form. This patch also fixes a similar bug in target_supports_delete_record. 2014-07-18 Tom Tromey <tromey@redhat.com> PR gdb/17130: * utils.c (quit): Use target_supports_terminal_ours. * target.h (target_supports_terminal_ours): Declare. * target.c (target_supports_delete_record): Don't check to_delete_record against NULL.

2014-07-18clean up some target delegation casesTom Tromey8-97/+50
This patch cleans up some minor inconsistencies in target delegation. It's primary purpose is to avoid confusion in the code. A few spots were checking the "beneath" target; however this can only be NULL for the dummy target, so such tests are not needed. Some other spots were iterating over the beneath targets, looking for a method implementation. This is not needed for methods handled by make-target-delegates, as there is always an implementation. 2014-07-18 Tom Tromey <tromey@redhat.com> PR gdb/17130: * spu-multiarch.c (spu_region_ok_for_hw_watchpoint) (spu_fetch_registers, spu_store_registers, spu_xfer_partial) (spu_search_memory, spu_mourn_inferior): Simplify delegation. * linux-thread-db.c (thread_db_pid_to_str): Always delegate. * windows-nat.c (windows_xfer_partial): Always delegate. * record-btrace.c (record_btrace_xfer_partial): Simplify delegation.

This patch moves exec_make_note_section a bit earlier in exec.c.

2014-07-16gdb.trace/tfile.c: Remove Thumb bit in one more more, general cleanupPedro Alves3-36/+97
I noticed that the existing code casts a function's address to 'long', but that doesn't work correctly on some ABIs, like Win64, where long is 32-bit and while pointers are 64-bit: func_addr = (long) &write_basic_trace_file; Fixing that showed there's actually another place in the file that writes a function address to file, and therefore should clear the Thumb bit. This commit adds a macro+function pair to centralize the Thumb bit handling, and uses it in both places. The rest is just enough changes to make the file build without warnings with "-Wall -Wextra" with x86_64-w64-mingw32-gcc and i686-w64-mingw32-gcc cross compilers, and with -m32/-m64 on x86_64 GNU/Linux.
