2016-09-07fortran: combine subarray and string computationChristoph Weinmann1-9/+1
Strings types are handled like array types with only one dimension. Therefore the same algorithm to calculate subsets is used. 2013-11-26 Christoph Weinmann <christoph.t.weinmann@intel.com> * eval.c (evaluate_subexp_standard): Call value_f90_subarray for print expressions on array and string types.

2016-09-07fortran: allow multi-dimensional subarraysChristoph Weinmann4-97/+379
Add an argument count for subrange expressions in Fortran. Based on the counted value calculate a new array with the elements specified by the user. First parse the user input, secondly copy the desired array values into the return array, thirdly re-create the necessary ranges and bounds. 1| program prog 2| integer :: ary(10,5) = (/ (i,i=1,10) (j, j=1,5) /) 3| end program prog (gdb) print ary(2:4,1:3) old> Syntax error in expression near ':3' new> $3 = ( ( 21, 31, 41) ( 22, 32, 42) ( 23, 33, 43) ) 2013-11-25 Christoph Weinmann <christoph.t.weinmann@intel.com> * eval.c (multi_f77_subscript): Remove function. * eval.c (evaluate_subrange_expr): When evaluating an array or string expression, call value_f90_subarray. * eval.c (value_f90_subarray): Add argument parsing and compute result array based on user input. * f-exp.y: Increment argument counter for every subrange expression entered by the user. * valops.c (value_slice): Call value_slice_1 with additional default argument. * valops.c (value_slice_1): Add functionality to copy and return result values based on input. * value.h: Add function definition.

2016-07-08MIPS/GAS: Remove extraneous `install_insn' call from `append_insn'Maciej W. Rozycki1-1/+0
Complement: commit 1e91584932efd70020c8c98037d0cb93a0552a20 Author: Richard Sandiford <rdsandiford@googlemail.com> Date: Wed Mar 9 09:17:02 2005 +0000 <https://sourceware.org/ml/binutils/2005-03/msg00217.html>, ("Rework MIPS nop-insertion code, add -mfix-vr4130 [5/11]"), and remove a call to `install_insn' from `append_insn', which as from that change has become redundant. This is because such a call, to place an instruction's bit pattern in output, is already made from `move_insn', called from `add_relaxed_insn' or `add_fixed_insn' as appropriate, either of which now always is and has to be made from `append_insn' before the repeated call to `install_insn' is made. Previously the place where this second invocation is made was the only one where the output stream was updated, although the update was made inline rather than with a function call. Remove the repeated call then, to reclaim some performance. gas/ * config/tc-mips.c (append_insn): Remove extraneous `install_insn' call.

2016-07-07[obv] Fix broken build on Fedora 23.Walfred Tedeschi2-0/+7

2016-07-07Fix of default lookup for "this" symbol.Walfred Tedeschi5-4/+57
Using the default lookup for the symbol "this" might lead to segmentation fault in GDB. Some languages, e.g. Fortran, use as default lookup routine the C++ routines. For those languages "this" can be the instance of a class or even the definition of a class. When an instance of a class having the name "this" is evaluated in GDB a segmentation fault was observed. As example of the issue take into consideration the Fortran code: type foo real :: a type(bar) :: x character*7 :: b end type foo type(foo) :: this Issue appears when evaluating the variable "this" in GDB. Within the language definition structure there is a field that represents the name of the special symbol used for the C++ "this" for the language being described. The fix presented here takes into account the aforementioned field. In the case the aforementioned field is NULL "this" is not represented in the language described and the lookup should return a null_block_symbol. Tests: Performed tests with gfortran and ifort. Reviewed: https://sourceware.org/ml/gdb-patches/2016-04/msg00068.html After the commited patch: https://sourceware.org/ml/gdb-patches/2016-06/msg00364.html Patch can be applied. 2016-06-16 Walfred Tedeschi <walfred.tedeschi@intel.com> gdb/ChangeLog: * cp-namespace.c (cp_lookup_bare_symbol): Use language passed as parameter to look for the symbol "this". gdb/testsuite/ChangeLog: * gdb.fortran/derived-types.exp (result_line, result_line_2): New variables.

2016-07-06gdb.ada/arraydim.exp: Fix directory layoutSimon Marchi2-2/+7
I forgot to fix this one in the previous commit. gdb/testsuite/ChangeLog: * gdb.ada/arraydim.exp: Remove extra directory level in build directory.
2016-07-06Remove extra output directory level for Ada testsSimon Marchi5-12/+17
The output of Ada tests create a layout where the test name ("formatted_ref" in this example) appears twice: outputs └── gdb.ada └── formatted_ref └── formatted_ref ├── b~formatted_ref.adb ├── b~formatted_ref.ads ├── b~formatted_ref.ali ├── b~formatted_ref.o ├── defs.ali ├── defs.o ├── formatted_ref ├── formatted_ref.ali └── formatted_ref.o This causes a problem when testing with the native-gdbserver board, when the binary has the same name as the test. When gdb_remote_download is called to upload the compiled binary, the implementation for native-gdbserver copies it in the standard output directory (in outputs/gdb.ada/formatted_ref). However, there is already a directory named formatted_ref in there, so the copy fails and gdbserver isn't able to load the binary. This patch bypasses the problem by removing the extra directory level. The compiled binary will already be in its final location in the standard output directory, so the copy will effectively be a no-op. gdb/testsuite/ChangeLog: * lib/ada.exp: Remove extra directory level in build directory. * gdb.ada/cond_lang.exp: Likewise. * gdb.ada/exec_changed.exp: Likewise. * gdb.ada/lang_switch.exp: Likewise.

2016-07-06[ARM] Fix endless recursion on calculating CPRC candidateYao Qi2-2/+10
When GDB determines whether type T can be part of candidate for passing and returning in VFP registers, it calls arm_vfp_cprc_sub_candidate recursively. However, if type T has self-reference field, like, class C { static C s; }; arm_vfp_cprc_sub_candidate won't return. This fix is to skip calling arm_vfp_cprc_sub_candidate if the field is static. gdb: 2016-07-06 Yao Qi <yao.qi@linaro.org> * arm-tdep.c (arm_vfp_cprc_sub_candidate): Don't call arm_vfp_cprc_sub_candidate for static field.

2016-07-01Optimize memory_xfer_partial for remoteDon Breazeal5-2/+58
Some analysis we did here showed that increasing the cap on the transfer size in target.c:memory_xfer_partial could give 20% or more improvement in remote load across JTAG. Transfer sizes were capped to 4K bytes because of performance problems encountered with the restore command, documented here: https://sourceware.org/ml/gdb-patches/2013-07/msg00611.html and in commit 67c059c29e1f ("Improve performance of large restore commands"). The 4K cap was introduced because in a case where the restore command requested a 100MB transfer, memory_xfer_partial would repeatedy allocate and copy an entire 100MB buffer in order to properly handle breakpoint shadow instructions, even though memory_xfer_partial would actually only write a small portion of the buffer contents. A couple of alternative solutions were suggested: * change the algorithm for handling the breakpoint shadow instructions * throttle the transfer size up or down based on the previous actual transfer size I tried implementing the throttling approach, and my implementation reduced the performance in some cases. This patch implements a new target function that returns that target's limit on memory transfer size. It defaults to ULONGEST_MAX bytes, because for native targets there is no marshaling and thus no limit is needed. For remote targets it uses get_memory_write_packet_size. gdb/ChangeLog: * remote.c (remote_get_memory_xfer_limit): New function. * target-delegates.c: Regenerate. * target.c (memory_xfer_partial): Call target_ops.to_get_memory_xfer_limit. * target.h (struct target_ops) <to_get_memory_xfer_limit>: New member.
2016-07-01[AArch64] Fix +nofp16 handlingSzabolcs Nagy7-21/+105
Feature flag handling was not perfect, +nofp16 disabled fp instructions too. New feature flag macros were added to check features with multiple bits set (matters for FP_F16 and SIMD_F16 opcode feature tests). The unused AARCH64_OPCODE_HAS_FEATURE was removed, all checks should use one of the AARCH64_CPU_HAS_* macros. AARCH64_CPU_HAS_FEATURE now checks all feature bits. The aarch64_features table now contains the dependencies as a separate field (so when the feature is enabled all dependencies are enabled and when it is disabled everything that depends on it is disabled). Note that armv8-a+foo+nofoo is not equivalent to armv8-a if +foo turns on dependent features that nofoo does not turn off. gas/ * config/tc-aarch64.c (struct aarch64_option_cpu_value_table): Add require field. (aarch64_features): Initialize require fields. (aarch64_parse_features): Handle dependencies. (aarch64_feature_enable_set, aarch64_feature_disable_set): New.

2016-07-01Fake VFORK_DONE events when following only the parent after a vfork.John Baldwin2-9/+121
FreeBSD does not currently report a ptrace event for a parent process after it resumes due to the child exiting the shared memory region after a vfork. Take the same approach used in linux-nat.c in this case of sleeping for a while and then reporting a fake VFORK_DONE event. gdb/ChangeLog: * fbsd-nat.c (struct fbsd_fork_child_info): Rename to ...

(fbsd_follow_fork): Delay and record a pending vfork done event for a vfork parent when detaching the child.
