2016-08-31Handle ILP32 AARCH64 correctly for gdbserverusers/apinski/gdb-ilp32-gdbserverAndrew Pinski12-8/+417
In gdbserver, we need to send over 32bit registers for pc/sp instead of 64bit as we do right now. So we need another XML file for ILP32. Tested using gdbserver with an ILP32 program and even tested using gdbserver as an ILP32 program. OK? Thanks, Andrew Pinski ChangeLog: * aarch64-tdep.c: Include "features/aarch64_ilp32.c". (aarch64_gdbarch_init): Handle ilp32 correctly. (_initialize_aarch64_tdep): Call initialize_tdesc_aarch64_ilp32 too. * features/Makefile (WHICH): Add aarch64_ilp32. (aarch64_ilp32-expedite): Set. (XMLTOC): Add aarch64_ilp32.xml. (features/aarch64_ilp32-core.xml): New file. (features/aarch64_ilp32.xml): New file. (features/aarch64_ilp32.c): Generate. (regformats/aarch64_ilp32.dat): Generate. gdbserver/ChangeLog: * Makefile.in (clean): Remove aarch64_ilp32.c also. (aarch64_ilp32-ipa.o): New target. (aarch64_ilp32.c): New target. * configure.srv (aarch64*-*-linux*): Add ilp32 files to srv_regobj, srv_xmlfiles and ipa_obj. * linux-aarch64-ipa.c (init_registers_aarch64_ilp32): Declare. (tdesc_aarch64_ilp32): Likewise. (get_ipa_tdesc): Return tdesc_aarch64_ilp32 for ILP32. (initialize_low_tracepoint): Call init_registers_aarch64_ilp32 for ILP32. * linux-aarch64-low.c (init_registers_aarch64_ilp32): Declare. (tdesc_aarch64_ilp32): Likewise.

2016-08-31Add ILP32 support to gdb.Andrew Pinski4-4/+30
This patch adds AARCH64:ilp32 support to gdb and sets up the correct sizes for some types like pointers and long. Also sets up the correct linker map offsets for Linux. 2016-08-31 Andrew Pinski <apinski@cavium.com> * aarch64-tdep.h (gdbarch_tdep): Add ilp32 field. * aarch64-tdep.c (aarch64_gdbarch_init): Setup ILP32 support. Make sure the gdbarches have compatible ilp32 flags. Set long and ptr sizes correctly for ilp32. * aarch64-linux-tdep.c (aarch64_linux_init_abi): Add support for ILP32.
2016-08-31Move AARCH64 ILP32 rejection handlingAndrew Pinski3-26/+27
For AARCH64 ILP32, we reject compatibility too early on to support gdb ILP32. This patch moves ILP32 rejection from compatible to elfNN_aarch64_merge_private_bfd_data which allows aarch64 and aarch64:ilp32 to be handled correctly with gdb. An added bonus is that we can have an error message on why two object files are rejected. OK? Tested both binutils and gdb. Thanks, Andrew Pinski 2016-08-31 Andrew Pinski <apinski@cavium.com> * cpu-aarch64.c (compatible): Don't reject different mach or ILP32 here. * elfnn-aarch64.c (elfNN_aarch64_merge_private_bfd_data): Add an error message on why endianess is rejected. Reject different ILP32/LP64 settings. Signed-off-by: Andrew Pinski <apinski@cavium.com>
2016-08-31Fix lwp_suspend/unsuspend imbalance in linux_wait_1Antoine Tremblay2-18/+23
This patch fixes imbalanced lwp_suspend/unsuspend calls caused by the premature choosing of another event for fairness. select_event_lwp would switch the event before a call to unsuspend_all_lwps, thus it would be called with the wrong event. This caused an assertion failure: unsuspend LWP xx, suspended=-1 when testing gdb.threads/non-stop-fair-events.exp with ARM range stepping in GDBServer. This patch moves the switch of event after the unsuspend/unstop calls. No regressions, tested on ubuntu 14.04 ARMv7 and x86. With gdbserver-native. gdb/gdbserver/ChangeLog: * linux-low.c (linux_wait_1): Move event switch after unsuspend_lwps.

2016-08-31[GOLD] Further tidy to powerpc can_add_to_stub_groupAlan Modra2-19/+27
This patch adds a little more debug output, and replaces two variables with one, tracking current max group size by group_size_ rather than by has14_. * powerpc.cc (class Stub_control): Delete stub14_group_size_ and has14_. Add group_size_. (Stub_control::can_add_to_stub_group): Adjust to suit. Print debug info when switching to adding sections before stubs.
2016-08-31PowerPC64, correct grouping of stubs for ld.bfdAlan Modra2-24/+26

Instead, track max group size with a new "group_size" var that is reduced by a factor of 1024 from the 24-bit branch size whenever a 14-bit branch is seen.

2016-08-31PowerPC VLE sh_flags and p_flagsAlan Modra4-42/+71
ELF section sh_flags SHF_PPC_VLE was being set based on arch/mach, which meant all code sections in an object file has the flag or all lacked it. We can do better than that. Only those code sections where VLE is enabled ought to have the flag, allowing an object file to contain both VLE and non-VLE code. Also, ELF header p_flags PF_PPC_VLE wasn't being set, and segments were being split unnecessarily. bfd/ * elf32-ppc.c (ppc_elf_section_processing): Delete. (elf_backend_section_processing): Don't define. (ppc_elf_modify_segment_map): Set p_flags and mark valid. Don't split on non-exec sections differing in SHF_PPC_VLE.

2016-08-30[GOLD] correct grouping of stubsAlan Modra2-33/+81
This patch rewrites the rather obscure can_add_to_stub_group, fixing a problem with the handling of sections containing conditional external branches. When a section group contains any such section, the group size needs to be limited to a much smaller size than groups with only non-conditional external branches. PR 20523 * powerpc.cc (class Stub_control): Add has14_. Comment owner_. (Stub_control::can_add_to_stub_group): Correct grouping of sections containing 14-bit external branches.

2016-08-29i386: Issue an error on non-PIC call to IFUNC in PIC objectH.J. Lu15-44/+101
On i386, IFUNC function must be called via PLT. Since PLT in PIC object uses EBX register, R_386_PLT32 relocation must be used to call IFUNC function even when IFUNC function is defined locally. Linker should issue an error when R_386_PC32 relocation is used to call IFUNC function.

2016-08-25xtensa: Avoid designated inits, for C++ complianceAndreas Arnez2-49/+55
C++ does not officially support designators in initializer lists. Thus some compilers may issue errors when encountering them. Modern versions of GCC seem to allow them by default, as a GCC extension, even though the GCC documentation explicitly states otherwise: "[...] This extension is not implemented in GNU C++." But some older GCC versions (like 4.4.7) did indeed emit an error instead, like this: .../gdb/xtensa-config.c:219: error: expected primary-expression before ‘.’ token This patch removes the only such instance I've seen when building with '--enable-targets=all'. gdb/ChangeLog: * xtensa-tdep.h (XTENSA_GDBARCH_TDEP_INSTANTIATE): Replace designated initializer list by plain initializer list, for C++ compliance.
2016-08-25powerpc ld configureAlan Modra2-32/+74
This fixes a few problems in the powerpc ld configury. 1) Using powerpc*le-* to test for powerpcle and powerpc64le would incorrectly match a target triple like powerpc-apple-elf. 2) In the same vein, *64* could match 64 in the user supplied MANUF-OS part of the target triple. 3) tooldir vars were missing, and some target aliases would result in ridiculous values for those tdir_* vars given. 4) Since 2016-04-25, BE support was added automatically when asking for an LE target. If that is a good idea, then so is adding LE support when asking for BE. * configure.tgt (powerpc*-*-linux* et al): Rewrite, adding LE support for BE. First output all target endian configury values, then opposite endian. Handle more tooldirs. Fix bogus matches with strings in MANUF-OS part of target triple.

2016-08-25Sync proc_service definition with GLIBCAdhemerval Zanella22-20/+49
GLIBC BZ#20311 [1] proc_service.h install patch also remove 'const' attributes from ps_get_thread_area and comment #15 discuss why to remove the const attribute (basically since it a callback with the struct ps_prochandle owned by the client it should be able to modify it if it the case). On default build this is not the issue and current g++ does not trigger any issue with this mismatch declaration. However, on some bootstrap build configuration where gdbserver is build with gcc instead this triggers: error: conflicting types for 'ps_get_thread_area' This patch fixes it by syncing the declaration with GLIBC.

2016-08-24Test case to detect recursive unwinding in Python-based unwinders.Kevin Buettner4-0/+191
This test case verifies that GDB will not attempt to invoke a python unwinder recursively. At the moment, the behavior exhibited by GDB looks like this: (gdb) source py-recurse-unwind.py Python script imported (gdb) b ccc Breakpoint 1 at 0x4004bd: file py-recurse-unwind.c, line 23. (gdb) run Starting program: py-recurse-unwind TestUnwinder: Recursion detected - returning early. TestUnwinder: Recursion detected - returning early. TestUnwinder: Recursion detected - returning early. TestUnwinder: Recursion detected - returning early. Breakpoint 1, ccc (arg=<unavailable>) at py-recurse-unwind.c:23 23 } (gdb) bt #-1 ccc (arg=<unavailable>) at py-recurse-unwind.c:23 Backtrace stopped: previous frame identical to this frame (corrupt stack?) [I've shortened pathnames for easier reading.] The desired / expected behavior looks like this: (gdb) source py-recurse-unwind.py Python script imported (gdb) b ccc Breakpoint 1 at 0x4004bd: file py-recurse-unwind.c, line 23. (gdb) run Starting program: py-recurse-unwind Breakpoint 1, ccc (arg=789) at py-recurse-unwind.c:23 23 } (gdb) bt #0 ccc (arg=789) at py-recurse-unwind.c:23 #1 0x00000000004004d5 in bbb (arg=456) at py-recurse-unwind.c:28 #2 0x00000000004004ed in aaa (arg=123) at py-recurse-unwind.c:34 #3 0x00000000004004fe in main () at py-recurse-unwind.c:40 Note that GDB's problems go well beyond the fact that it invokes the unwinder recursively. In the process it messes up some internal state (the frame stash) leading to display of (only) the sentinel frame in the backtrace. gdb/testsuite/ChangeLog: * gdb.python/py-recurse-unwind.c: New file. * gdb.python/py-recurse-unwind.py: New file. * gdb.python/py-recurse-unwind.exp: New file.
