2014-07-02Taking an undefined function's address in an executableAlan Modra10-19/+226

2014-07-02Remove unused Linux libthread_db callbacksGary Benson2-103/+15
gdb/proc-service.c includes several libthread_db callbacks that do not exist in gdb/gdbserver/proc-service.c. Other than in proc_service.h, there is no reference to any of these callbacks in any revision of nptl_db or linuxthreads_db in glibc's git repo so it seems likely that these functions have never been called. This commit removes them. gdb/ 2014-07-02 Gary Benson <gbenson@redhat.com> * proc-service.c (ps_xfer_memory): Update comment. (ps_pstop): Remove unused function. (ps_pcontinue): Likewise.

2014-07-01Add symbols for global entry stub, and report statsAlan Modra4-29/+72
The undefined function symbols (with non-zero value) on global entry stubs are discarded by objdump when disassembling, so give objdump another symbol to mark the stubs. Also fixes a couple of bugs: - entry_section was set to .opd for ELFv2, which meant a hard error rather than a warning when _start wasn't defined. - global entry stubs were not built if they were the only type of stub in an executable. bfd/ * elf64-ppc.c (ppc_stub_type): Add ppc_stub_global_entry. (struct ppc_link_hash_table): Increase size of stub_count array. (build_global_entry_stubs): Emit symbol on global entry stub. (ppc64_elf_build_stubs): NULL check htab->brlt.

Only change entry_section for ELFv1.
2014-07-01Don't include sys/param.hAlan Modra3-23/+8
sys/param.h on recent versions of powerpc glibc ends up including asm/elf.h via asm/sigcontex.h. asm/elf.h defines R_PPC_* and R_PPC64_* macros, which clash with our include/elf/ppc.h and include/elf/ppc64.h. It turns out that no current source uses LD_PATHMAX, so there is no need for limits.h or sys/param.h, except for one occurrence of UINT_MAX. I don't have a quarrel with limits.h, but it seems unnecessary just for UINT_MAX. * sysdep.h: Don't include limits.h and sys/param.h. Don't include unistd.h twice. (LD_PATHMAX): Don't define. * ldlang.c (lang_common): Don't use UINT_MAX.
2014-07-01Linker foreign output format support for PowerPC64 ELFv2Alan Modra2-19/+61
Makes the ld srec tests pass. Uses a horrible scan through symbols to find ELF fields for symbol definitions, but the generic linker doesn't offer anything better. Might be slow. Anyway, sane people will link to ELF output then objcopy to convert formats. * elf64-ppc.c (abiversion, set_abiversion): Move earlier. (ppc64_elf_branch_reloc): Adjust addend for ELFv2 local offset.

2014-06-30watchpoint-reuse-slot.exp: Correctly skip unsupported commands.Andreas Arnez2-1/+12
The test case "watchpoint-reuse-slot.exp" yields a lot of failures on s390/s390x: all instances of awatch, rwatch, and hbreak are performed even though they aren't supported on these targets. This is because the test case ignores non-support error messages when probing for support of these commands, like: (gdb) rwatch buf.byte[0] Target does not support this type of hardware watchpoint. The patch adds handling for this case in the appropriate gdb_test_multiple invocations. gdb/testsuite/ * gdb.base/watchpoint-reuse-slot.exp: Handle the case that the target lacks support for awatch, rwatch, or hbreak.

2014-06-27Associate dummy_frame with ptidYao Qi13-45/+236
This patch is to add ptid into dummy_frame and extend frame_id to dummy_frame_id (which has a ptid field). With this change, GDB uses dummy_frame_id (thread ptid and frame_id) to find the dummy frames. Currently, dummy frames are looked up by frame_id, which isn't accurate in non-stop or multi-process mode. The test case gdb.multi/dummy-frame-restore.exp shows the problem and this patch can fix it. Test dummy-frame-restore.exp makes two inferiors stop at different functions, say, inferior 1 stops at f1 while inferior 2 stops at f2. Set a breakpoint to a function, do the inferior call in two inferiors, and GDB has two dummy frames of the same frame_id. When the inferior call is finished, GDB will look up a dummy frame from its stack/list and restore the inferior's regcache. Two inferiors are finished in different orders, the inferiors' states are restored differently, which is wrong. Running dummy-frame-restore.exp under un-patched GDB, we'll get two fails: FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 2 FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 1 With this patch applied, GDB will choose the correct dummy_frame to restore for a given inferior, because ptid is considered when looking up dummy frames. Two fails above are fixed.

2014-06-26fix memory errors with demangled name hashTom Tromey2-23/+44
This fixes a regression that Jan pointed out. The bug is that some names were allocated by dwarf2read on the objfile obstack, but then passed to SYMBOL_SET_NAMES with copy_name=0. This violates the invariant that the names must have a lifetime tied to the lifetime of the BFD. The fix is to allocate names on the per-BFD obstack. I looked at all callers, direct or indirect, of SYMBOL_SET_NAMES that pass copy_name=0. Note that only the ELF and DWARF readers do this; other symbol readers were never updated (and perhaps cannot be, depending on the details of the formats). This is why the patch is relatively small.

Prior to 93d1b056 _SDA_BASE_ used to be defined in a linker script output section. Now _SDA_BASE_ is defined in an input section that is subject to being stripped. If the section is stripped we don't output the symbol, which results in --emit-relocs trying to emit relocs with dangling references to _SDA_BASE_. * elf32-ppc.c (ppc_elf_size_dynamic_sections): Arrange to keep .sdata/.sdata2 when _SDA_BASE_/_SDA2_BASE_ should be output for --emit-relocs.
2014-06-24Skip 'bx reg' on arm-linuxYao Qi2-1/+21
In arm-tdep.c, arm_skip_stub is installed to gdbarch skip_trampoline_code, but in arm-linux-tdep.c, find_solib_trampoline_target is installed to skip_trampoline_code. That means gdb configured for arm-linux target doesn't recognize some arm specific trampolines or stubs. Beside handling generic solib trampoline, gdb for arm-linux target should be able to handle arm specific trampolines. This patch is to skip arm specific stubs, if any, and as a fallback, skip the generic solib trampoline. gdb: 2014-06-24 Yao Qi <yao@codesourcery.com> * arm-linux-tdep.c (arm_linux_skip_trampoline_code): New. (arm_linux_init_abi): Set skip_trampoline_code with gdbarch_skip_trampoline_code instead of find_solib_trampoline_target.
2014-06-24Apply stub unwinder to 'bx reg' trampolineYao Qi2-1/+13
In target arm-none-eabi, prologue unwinder is used for trampoline 'bx reg'. However, in target arm-linux, exidx unwinder is selected for trampoline at first, which is not expected. The main function and the trampoline is, 0x00009dfc <main+0>: push {r4, r5, r6, r7, lr} ...... 0x0000ac30 <main+3636>: ldrdeq r3, [r1], -r8 0x0000ac34: bx r2 0x0000ac36: bx r4 and .ARM.exidx is: 0x9dfc <main>: @0xb404 Compact model index: 1 0x97 vsp = r7 0x20 vsp = vsp + 132 0x3f vsp = vsp + 256 0x80 0xf0 pop {r8, r9, r10, r11} 0xab pop {r4, r5, r6, r7, r14} 0xac38 <__aeabi_drsub>: 0x1 [cantunwind] Trampolines 'bx r2' and 'bx r4' doesn't belong to main, but the exidx for main is still selected form them because there is no end address of each exidx entry. Instead of teaching exidx unwinder ignore this trampoline (which looks complicated and error prone), I decide to let stub unwinder to handle trampoline, because stub undwinder is installed before exidx unwinder, and this trampoline can be regarded as a stub too. This patch is to add the code to match 'bx reg' trampoline in the sniffer of stub unwinder. gdb: 2014-06-24 Yao Qi <yao@codesourcery.com> * arm-tdep.c (arm_stub_unwind_sniffer): Return 1 if arm_skip_bx_reg returns non-zero.
2014-06-24Skip 'bx reg' trampoline on arm-none-eabiYao Qi2-1/+72
After this patch <https://gcc.gnu.org/ml/gcc-patches/2005-01/msg00813.html> applied to GCC, a new trampoline is generated but GDB doesn't recognize it. This patch is to teach GDB to understand this trampoline. See details about this trampoline and the heuristics in the comments. gdb: 2014-06-24 Yao Qi <yao@codesourcery.com> * arm-tdep.c (arm_skip_bx_reg): New function. (arm_skip_stub): Call arm_skip_bx_reg.
