2017-01-20Fix uppercase test names in gdb.python/py-xmethods.expLuis Machado2-20/+31
Some leftover uppercase test names in py-xmethods.exp. The patch also replaces two "continue" calls with untested calls to make things a bit more clear. gdb/testsuite/ChangeLog: 2017-01-20 Luis Machado <lgustavo@codesourcery.com> * gdb.python/py-xmethods.exp: Fix test names starting with lowercase and add untested calls.
2017-01-20Make gdb.python/python.exp more robustLuis Machado2-1/+20
I noticed gdb.python/python.exp failing on aarch64-elf like so: FAIL: gdb.python/python.exp: Test decode_line func1 line number This particular test expects the line number for func1 to be 19, hardcoded. In my aarch64-elf tests gdb thinks func1 is at line 20, making the test fail. The following patch addresses this by reading the line number information from GDB and comparing it against the python decoded symtab information. gdb/testsuite/ChangeLog: 2017-01-20 Luis Machado <lgustavo@codesourcery.com> * gdb.python/python.exp: Check line number against what GDB thinks the line number is for func1.
2017-01-20Add command to erase all flash memory regionsLuis Machado9-0/+122
Changes in v4: - Replaced phex call with hex_string. Changes in v3: - Addressed comments by Pedro. - Output of memory region size now in hex format. - Misc formatting fixups. - Addressed Simon's comments on formatting. - Adjusted command text in the manual entry. - Fixed up ChangeLog. - Renamed flash_erase_all_command to flash_erase_command. Changes in v2: - Added NEWS entry. - Fixed long lines. - Address printing with paddress. Years ago we contributed flash programming patches upstream. The following patch is a leftover one that complements that functionality by adding a new command to erase all reported flash memory blocks. The command is most useful when we're dealing with flash-enabled targets (mostly bare-metal) and we need to reset the board for some reason. The wiping out of flash memory regions should help the target come up with a known clean state from which the user can load a new image and resume debugging. It is convenient enough to do this from the debugger, and there is also an MI command to expose this functionality to the IDE's. gdb/doc/ChangeLog: 2017-01-20 Mike Wrighton <mike_wrighton@codesourcery.com> Luis Machado <lgustavo@codesourcery.com> * gdb.texinfo (-target-flash-erase): New MI command description.

2017-01-20objdump: Better objdump section headers in wide modeAndrew Burgess4-9/+59
When displaying the section headers table using objdump (-h), the column containing the section header name is currently fixed at 13 characters. A section name that is longer than 13 characters will overflow the column causing the table to become miss-aligned. In this commit I change the behaviour so that _in wide mode_ (-w -h) the section name column is dynamically resized to fit the longest section name we plan to display. In wide mode the column still retains a minimum width of 13 characters. In non-wide more the behaviour is completely unchanged. While I was changing the dump_headers function I have unified the two printf lines that handled the different address widths into a single printf, the address width is now passed into printf using the '*' field width format character. binutils/ChangeLog: * objdump.c (dump_section_header): Extract max section name length from data parameter, use this when formatting output. (find_longest_section_name): New function. (dump_headers): Calculate longest section name when in wide mode, reformat to unify printing of header line. ld/ChangeLog: * testsuite/ld-elf/eh-frame-hdr.d: Update expected results.
2017-01-20fix gdbserver build in nat/linux-ptrace.c on arm-androidJoel Brobecker2-0/+7
The following change replaced an include of gregset.h by an include of <sys/procfs.h>: commit 39b22471578843019026c50fcdbe0483a6045970 Date: Thu Aug 11 12:01:22 2016 +0100 Subject: Fix fallout from gdb/20413's fix (x32: linux_ptrace_test_ret_to_nx: Cannot PTRACE_PEEKUSER) Unfortunately, this broke gdbserver on Android, because that file does not exist on this platform. This patch fixes the issue by conditionalizing its include with HAVE_SYS_PROCFS_H (which we check both in gdb/configure and gdbserver/configure). gdb/ChangeLog: * nat/linux-ptrace.c: Only include <sys/procfs.h> if HAVE_SYS_PROCFS_H is defined. Tested by rebuilding gdbserver on arm-android and GNU/Linux.

2017-01-18PR ld/20828: Fix linker script symbols wrongly forced local with section GCMaciej W. Rozycki10-3/+123
Fix a generic ELF linker regression introduced with a chain of changes made to unused input section garbage collection: - commit 1a766c6843ce ("Also hide symbols without PLT nor GOT references."), <https://sourceware.org/ml/binutils/2011-09/msg00076.html>, - commit 1d5316ab67e1 ("PR ld/13177: garbage collector retains zombie references to external libraries"), <https://sourceware.org/ml/binutils/2011-10/msg00161.html>, - commit 6673f753c019 ("Fix PR 12772, garbage collection of dynamic syms"), <https://sourceware.org/ml/binutils/2011-12/msg00077.html>, causing the garbage collection of unused symbols present in a DSO involved in a link to make identically named symbols ordinarily defined (i.e. not hidden or PROVIDEd) by a linker script local, even though the latter symbols are supposed to be global as if no DSO defined them as well. This is because linker script assignments are processed very late as `lang_process' proceeds, down in the call to `ldemul_before_allocation', which is made after the call to `lang_gc_sections' to do input section garbage collecting. Consequently if unused, then any such DSO-defined symbol has already been garbage-collected and internally marked local. It would ordinarily be removed from dynamic symbol table output, however a linker script assignment correctly replaces its original definition with the new one and enters it into the dynamic symbol table produced as it is supposed to be exported. The original local marking is however retained making the symbol local in the dynamic symbol table and therefore not available externally. This also causes a sorting problem with the MIPS target, which does not expect non-section local dynamic symbols to be output and produces an invalid binary. Fix the problem then, by removing the `forced_local' marking for the offending case and add suitable test cases. First to verify that unused symbols ordinarily defined with linker script assignments remain exported in the context of input section garbage collection whether or not a DSO defining identically named symbols is present in the link. Second that a linker version script still correctly retains or removes such symbols as requested. bfd/ PR ld/20828 * elflink.c (bfd_elf_record_link_assignment): Clear any `forced_local' marking for DSO symbols that are not being provided. ld/ PR ld/20828 * testsuite/ld-elf/pr20828-1.sd: New test. * testsuite/ld-elf/pr20828-2a.sd: New test. * testsuite/ld-elf/pr20828-2b.sd: New test. * testsuite/ld-elf/pr20828.ld: New test linker script. * testsuite/ld-elf/pr20828.ver: New test version script. * testsuite/ld-elf/pr20828.s: New test source. * testsuite/ld-elf/shared.exp: Run the new test.
2017-01-18PR gas/20649: MIPS: Fix GOT16/LO16 reloc pairing with comdat sectionsMaciej W. Rozycki7-5/+102
Correct a regression from commit 8614eeee67f9 ("Traditional MIPS patches"), <https://sourceware.org/ml/binutils/2000-07/msg00018.html>, which caused symbols in linkonce or what is these days known as comdat sections to be treated as external for the purpose of PIC relocation generation even if their binding remains STB_LOCAL. This in turn disabled GOT16/LO16 relocation pairing with references to such symbols, as no complementing LO16 relocation is expected for external GOT16 references in the o32 ABI, which ultimately leads to link errors, e.g.: ld: comdat-reloc.o: Can't find matching LO16 reloc against `foo' for R_MIPS_GOT16 at 0x24 in section `.text.bar[bar]' as with the LD test case included with this change. Revert the special case for symbols in comdat sections then, making code actually match `adjust_reloc_syms' as indicated in its explanatory comment, and adjust calling code accordingly. Also bring back the corresponding description of what now is `s_is_linkonce', lost with commit 5f0fe04bc550 ("Improved MIPS16/MIPS32 code intermixing for gas."), <https://www.sourceware.org/ml/binutils/2006-07/msg00039.html>. gas/ PR gas/20649 * config/tc-mips.c (pic_need_relax): Don't check for linkonce symbols, remove the `segtype' parameter.

When I inspect the return values of disassmblers, I happen to see various -1/-2/-3 magic numbers are used in m68k-dis.c. This patch is to replace them with enum. -1 and -2 is "clearly documented" in print_ins_arg's comments, but -3 isn't. In fact, -3 is returned when FETCH_DATA returns false, which means memory error (because fetch_data return 0 on memory error). So I name enum PRINT_INSN_ARG_MEMORY_ERROR for -3.

2017-01-12Update comment in remote_can_async_pSimon Marchi2-1/+6
I find this comment counter intuitive, and it probably predates the always-target-async change. AFAIK, remote will always be async, unless the user explicitly prevents it with "maint set target-async off". gdb/ChangeLog: * remote.c (remote_can_async_p): Update comment.

2017-01-12Remove dead serial_interface_lookup callsSimon Marchi2-5/+5
By inspecting the serial_add_interface calls, I found that the serial interface names that we have today are: - hardwire - terminal - pipe - tcp - event The calls to serial_interface_lookup with any other names are most likely leftovers which can be removed since these serial interfaces don't exist anymore. The commits that removed the "pc" and "parallel" interfaces are respectively: cb2a4ac5dae478fcd9d6e772530c3aba0576fc7a and e386d4d2fb55042f77d0557a0849ed2464aee7b3 gdb/ChangeLog: * serial.c (serial_open): Forget about "pc" and "lpt" serial interface.

2017-01-12Return -1 on memory error in print_insn_msp430Yao Qi2-14/+99
Disassemblers in opcodes return -1 on memory error, but msp430 doesn't follow this convention. If I change GDB not to throw exception in disassemble_info.memory_error_func and rely on the return value of disassembler, I'll get the following output. (gdb) disassemble 0x0,+8 Dump of assembler code from 0x0 to 0x8: 0x00000000: .word 0xffff; ???? 0x00000002: .word 0xffff; ???? 0x00000004: .word 0xffff; ???? 0x00000006: .word 0xffff; ????
