2015-12-09varobj zero-padded hexadecimal formatLuis Machado9-7/+65
This set of patches add support for the zero-padded hexadecimal format for varobj's, defined as "zero-hexadecimal". We currently only support regular non-zero-padded hexadecimal. Talking with IDE developers, they would like to have this option that is already available to GDB's print/x commands, in the CLI, as 'z'. gdb/ChangeLog: 2015-12-09 Luis Machado <lgustavo@codesourcery.com> * gdb/mi/mi-cmd-var.c (mi_parse_format): Handle new "zero-hexadecimal" format. * gdb/varobj.c (varobj_format_string): Add "zero-hexadecimal" entry.

2015-12-09sparc: support %dN and %qN syntax for FP registers.Jose E. Marchesi2-5/+16
The SPARC Refence Manual documents the %dN and %qN syntax to refer to double and quad-precision floating-point registers, respectively. See OSA2015 Appendix C, Assembly Language Syntax, C1.1 Register Names. This patch adds support for these names to GAS. This eases the porting of software from Solaris to GNU/Linux, as these register names have been supported by the Solaris linker for a long time and many assembler require that support. gas/ChangeLog: 2015-12-09 Jose E. Marchesi <jose.marchesi@oracle.com> * config/tc-sparc.c (sparc_ip): Support %dN and %qN notation for double and quad-precision floating-point registers.
2015-12-09Fix wrong output of x87 registers due to truncation to double on amd64Ruslan Kabatsayev5-5/+37
When `info float` is used on an AMD64 system, GDB prints floating-point values of x87 registers with raw contents like 0x361a867a8e0527397ce0 or 0xc4f988454a1ddd3cfdab wrongly. This happens due to truncation to double, after which the former becomes 0.0, and the latter becomes negative infinity. This is caused by failed detection of x86-64 host, which results in setting gdb_host_{float,double,long_double}_format to zeros. This commit fixes this misdetection, and adds a test to make sure future commits don't introduce a regression here. gdb/ChangeLog: 2015-12-09 Ruslan Kabatsayev <b7.10110111@gmail.com> PR gdb/18702 * configure.host: Fix detection of x86_64 host when setting floatformats. gdb/testsuite/ChangeLog: 2015-12-09 Ruslan Kabatsayev <b7.10110111@gmail.com> Pedro Alves <pedro@redhat.com> PR gdb/18702 Add checking of floatformats setup on x86_64 hosts. * gdb.arch/i386-float.S (main): Load bigval and smallval.

2015-12-09[GOLD] Relocate::relocate() paramsAlan Modra16-229/+146
Some linker code editing needs to change multiple insns. In some cases multiple relocations are involved and it is not sufficient to make the changes independently as relocations are processed, because doing so might lead to a partial edit. So in order to safely edit we need all the relocations available in relocate(). Also, to emit edited relocs corresponding to the edited code sequence we need some way to pass information from relocate() to relocate_relocs(), particularly if the edit depends on insns. We can't modify input relocs in relocate() as they are mmapped PROT_READ, nor it is particularly clean to write relocs to the output at that stage. So add a Relocatable_relocs* field to relinfo to mark edited relocs. Given that relocate is passed the raw reloc pointer, it makes sense to remove the rel/rela parameter and r_type too. However, that means the mips relocate() needs to know whether SHT_REL or SHT_RELA relocs are being processed. So add a rel_type for mips, which also has the benefit of removing relocate() overloading there. This patch adds the infrastructure without making use of it. Note that relinfo->rr will be NULL if not outputting relocations. * object.h (struct Relocate_info): Add "rr". * reloc.h (Relocatable_relocs::set_strategy): New accessor. * reloc.cc (Sized_relobj_file::do_relocate_sections): Init relinfo.rr for relocate_section and relocate_relocs. * powerpc.cc (relocate): Add rel_type and preloc parameters.

While not allowed, this certainly shouldn't result in confusing the programmer (by skipping lines in unexpected ways): Without returning, demand_empty_rest_of_line() (at the end of the function) will demand the _next_ line to be empty, and without the conditional we would ignore the next line.

2015-12-07Support Z0 packet in AArch64 multi-arch debuggingYao Qi8-181/+243
In commit 6085d6f6, Z0 packet is disabled in aarch64 GDBserver if the inferior is 32-bit or there may be multiple inferiors, because Z0 packet isn't supported for arm then. Recently, Z0 packet is supported in arm target, so we don't have such limitation in aarch64 GDBserver, that is to say, aarch64 GDBserver can use Z0 packet in multi-arch/multi-inferior debugging when the inferior's arch is arm. Part of this patch is to revert 6085d6f6, and the rest of the patch is to move some breakpoint related arm_* functions into linux-aarch32-low.c in order to share them between arm and aarch64. This patch is regression tested on aarch64-linux for debugging both aarch64 programs and arm programs respectively. gdb/gdbserver: 2015-12-07 Yao Qi <yao.qi@linaro.org> * configure.srv: Append arm.o to srv_tgtobj for aarch64*-*-linux* target. * linux-aarch32-low.c (arm_abi_breakpoint): New macro.

2015-12-07Enhance the menu to select function overloads with signaturesPierre-Marie de Rodat5-23/+212
So far, trying to evaluate an expression involving a function call for which GDB could find multiple function candidates outputs a menu so that the user can select the one to run. For instance, with the two following functions: type New_Integer is new Integer; function F (I : Integer) return Boolean; function F (I : New_Integer) return Boolean; Then we get the following GDB session: (gdb) print f(1) Multiple matches for f [0] cancel [1] foo.f at foo.adb:23 [2] foo.f at foo.adb.28 > While the source location information is sufficient in order to determine which one to select, one has to look for them in source files, which is not convenient. This commit tunes this menu in order to also include the list of formal and return types (if any) in each entry. The above then becomes: (gdb) print f(1) Multiple matches for f [0] cancel [1] foo.f (integer) return boolean at foo.adb:23 [2] foo.f (foo.new_integer) return boolean at foo.adb.28 > Since this output is more verbose than previously, this change also introduces an option (set/show ada print-signatures) to get the original output. gdb/ChangeLog: * ada-lang.c (print_signatures): New. (ada_print_symbol_signature): New. (user_select_syms): Add signatures to the output of candidate symbols using ada_print_symbol_signature.

On 32-bit targets, memory requested for program/section headers on a fuzzed binary can wrap to 0. A bfd_alloc of zero bytes actually returns a one byte allocation rather than a NULL pointer.

2015-12-03Remove duplicate arch/arm.h include in linux-arm-low.c.Antoine Tremblay2-2/+4
A duplicate include arm/arm.h was introduced, remove it. Pushed as obvious. gdb/gdbserver/ChangeLog: * linux-arm-low.c: Remove duplicate arch/arm.h include.
2015-12-03Run gdb.base/sizeof.exp with board having gdb,noinferiorioYao Qi3-39/+31
In my remote cross testing (x86_64 host and aarch64 target), the test gdb.base/sizeof.exp is skipped because gdb,noinferiorio is defined in my gdbserver board file. Tests are skipped because the test checks the expected value from the program's output, but I don't see why must do it this way. With my patch applied, we can save the result in variable in the program, and check the variable then. Then, the test doesn't rely on inferiorio. gdb/testsuite: 2015-12-03 Yao Qi <yao.qi@linaro.org> * gdb.base/sizeof.c: Don't include stdio.h and ../lib/unbuffer_output.c. (main): New variable 'size' and 'value'. Remove printf and gdb_unbuffer_output. Assign return value to size and value. * gdb.base/sizeof.exp: Remove the checking to gdb,noinferiorio at the beginning. (check_sizeof): Check the result by printing variable 'size'. (check_valueof): Check the result by printing variable 'value'.

2015-12-02addr2line vs. inlined C functions called from C++Alan Modra3-14/+31
In this case the inlined function doesn't have DW_AT_linkage_name in .debug_info, but the language is C++ so find_nearest_line goes looking in the symbol table. Since the function is inlined the enclosing non-inline function symbol is returned from _bfd_elf_find_function, which is wrong. This patch only uses a symbol if its address matches. PR binutils/19315 * dwarf2.c (_bfd_elf_find_function): Return symbol matched. (_bfd_dwarf2_find_nearest_line): Check symbol returned above against dwarf range. * elf-bfd.h (_bfd_elf_find_function): Update prototype.
