2015-11-30objdump: Handle 32-bit base address in debug_ranges / debug_loc.Andrew Burgess6-11/+207
When the DWARF address size is 32-bit, but the host machine is 64-bit, objdump fails to spot base addresses specified in the .debug_ranges and .debug_loc lists. As an example, here is the output when dumping an example .debug_ranges section with the pre-patched objdump: Contents of the .debug_ranges section: Offset Begin End 00000000 ffffffff 00000004 (start > end) 00000000 00000000 00000004 00000000 ffffffff 00000008 (start > end) 00000000 00000000 00000004 00000000 <End of list> And this is what the same section looks like when dumped with the patched version of objdump: Contents of the .debug_ranges section: Offset Begin End 00000000 ffffffff 00000004 (base address) 00000000 00000004 00000008 00000000 ffffffff 00000008 (base address) 00000000 00000008 0000000c 00000000 <End of list> binutils/ChangeLog: * dwarf.c (is_max_address): New function.

2015-11-28PR other/61321 - demangler crash on casts in template parametersPedro Alves5-8/+81
The fix for bug 59195: [C++ demangler handles conversion operator incorrectly] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59195 unfortunately makes the demangler crash due to infinite recursion, in case of casts in template parameters. For example, with: template<int> struct A {}; template <typename Y> void function_temp(A<sizeof ((Y)(999))>) {} template void function_temp<int>(A<sizeof (int)>); The 'function_temp<int>' instantiation above mangles to: _Z13function_tempIiEv1AIXszcvT_Li999EEE The demangler parses this as: typed name template name 'function_temp' template argument list builtin type int function type builtin type void argument list template (*) name 'A' template argument list unary operator operator sizeof unary operator cast template parameter 0 (**) literal builtin type int name '999' And after the fix for 59195, due to: static void d_print_cast (struct d_print_info *dpi, int options, const struct demangle_component *dc) { ... /* For a cast operator, we need the template parameters from the enclosing template in scope for processing the type. */ if (dpi->current_template != NULL) { dpt.next = dpi->templates; dpi->templates = &dpt; dpt.template_decl = dpi->current_template; } when printing the template argument list of A (what should be "<sizeof (int)>"), the template parameter 0 (that is, "T_", the '**' above) now refers to the first parameter of the the template argument list of the 'A' template (the '*' above), exactly what we were already trying to print. This leads to infinite recursion, and stack exaustion. The template parameter 0 should actually refer to the first parameter of the 'function_temp' template. Where it reads "for the cast operator" in the comment in d_print_cast (above), it's really talking about a conversion operator, like: struct A { template <typename U> explicit operator U(); }; We don't want to inject the template parameters from the enclosing template in scope when processing a cast _expression_, only when handling a conversion operator. The problem is that DEMANGLE_COMPONENT_CAST is currently ambiguous, and means _both_ 'conversion operator' and 'cast expression'. Fix this by adding a new DEMANGLE_COMPONENT_CONVERSION component type, which does what DEMANGLE_COMPONENT_CAST does today, and making DEMANGLE_COMPONENT_CAST just simply print its component subtree. I think we could instead reuse DEMANGLE_COMPONENT_CAST and in d_print_comp_inner still do: @@ -5001,9 +5013,9 @@ d_print_comp_inner (struct d_print_info *dpi, int options, d_print_comp (dpi, options, dc->u.s_extended_operator.name); return; case DEMANGLE_COMPONENT_CAST: d_append_string (dpi, "operator "); - d_print_cast (dpi, options, dc); + d_print_conversion (dpi, options, dc); return; leaving the unary cast case below calling d_print_cast, but seems to me that spliting the component types makes it easier to reason about the code. g++'s testsuite actually generates three symbols that crash the demangler in the same way. I've added those as tests in the demangler testsuite as well. And then this fixes PR other/61233 too, which happens to be a demangler crash originally reported to GDB, at: https://sourceware.org/bugzilla/show_bug.cgi?id=16957 Bootstrapped and regtested on x86_64 Fedora 20. Also ran this through GDB's testsuite. GDB will require a small update to use DEMANGLE_COMPONENT_CONVERSION in one place it's using DEMANGLE_COMPONENT_CAST in its sources. libiberty/ 2015-11-27 Pedro Alves <palves@redhat.com> PR other/61321 PR other/61233 * demangle.h (enum demangle_component_type) <DEMANGLE_COMPONENT_CONVERSION>: New value. * cp-demangle.c (d_demangle_callback, d_make_comp): Handle DEMANGLE_COMPONENT_CONVERSION.

2015-11-27[AArch64][PATCH 2/3] Adjust a utility function for floating point values.Matthew Wahab2-7/+37
ARMv8.2 adds 16-bit floating point operations as an optional extension. This patch adjusts the utility function expand_fp_imm to support 16-bit values. The function is intended to convert an 8-bit immediate representing a floating point value to a representation that can be passed to fprintf. Because of the limited use of the results, the only change made to the function is to treat a request for a 16-bit float as a request for a 32-bit float. opcodes/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64-opc.c (half_conv_t): New.

2015-11-27[AArch64] Add ARMv8.2 instructions BFC and REV64.Matthew Wahab13-861/+1106
ARMv8.2 adds two new instructions: BFC as an alias for BFM and REV64 as an alias for REV. This patch set adds support for these to binutils, enabled when the -march=armv8.2-a is given. It depends on the support for an instruction being its preferred form which was added in an earlier patch. This patch adds the alias BFC <Rd>, #<imm>, #<width> as the preferred form for BFM when the source is a zero register and the conditions for using the BFI form are met (in other words, BFC is the preferred form for BFI <Rd>, <Rs>, #<imm>, #<width> when the <Rs> is a zero register). gas/testsuite/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * gas/aarch64/alias-2.d: New. * gas/aarch64/alias-2.s: New. include/opcode/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64.h (aarch64_op): Add OP_BFC. opcodes/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64-asm-2.c: Regenerate. * aarch64-asm.c (convert_bfc_to_bfm): New.

2015-11-27[AArch64] Let aliased instructions be their preferred form.Matthew Wahab5-2/+202
Although the AArch64 backend supports aliased instructions, the aliasing forms are always preferred over the real instruction. This makes it awkward to handle instructions which have aliases but which are their own preferred form. This patch includes the instruction being aliased in the list of alternatives which is searched when considering which form to use. opcodes/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64-asm-2.c: Regenerate. * aarch64-dis-2.c: Regenerate. * aarch64-dis.c: Weaken assert. * aarch64-gen.c: Include the instruction in the list of its possible aliases.

gdb.cp/annota2.exp Hi, I see one fail on aarch64-linux testing, FAIL: gdb.cp/annota2.exp: watch triggered on a.x (timeout) because GDB prints two frames-invalid annotation but the test expects only one. next^M ^M ^Z^Zpost-prompt^M ^M ^Z^Zstarting^M ^M ^Z^Zframes-invalid^M ^M ^Z^Zframes-invalid^M ^M Note I also see the fail on Debian-s390x-m64 too. https://sourceware.org/ml/gdb-testers/2015-q4/msg07291.html The test shouldn't only expect one frames-invalid annotation, because there can be multiple times of stop/resume before the user visible stop. Ulrich did something similar before https://www.sourceware.org/ml/gdb-patches/2009-06/msg00118.html This patch only changes ${frames_invalid} to \(${frames_invalid}\)* in the regexp pattern.

ARMv8.2 adds optional support for 16-bit operations to the FP and Adv.SIMD instructions. This patch adds a feature macro for this support with a new command line option "+fp16" to enable/disable it. Although the command line option is added as an architecture extension, it only affects instructions available with when +fp or +simd is enabled. If +fp16 is specified then it will also enable +fp.

I couldn't find a test that verified the thread name functionality, so I created a new one. A target board can define gdb,no_thread_names if it doesn't support thread names and wants to skip the tests that uses them. This test has been made with Linux in mind.

Since this code path returns a string owned by the target (we don't know how it's allocated, could be a static read-only string), it's safer if we return a constant string.

2015-11-24Linux: dump the signalled thread firstPedro Alves2-63/+75
... like the kernel does. gcore-thread.exp has a check to make sure the signalled thread is the current thread after loading the core back, but that just works by accident, because the signalled thread happened to be the last thread on the thread list, and gdb currently iterates over threads in reverse order. So this fixes gcore-thread.exp once we start walking threads in ascending number. gdb/ChangeLog: 2015-11-24 Pedro Alves <palves@redhat.com> * linux-tdep.c (find_stop_signal): Delete. (struct linux_corefile_thread_data) <pid>: Remove field. (linux_corefile_thread_callback): Rename to ... (linux_corefile_thread): ... this. Now takes a struct linux_corefile_thread_data pointer rather than a void pointer. Remove thread state and thread pid checks. (linux_make_corefile_notes): Prefer dumping the signalled thread first. Use ALL_NON_EXITED_THREADS instead of iterate_over_threads.
