2015-10-29mdebugread.c: Address class -> address class indexPedro Alves2-20/+34
This fixes this error in C++ mode: /home/pedro/gdb/mygit/cxx-convertion/src/gdb/mdebugread.c:654:11: error: invalid conversion from ‘int’ to ‘address_class’ [-fpermissive] theclass = mdebug_register_index; ^ The "theclass" local is of type enum address_class, however, what it really holds is an address class index. Class index values by design match the address class values up until LOC_FINAL_VALUE, but extend beyond that, so it's not really right to store an address class index in an enum address_class. The fix is really the same making the 'theclass' local be of type int, but while we're at it, we get rid of the goto, and thus the local becomes the 'aclass_index' parameter in the new add_data_symbol function. gdb/ChangeLog: 2015-10-29 Pedro Alves <palves@redhat.com> * mdebugread.c (add_data_symbol): New function, factored out from ... (parse_symbol): ... here. Delete 'theclass' local.
2015-10-29Add a cast in jit_target_read_implSimon Marchi2-1/+6
We could change the signature of the function. However, it would require changing gdb_target_read in jit-reader.h, which is an exported interface. It's probably better to just add a cast in our code than to break other people's code. gdb/ChangeLog: * jit.c (jit_target_read_impl): Add cast.

2015-10-29Add cast to VEC_iteratePedro Alves2-1/+5
Fixes this in C++: ../../src/gdb/break-catch-sig.c: In function ‘int VEC_gdb_signal_type_iterate(const VEC_gdb_signal_type*, unsigned int, gdb_signal_type*)’: ../../src/gdb/common/vec.h:576:12: error: invalid conversion from ‘int’ to ‘gdb_signal_type {aka gdb_signal}’ [-fpermissive] *ptr = 0; \ ^ ../../src/gdb/common/vec.h:417:1: note: in expansion of macro ‘DEF_VEC_FUNC_P’ DEF_VEC_FUNC_P(T) \ ^ ../../src/gdb/break-catch-sig.c:37:1: note: in expansion of macro ‘DEF_VEC_I’ DEF_VEC_I (gdb_signal_type); ^ I actually carried a different fix in the C++ branch that removed this assignment and then adjusted all callers that depended on it. The thinking was that this is for the case where we're returning false, indicating end of iteration. But that results in a much larger and tricker patch; looking back it seems quite pointless. I looked at the history of GCC's C++ conversion and saw that they added this same cast to their version of vec.h, FWIW. (GCC's vec.h is completely different nowadays, having been converted to templates meanwhile.) gdb/ChangeLog: 2015-10-29 Pedro Alves <palves@redhat.com> * common/vec.h (DEF_VEC_FUNC_P) [iterate]: Cast 0 to type T.

2015-10-29gnu-v2-abi.c: Add castsPedro Alves2-2/+7
I looked at changing these is_destructor_name/is_constructor_name interfaces in order to detangle the boolean result from the ctor/dtor kind return, but then realized that this design goes all the way down to the libiberty demangler interfaces. E.g, include/demangle.h: ~~~ /* Return non-zero iff NAME is the mangled form of a constructor name in the G++ V3 ABI demangling style. Specifically, return an `enum gnu_v3_ctor_kinds' value indicating what kind of constructor it is. */ extern enum gnu_v3_ctor_kinds is_gnu_v3_mangled_ctor (const char *name); enum gnu_v3_dtor_kinds { gnu_v3_deleting_dtor = 1, gnu_v3_complete_object_dtor, gnu_v3_base_object_dtor, /* These are not part of the V3 ABI. Unified destructors are generated as a speed-for-space optimization when the -fdeclone-ctor-dtor option is used, and are always internal symbols. */ gnu_v3_unified_dtor, gnu_v3_object_dtor_group }; ~~~ libiberty/cp-demangle.c: ~~~ enum gnu_v3_ctor_kinds is_gnu_v3_mangled_ctor (const char *name) { enum gnu_v3_ctor_kinds ctor_kind; enum gnu_v3_dtor_kinds dtor_kind; if (! is_ctor_or_dtor (name, &ctor_kind, &dtor_kind)) return (enum gnu_v3_ctor_kinds) 0; return ctor_kind; } ~~~ etc. gdb/ChangeLog: 2015-10-29 Pedro Alves <palves@redhat.com> * gnu-v2-abi.c (gnuv2_is_destructor_name) (gnuv2_is_constructor_name): Add casts.

2015-10-29Don't assume break/continue inside a TRY block worksPedro Alves6-194/+261
In C++, this: try { break; } catch (..) {} is invalid. However, because our TRY/CATCH macros support it in C, the C++ version of those macros support it too. To catch such assumptions, this adds a (disabled) hack that maps TRY/CATCH to raw C++ try/catch. Then it goes through all instances that building on x86_64 GNU/Linux trips on, fixing them. This isn't strictly necessary yet, but I think it's nicer to try to keep the tree in a state where it's easier to eliminate the TRY/CATCH macros. gdb/ChangeLog: 2015-10-29 Pedro Alves <palves@redhat.com> * dwarf2-frame-tailcall.c (dwarf2_tailcall_sniffer_first): Don't assume that "break" breaks out of a TRY/CATCH. * python/py-framefilter.c (py_print_single_arg): Don't assume "continue" breaks out of a TRY/CATCH. * python/py-value.c (valpy_binop_throw): New function, factored out from ...

2015-10-28Pass noaliases_p to aarch64_decode_insnYao Qi6-8/+27
Nowadays aarch64_decode_insn is a public interface used by both opcodes and gdb. However, its behaviour relies on a global variable no_aliases, which isn't a good practise. On the other hand, In default, no_aliases is zero, but in GDB, we do want no alias when decoding instructions for prologue analysis (patches to be posted), so that we can handle both instructions "add" and "mov" (an alias of "add") as "add". The code in GDB can be simplified. This patch adds a new argument in aarch64_decode_insn, and pass no_aliases to it. In GDB side, always pass 1 to it. include/opcode: 2015-10-28 Yao Qi <yao.qi@linaro.org> * aarch64.h (aarch64_decode_insn): Update declaration. opcodes: 2015-10-28 Yao Qi <yao.qi@linaro.org> * aarch64-dis.c (aarch64_decode_insn): Add one argument noaliases_p.
