2016-11-08Use ui_file_as_string throughout morePedro Alves31-614/+607
This replaces most of the remaining ui_file_xstrdup calls with ui_file_as_string calls. Whenever a call was replaced, that led to a cascade of other necessary adjustments throughout, to make the code use std::string instead of raw pointers. And then whenever I added a std::string as member of a struct, I needed to adjust allocation/destruction of said struct to use new/delete instead of xmalloc/xfree. The stopping point was once gdb built again. These doesn't seem to be a way to reasonably split this out further. Maybe-not-obvious changes: - demangle_for_lookup returns a cleanup today. To get rid of that, and avoid unnecessary string dupping/copying, this introduces a demangle_result_storage type that the caller instantiates and passes to demangle_for_lookup. - Many methods returned a "char *" to indicate that the caller owns the memory and must free it. Those are switched to return a std::string instead. Methods that return a "view" into some internal string return a "const char *" instead. I.e., we only copy/allocate when necessary. gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_name_for_lookup, type_as_string): Use and return std::string.

2016-11-08Use ui_file_as_string in gdb/compile/Pedro Alves8-86/+122
Using ui_file_as_string would imply changing a few prototypes to pass around source and object file names as std::string. Instead of that, wrap those two in a new class. This ends up eliminating a small wrinkle: get_new_file_names and compile_object_load have swapped parameters.

2016-11-08Clean up tracepoint.h/c:collection_listPedro Alves4-261/+300
Noticed we could do this while working on the expression_up change. The main goal here was getting rid of the encode_actions_and_make_cleanup / do_clear_collection_list cleanups. While at it, uncrustify the code: - Make collection_list a C++ class, with data members private (and thus renamed m_...). - Make related functions be member methods. - Use std::vector instead of an open coding a vector implementation. - Use std::sort instead of qsort. - Rename the "list" member of collection_list, which is an incredibly obfuscating name. - Rename a couple other things here and there for clarify. - Use "bool" more. gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * mi/mi-main.c (print_variable_or_computed): Constify 'expression' parameter.

2016-11-08Introduce ui_file_as_stringPedro Alves3-0/+35
ui_file_as_string is a variant of ui_file_xstrdup that returns a std::string instead of a xmalloc'ed char *.

Following patches will make use of this. gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * ui-file.c (do_ui_file_as_string, ui_file_as_string): New functions. * ui-file.h: Include <string>.

2016-11-08'struct expression *' -> gdb::unique_xmalloc_ptr<expression>Pedro Alves23-309/+257
This patch makes parse_expression and friends return a unique_ptr instead of raw pointer [1]: typedef gdb::unique_malloc_ptr<expression> expression_up; and then adjusts the codebase throughout to stop using cleanups to manage lifetime of expression pointers. Whenever I found a structure owning an expression pointer, I made it store a unique_ptr instead of a raw pointer, which then requires using new/delete of the holding structure, instead of XNEW/xfree. [1] - I'd like to set the rule that types named with an "_up" suffix are unique_ptr typedefs. Note I used gdb::unique_xmalloc_ptr instead of gdb::unique_ptr, simply because we still use xmalloc instead of new to allocate expression objects. Once that's changed, all we need to do is change the expression_up typedef and the smart pointer will then call delete instead of xfree. gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_read_renaming_var_value): Use expression_up.

2016-11-08breakpoint.c:commands_command_1 constification and cleanupPedro Alves3-26/+28
This is constification needed for next patch. Adjust commands_command_1 to use std::string too because the "arg" parameter is currently overwritten and then passed to make_cleanup. The constification alone would trigger a compile error in the make_cleanup call otherwise (passing const char * to void * parameter).

2016-11-08Check for truncated registers in process_g_packetLionel Flandrin2-3/+22
While investigating an unrelated issue in remote.c I noticed that the bound checking for 'g' packets was bogus: The previous code would only check that the first byte of the register was within bounds before passing the buffer to regcache_raw_supply. If it turned out that the register in the 'g' packet was incomplete then regcache_raw_supply would proceed to memcpy out-of-bounds. Since the buffer is allocated with alloca it's relatively unlikely to crash (you just end up dumping gdb's stack into the cache) but it's still a bit messy. I changed this logic to check for truncated registers and raise an error if one is encountered. Hopefully it should make debugging remote stubs a bit easier. gdb/ChangeLog: 2016-11-08 Lionel Flandrin <lionel@svkt.org> * remote.c (process_g_packet): Detect truncated registers in 'g' packets and raise an error.

2016-11-03Remove GDBARCH_BREAKPOINT_MANIPULATION and SET_GDBARCH_BREAKPOINT_MANIPULATIONYao Qi45-141/+384
Both of them are used in conversion. We can remove them since the conversion is done. There are many architectures only have one breakpoint instruction, so their gdbarch methods breakpoint_kind_from_pc and sw_breakpoint_from_kind look very similar. Instead of macro, we use template "template <size_t, const gdb_byte *> struct bp_manipulation" for these architectures. In order to use template, I also change breakpoint instruction of type "static const gdb_byte[]" to "constexpr gdb_byte[]", and rename them to ARCH_break_insn. gdb: 2016-11-03 Yao Qi <yao.qi@linaro.org> Pedro Alves <palves@redhat.com> * aarch64-tdep.c (aarch64_default_breakpoint): Change it to constexpr.

2016-11-03New gdbarch methods breakpoint_kind_from_pc and sw_breakpoint_from_kindYao Qi22-52/+238
This patch adds two gdbarch methods breakpoint_kind_from_pc and sw_breakpoint_from_kind, and uses target_info.placed_size as "kind" of the breakpoint. This patch updates the usages of target_info.placed_size. The "kind" of a breakpoint is determined by gdbarch rather than target, so we have gdbarch method breakpoint_kind_from_pc, and we should set target_info.placed_size out of each implementation of target to_insert_breakpoint. In this way, each target doesn't have to set target_info.placed_size any more. This patch also sets target_info.placed_address before target_insert_breakpoint too, so that target to_insert_breakpoint can use it, see record_full_insert_breakpoint. Before we call target_insert_breakpoint, we set target_info.placed_address and target_info.placed_size like this, CORE_ADDR addr = bl->target_info.reqstd_address; bl->target_info.placed_size = gdbarch_breakpoint_kind_from_pc (bl->gdbarch, &addr); bl->target_info.placed_address = addr; return target_insert_breakpoint (bl->gdbarch, &bl->target_info); target_insert_breakpoint may fail, but it doesn't matter to the "kind" and "placed_address" of a breakpoint. They should be determined by gdbarch. gdb: 2016-11-03 Yao Qi <yao.qi@linaro.org> * arch-utils.h (GDBARCH_BREAKPOINT_MANIPULATION): Define breakpoint_kind_from_pc and sw_breakpoint_from_kind.
