2017-06-20Use '::iterator' instead of '::const_iterator' on environ.c (and fix ↵Sergio Durigan Junior2-2/+7
breakage on early versions of libstdc++) Even though C++11 supports modifying containers using a const_iterator (e.g., calling the 'erase' method of a std::vector), early versions of libstdc++ did not implement that. Some of our buildslaves are using these versions (e.g., the AArch64 buildslave uses gcc 4.8.8), and my previous commit causes a breakage on them. The solution is simple: just use a normal iterator, without const. gdb/ChangeLog: 2017-06-20 Sergio Durigan Junior <sergiodj@redhat.com> * common/environ.c (gdb_environ::unset): Use '::iterator' instead of '::const_iterator'.
2017-06-20C++ify gdb/common/environ.cSergio Durigan Junior17-189/+376
As part of the preparation necessary for my upcoming task, I'd like to propose that we turn gdb_environ into a class. The approach taken here is simple: the class gdb_environ contains everything that is needed to manipulate the environment variables. These variables are stored in an std::vector<char *>, which can be converted to a 'char **' and passed as argument to functions that need it. The usage has not changed much. As per Pedro's suggestion, this class uses a static factory method initialization. This means that when an instance is created, it is initially empty. When needed, it has to be initialized using the static method 'from_host_environ'. As mentioned before, this is a preparation for an upcoming work that I will be posting in the next few weeks or so. For that work, I'll probably create another data structure that will contain all the environment variables that were set by the user using the 'set environment' command, because I'll need access to them. This will be much easier with the class-ification of gdb_environ. As noted, this has been regression-tested with the new version of environ.exp and no regressions were found. gdb/ChangeLog: 2017-06-20 Sergio Durigan Junior <sergiodj@redhat.com> * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add 'unittests/environ-selftests.c'.

2017-06-19.gdb_index writer: close the file before unlinking itPedro Alves2-1/+10
We should close the file before unlinking because on MS-Windows one cannot delete a file that is still open. I considered making 'gdb::unlinker::unlinker(const char *)' 'noexcept(true)' and then adding static_assert (noexcept (gdb::unlinker (filename.c_str ())), ""); but that doesn't really work because gdb::unlinker has a gdb_assert, which can throw a QUIT if/when the assertion fails.

2017-06-17gdb: Use -Werror when checking for (un)supported warning flagsSimon Marchi5-9/+19
In warning.m4, we pass all the warning flags one by one to the compiler to test if they are supported by this particular compiler. If the compiler exits with an error, we conclude that this warning flag is not supported and exclude it. This allows us to use warning flags without having to worry about which versions of which compilers support each flag. clang, by default, only emits a warning if an unknown flag is passed: warning: unknown warning option '-Wfoo' [-Wunknown-warning-option] The result is that we think that all the warning flags we use are supported by clang (they are not), and the compilation fails later when building with -Werror, since the aforementioned warning becomes an error. The fix is to also pass -Werror when probing for supported flags, then we'll correctly get an error when using an unknown warning, and we'll exclude it: error: unknown warning option '-Wfoo' [-Werror,-Wunknown-warning-option] I am not sure why there is a change in a random comment in gdbserver/configure, but I suppose it's a leftfover from a previous patch, so I included it. gdb/ChangeLog: * configure: Re-generate. * warning.m4: Pass -Werror to compiler when checking for supported warning flags. gdb/gdbserver/ChangeLog: * configure: Re-generate.

2017-06-16Rewrite __start and __stop symbol handlingAlan Modra59-234/+484
This arranges for __start and __stop symbols to be defined before garbage collection, for all target formats. That should allow the COFF and PE --gc-sections to keep a singleton orphan input section, a feature lost by 2017-06-13 commit cbd0eecf26. The fancier ELF treatment of keeping all input sections associated with a __start or __stop symbol, from 2015-10-23 commit 1cce69b9dc, is retained. .startof. and .sizeof. symbols are deliberately not defined before garbage collection, so these won't affect garbage collection of sections. The patch also ensures __start, __stop, .startof. and .sizeof. symbols are defined before target size_dynamic_sections is called, albeit with a preliminary value, so that target code doesn't need to cope with a symbol changing from undefined at size_dynamic_sections to defined at relocate_section. Also, a number of problems with the testcases have been fixed.

Enforce CPU model for disassembler via its options, if it was specified in XML target description, otherwise use default method of determining CPU implemented in disassembler - scanning ELF private header. The latter requires disassemble_info->section to be properly initialized. To make sure that info->section is set in all cases this patch partially reverts [1] for ARC: it reinstates arc_delayed_print_insn as a "print_insn" function for ARC, but now this function only sets disassemble_info->section and then calls default_print_insn to do the rest of the job. Support for CPU in disassembler options for ARC has been added in [2].

2017-06-15[AArch64] Allow COPY relocation eliminationJiong Wang9-47/+220
As discussed at the PR, this patch tries to avoid COPY relocation generation and propagate the original relocation into runtime if it was relocating on writable section. The ELIMINATE_COPY_RELOCS has been set to true and it's underlying infrastructure has been improved so that the COPY reloc elimination at least working on absoluate relocations (ABS64) on AArch64. BFD linker copy relocation elimination framwork requires the backend to always allocate dynrelocs for all those relocation types that are possible to introduce copy relocations. This is for adjust_dynamic_symbol hook to be able to get all symbol reference information. Should one symbol is referenced by more than one relocations, if there is any of them needs copy relocation then linker should generate it. bfd/ PR ld/21532 * elfnn-aarch64.c (ELIMINATE_COPY_RELOCS): Set to 1.
