2016-04-03cleanup FLT_CHARS and EXP_CHARSTrevor Saunders8-16/+17
Providing declarations in tc.h points out that alpha wasn't properly marking FLT_CHARS as const. We can also get rid of the confusing redefinition of X_CHARS to mmix_x_chars. Finally we can get rid of some now redundant declarations of these constants. gas/ChangeLog: 2016-04-03 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * config/tc-alpha.c: Const qualify FLT_CHARS. * config/atof-ieee.c: Remove declarations of FLT_CHARS and EXP_CHARS. * config/tc-cris.h: Likewise. * expr.c: Likewise. * config/tc-mmix.c (md_atof): Adjust comment. * config/tc-mmix.h: Stop defining FLT_CHARS and EXP_CHARS as macros. * tc.h: Declare FLT_CHARS and EXP_CHARS.

2016-04-01gdb: allow enumeration constants as second operand of BINOP_REPEATArtemiy Volkov4-1/+18
This patch adds support for TYPE_CODE_ENUM values to be supplied as right-hand side operand of the BINOP_REPEAT (@) operator. The following should now work: enum { sz = 17 }; int main () { int arr[sz + 1] = { 0 }; return 0; /* line 9 here */ } (gdb) b 9 (gdb) r (gdb) p arr@sz $1 = {0 <repeats 17 times>} (gdb) A couple of tests is also included in this patch to demonstrate that it is working as intended. gdb/Changelog: 2016-04-01 Artemiy Volkov <artemiyv@acm.org> PR gdb/19820 * eval.c (evaluate_subexp_standard): Allow TYPE_CODE_ENUM to be the type of BINOP_REPEAT's second operand. gdb/testsuite/Changelog: 2016-04-01 Artemiy Volkov <artemiyv@acm.org> PR gdb/19820 * gdb.base/printcmds.exp: Add artificial arrays tests.

2016-04-01PR19886, --as-needed regressionAlan Modra2-6/+27
This isn't perfect in checking whether libraries will be loaded since elf_link_add_object_symbols doesn't recurse down DT_NEEDED links. (That happens later in ld/emultempl/elf32.em after_open.) So in effect this recursive check really only looks one level down the DT_NEEDED tree. Which is enough for the most common case, and libc.so/ld.so in particular.

2016-03-31Fix PR gdb/19858: GDB doesn't register the JIT libraries on attachYichao Yu2-2/+20
Ref: https://sourceware.org/ml/gdb/2016-03/msg00023.html GDB currently fails to fetch the list of already-registered JIT modules on attach. Nothing is calling jit_inferior_init, which is what is responsible for walking the JIT object list at init time. Despite the misleading naming, jit_inferior_created_hook -> jit_inferior_init is only called when the inferior execs. This regressed with the fix for PR gdb/13431 (03bef283c2d3): https://sourceware.org/ml/gdb-patches/2012-02/msg00023.html which removed the inferior_created (jit_inferior_created_observer) observer. Adding an inferior_created observer back fixes the issue. In turn, this exposes a bug in jit_breakpoint_re_set_internal as well, which is returning the wrong result when we already have the breakpoint at the right address. gdb/ChangeLog: 2016-03-31 Yichao Yu <yyc1992@gmail.com> PR gdb/19858 * jit.c (jit_breakpoint_re_set_internal): Return 0 if we already got the breakpoint at the right address.

2016-03-31IPA: Add alloc_jump_pad_buffer target hook.Marcin Kościelnicki7-19/+194
Targets may have various requirements on the required location of the jump pad area. Currently IPA allocates it at the lowest possible address, so that it is reachable by branches from the executable. However, this fails on powerpc, which has executable link address (0x10000000) much larger than branch reach (+/- 32MiB). This makes jump pad buffer allocation a target hook instead. The current implementations are as follows: - i386 and s390: Branches can reach anywhere, so just mmap it. This avoids the linear search dance. - x86_64: Branches have +/-2GiB of reach, and executable is loaded low, so just call mmap with MAP_32BIT. Likewise avoids the linear search. - aarch64: Branches have +-128MiB of reach, executable loaded at 4MiB. Do a linear search from 4MiB-size downwards to page_size. - s390x: Branches have +-4GiB of reach, executable loaded at 2GiB. Do like on aarch64. gdb/gdbserver/ChangeLog: * linux-aarch64-ipa.c: Add <sys/mman.h> and <sys/auxv.h> includes. (alloc_jump_pad_buffer): New function. * linux-amd64-ipa.c: Add <sys/mman.h> include.

2016-03-31make xtensa_section_rename () take const char *Trevor Saunders3-4/+11
Xtensa uses it in several macros passing it a literal string, so its convenient for the argument type to be const char *. However some of the code in symbols.c seems to assume tc_canonicalize_symbol_name () will return a non const pointer, and some other target's implementations even modify the argument, so it seems best to return a char * which means casting away const on the argument when we return it instead of another string. gas/ChangeLog: 2016-03-31 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * config/tc-xtensa.c (struct rename_section_struct): Make old_name const.

2016-03-31tc-i960.c: add some casts when assigning literals to args[i]Trevor Saunders2-8/+13
parse_ldconst () takes a char ** as a in / out argument, and sometimes points args[0] to a constant string. Then in some cases after parse_ldconst () returns md_assemble () twiddles the contents of arg[0]. So it seems like it would take some work to avoid these casts, and its not really clear that work is worth it. gas/ChangeLog: 2016-03-31 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * config/tc-i960.c (parse_ldconst): Cast to char * when assigning to args[0].
2016-03-31cast the arg to md_assemble () to char *Trevor Saunders3-9/+18
For these targets its not clear how md_assemble can usefully be split up so that part can take const char *. There is also a fair number of targets that need md_assemble () to take a char *, so we can't easily make the argument const. So since there isn't many callers it seems easiest to just add a couple of casts. gas/ChangeLog: 2016-03-31 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * config/tc-m32c.c (m32c_md_end): cast the argument to md_assemble to char *.

2016-03-31work around get_symbol_name () in sparc and ia64Trevor Saunders3-3/+12
get_symbol_name () returns a char * in a out arg, which means we need to cast to assign a literal to the variable passed to get_symbol_name (). It seems like better APIs than get_symbol_name () could be provided, but that seems like a fair amount of work so just casting seems to be the betterthing to do for now. gas/ChangeLog: 2016-03-31 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * config/tc-ia64.c (md_assemble): Add temporary variable to pass to get_symbol_name (). * config/tc-sparc.c (s_register): Cast a literal to char * in assignment.
2016-03-31cast literal to char * when assigning to input_line_ptrTrevor Saunders6-9/+18
various places either directly or indirectly set input_line_pointer to point at a literal. Currently lots of places modify the string input_line_pointer points at, so making it const isn't easy. Since most if not all of these places assign to input_line_pointer to parse an expression it would probably be best to add ways to generate and deal with expressions that doesn't involve parsing strings, but for now adding some casts seems easiest. gas/ChangeLog: 2016-03-31 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * config/tc-i960.c (parse_expr): Cast to char * when assigning to input_line_pointer. * config/tc-m32r.c (expand_debug_syms): Likewise. * config/tc-msp430.c (msp430_dstoperand): Likewise. * config/tc-z80.c (md_begin): Likewise. * stabs.c (stabs_generate_asm_func): Likewise.

2016-03-30Don't override definition a shared object by one in a later shared object.Cary Coutant2-0/+13
In PR 16979, a reference to malloc is being resolved to an unversioned reference in libmalloc.so. When linked with --as-needed, however, the dynamic table does not list libmalloc.so as a DT_NEEDED library. If we have a reference to an unversioned symbol in a shared object, and we later see a versioned definition in another shared object, we were overriding the first definition with the second in the process of defining the default version. As a result, we no longer think that the first shared object was actually needed to resolve any symbols, and we don't list it as a DT_NEEDED library. This patch fixes the problem by treating the two definitions as separate symbols, so the second definition does not override the first. 2016-03-30 Cary Coutant <ccoutant@gmail.com> gold/ PR gold/16979 * symtab.cc (Symbol_table::define_default_version): Check for case where symbols are both in different shared objects.

2016-03-30gdbserver/IPA: Export some functions via global function pointers.Marcin Kościelnicki7-28/+103
On powerpc64, qSymbol for a function returns the function code address, and not the descriptor address. Since we emit code calling gdb_collect and some other functions, we need the descriptor (no way to know the proper TOC address without it). To get the descriptor address, make global function pointer variables in the IPA pointing to the relevant functions and read them instead of asking for them directly via qSymbol. gdb/gdbserver/ChangeLog: * linux-aarch64-ipa.c: Rename gdb_agent_get_raw_reg to get_raw_reg. * linux-amd64-ipa.c: Likewise. * linux-i386-ipa.c: Likewise. * linux-s390-ipa.c: Likewise. * tracepoint.c: IPA-export gdb_collect_ptr instead of gdb_collect, ditto for get_raw_reg_ptr, get_trace_state_variable_value_ptr, set_trace_state_variable_value_ptr.

2016-03-30Add arm epilogue unwinderYao Qi2-0/+116
Nowadays, GDB can't unwind successfully from epilogue on arm, (gdb) bt #0 0x76ff65a2 in shr1 () from /home/yao/Source/gnu/build/gdb/testsuite/gdb.reverse/shr1.sl #1 0x0000869e in main () at /home/yao/Source/gnu/build/gdb/testsuite/../../../binutils-gdb/gdb/testsuite/gdb.reverse/solib-reverse.c:34 Backtrace stopped: previous frame inner to this frame (corrupt stack?)

It analyzes the prologue and get the offsets of saved registers to SP. However, in epilogue, the SP has been restored, prologue unwinder gets the registers from the wrong address, and even the frame id is wrong. In reverse debugging, this case (program stops at the last instruction of function) happens quite frequently due to the reverse execution. There are many test fails due to missing epilogue unwinder. This adds epilogue unwinder, but the frame cache is still get by prologue unwinder except that SP is fixed up separately, because SP is restored in epilogue. This patch fixes many fails in solib-precsave.exp, and solib-reverse.exp. gdb: 2016-03-30 Yao Qi <yao.qi@linaro.org> * arm-tdep.c: (arm_make_epilogue_frame_cache): New function.

This patch is to refactor arm_stack_frame_destroyed_p, so that the code can be used in both arm_stack_frame_destroyed_p and arm epilogue unwinder I am going to add in the next patch. In fact, the code is the same in two places, but checking whether it is thumb mode is slightly different. arm_stack_frame_destroyed_p uses arm_pc_is_thumb, and epilogue unwinder should use arm_frame_is_thumb. gdb: 2016-03-30 Yao Qi <yao.qi@linaro.org> * arm-tdep.c (arm_stack_frame_destroyed_p): Rename it ...

2016-03-30Simplify gdb.reverse/until-reverse.cYao Qi4-9/+17
Nowadays, functions fprintf, printf and malloc are executed in gdb.reverse/until-reverse.c, so that it takes much time to record instructions inside them. This may cause timeout, and we had several fixes to bump the timeout, https://sourceware.org/ml/gdb-patches/2012-02/msg00038.html https://sourceware.org/ml/gdb-patches/2015-08/msg00186.html also I still see this on arm-linux, continue Continuing. Do you want to auto delete previous execution log entries when record/replay buffer becomes full (record full stop-at-limit)?([y] or n) n Process record: stopped by user.

(gdb) FAIL: gdb.reverse/until-precsave.exp: run to end of main (got interactive prompt) however, I can't figure out how these functions (fprintf, printf and malloc) are related to the test itself. marker1 is a function from shared library too so we don't need these complicated libc functions at all. IMO, recording the instructions in these libc functions has nothing to do with the test itself except slow down the test. This patch is to remove the usage of fprintf and printf, and also move malloc to a dead code path. gdb/testsuite: 2016-03-30 Yao Qi <yao.qi@linaro.org> * gdb.reverse/until-precsave.exp: Match function name only. * gdb.reverse/until-reverse.c (main): Don't call fprintf nor printf.
