2016-03-31cast to char * when assigning to optargTrevor Saunders2-1/+5

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.

2016-03-30Refactor arm_stack_frame_destroyed_pYao Qi2-6/+20
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.

(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.

2016-03-30gdbserver: Handle 'v' packet while processing qSymbol.Marcin Kościelnicki6-23/+56
On powerpc64, qSymbol query may require gdb to read a function descriptor, sending a vFile packet to gdbserver. Thus, we need to handle 'v' packet in look_up_one_symbol. vFile replies may be quite long, and require reallocating own_buf. Since handle_v_requests assumes the buffer is the static global own_buf from server.c and reallocates it, we need to make own_buf global and use it from look_up_one_symbol instead of using our own auto variable. I've also done the same change in relocate_instruction, just in case. On gdb side, in remote_check_symbols, rs->buf may be clobbered by vFile handling, yet we need its contents for the reply (the symbol name is stored there). Allocate a new buffer instead. This broke fast tracepoints on powerpc64, due to errors in reading IPA symbols. gdb/ChangeLog: * remote.c (remote_check_symbols): Allocate own buffer for reply. gdbserver/ChangeLog: * remote-utils.c (look_up_one_symbol): Remove own_buf, handle 'v' packets.

2016-03-29gdbserver/s390: Add fast tracepoint support.Marcin Kościelnicki6-63/+1336
Fast tracepoints will only work on 6-byte intructions, and assume at least a z900 CPU. s390 also has 4-byte jump instructions, which also work on pre-z900, but their range is limitted to +-64kiB, which is not very useful (and wouldn't work at all with current jump pad allocation). There's a little problem with s390_relocate_instruction function: it converts BRAS/BRASL instructions to LARL of the return address + JG to the target address. On 31-bit, this sets the high bit of the target register to 0, while BRAS/BRASL would set it to 1. While this is not a problem when the result is only used to address memory, it could possibly break something that expects to compare such addresses for equality without first masking the bit off. In particular, I'm not sure whether leaving the return address high bit unset is ABI-compliant (could confuse some unwinder?). If that's a problem, it could be fixed by handling it in the jump pad (since at that point we can just modify the GPRs in the save area without having to worry about preserving CCs and only having that one GPR to work with - I'm not sure if it's even possible to set the high bit with such constraints). gdb/gdbserver/ChangeLog: PR 18377 * Makefile.in: Add s390 IPA files. * configure.srv: Build IPA for s390. * linux-s390-ipa.c: New file. * linux-s390-low.c: New includes - inttypes.h and linux-s390-tdesc.h.

2016-03-29make md_parse_option () take a const char *Trevor Saunders74-113/+194
This is mostly just adding const in many places, however there are a couple interesting things. We need to add casts in tc-s390.c and tc-cris.c because they have functions that assign to input_line_pointer an argument that sometimes comes from md_parse_option. Presumably this is safe because those targets never pass literals to md_parse_option (), but this code should probably be improved in the future. Also xtensa passes the argument to strtoll which is a rather odd function, it takes a const char * as argument and returns a pointer into that string as a char * through an out argument, but we can work around that by adding more variables. gas/ChangeLog: 2016-03-29 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * config/tc-aarch64.c (struct aarch64_long_option_table): Ad const qualifier. * config/tc-alpha.c (md_parse_option): Likewise. * config/tc-arc.c (md_parse_option): Likewise. * config/tc-arm.c (struct arm_long_option_table): Likewise.
