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 ... (arm_stack_frame_destroyed_p_1): ... here. Don't call arm_pc_is_thumb. (arm_stack_frame_destroyed_p): Call thumb_stack_frame_destroyed_p and arm_stack_frame_destroyed_p_1.
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. Program stopped. 0xf77021e6 in __linkin_atfork (newp=0xf7751748 <atfork_mem>) at ../nptl/sysdeps/unix/sysv/linux/register-atfork.c:117 117 ../nptl/sysdeps/unix/sysv/linux/register-atfork.c: No such file or directory. (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.

2016-03-24gas: sparc: allow ASR registers in the 0..31 range in V9 and laterJose E. Marchesi2-16/+21
In the SPARC V9 (and later) versions of the SPARC specification, the section C.1.1 "Register Names" specifies that: "asr_reg. An asr_reg is an Ancillary State Register name. It may have one of the following values: %asr16-%asr31" The rationale of having this restriction was that the registers from 16 to 31 are reserved to implementations, and are therefore "non-V9". It also assumes that the existing ASR registers in the range 0..31 will have their own names such as %y, that can be used to access such registers. However, this is problematic. When a new ASR register is introduced, such as %mcdper a.k.a. %asr14, it is useful to be able to use %asr14 in order to not depend on the latest version of the assembler. The Solaris assembler is lax and allows to assembly instructions referring to %asr0 to %asr31. This patch makes the GNU assembler to mimic that behavior. gas/ChangeLog: 2016-03-24 Jose E. Marchesi <jose.marchesi@oracle.com> * config/tc-sparc.c (sparc_ip): Remove the V9 restriction on ASR registers to be in the 16..31 range.
2016-03-24sparc: reorder wr instructions in sparc_opcodes to fix diagnosticsJose E. Marchesi2-6/+11
This patch changes the location of several variants of the `wr' instruction in sparc_opcodes. This is to get the assembler to emit the right diagnostics when an invalid %asrN register is used in an instruction.
2016-03-24make microblaze build with -Wwrite-stringsTrevor Saunders2-4/+9
frag_var () assigns its last argument to frag::fr_opcode, and it turns out some targets modify the string that points to. However it appears niether the generic code or the microblaze code modifies what fr_opcode points to, so this code should be safe. So we unfortunately need to cast to char * when passing an argument to frag_var () but otherwise microblaze can itself point to these strings with const char *. gas/ChangeLog: 2016-03-24 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * config/tc-microblaze.c (md_assemble): Cast opc to char * when calling frag_var ().
