2018-03-08remote-stdio-gdbserver: Pass "target" to remote_exec to delete fileSimon Marchi2-1/+7
As described here https://sourceware.org/bugzilla/show_bug.cgi?id=22841 there seems to be situations where the remote-stdio-gdbserver board fails to delete the uploaded binary file. Passing "target" fixes the issue for Christian who reported the bug. I did not experience this problem, but passing "target" to remote_exec still works for me, so I'm fine with changing it. Any objection? gdb/testsuite/ChangeLog: PR gdb/22841 * boards/remote-stdio-gdbserver.exp (${board}_file): Pass "target" to remote_exec.
2018-03-08Don't redefine upload/download/file in gdbserver-baseSimon Marchi2-22/+6
Before patch Make native gdbserver boards no longer be "remote" (in DejaGnu terms) 739b3f1d8ff7072dcc66240c25b026c6433bda1a the local gdbserver boards (except native-extended-gdbserver...) were considered as remote by DejaGNU. To avoid DejaGNU trying to use ssh/scp to download the files to the target (which is actually local), the gdbserver-base.exp file defined some _download, _upload and _file board operations to override the default behavior, and instead just use local operations. The same patch also changed remote-stdio-gdbserver.exp to make it inherit from gdbserver-base.exp. Since then, this board (which is actually remote) uses the overrides with local file operations. As a result, files are never actually copied to the target. I think we can simply remove the overrides from gdbserver-base.exp. Because all boards should be properly considered local or remote by DejaGNU, it should by default use the right method for transferring files. gdb/testsuite/ChangeLog: PR gdb/22841 * boards/gdbserver-base.exp (${board}_file, ${board}_download, ${board}_upload): Remove.

2018-03-08x86: fold several AVX512VL templatesJan Beulich6-2058/+404
The differences between some of the register and memory forms of the same insn often don't really require the templates to be separate. For example, Disp8MemShift is simply irrelevant to register forms. Fold these as far as possible, and also fold register-only forms. Further folding is possible, but needs other prereq work done first. A note regarding EVEXDYN: This is intended to be used only when no other properties of the template would make is_evex_encoding() return true. In all "normal" cases I think it is preferable to omit this indicator, to keep the table half way readable.
2018-03-08x86: fold certain AVX512 rotate and shift templatesJan Beulich5-957/+151
Their memory forms were bogusly using VexLWP instead of VexNDD. Adjust VexNDD handling to cope with these, allowing their register and memory forms to be folded.
2018-03-08x86: fold VEX-encoded GFNI templatesJan Beulich3-86/+21
2018-03-08x86: fold a few AVX512F templatesJan Beulich3-240/+31
The differences between some of the register and memory forms of the same insn often don't really require the templates to be separate. For example, Disp8MemShift is simply irrelevant to register forms. Fold them as far as possible. Further folding is possible, but needs other prereq work done first.
2018-03-08x86: fold LWP templatesJan Beulich3-86/+20
Also drop the no longer necessary explicit Disp<N> from them.

2018-03-08x86: drop {X,Y,Z}MMWORD_MNEM_SUFFIXJan Beulich6-45/+39
They aren't really useful (anymore?): The conflicting operand size check isn't applicable to any insn validly using respective memory operand sizes (and if they're used wrongly, another error would result), and the logic in process_suffix() can be easily changed to work without them. While re-structuring conditionals in process_suffix() also drop the CMPXCHG8B special case in favor of a NoRex64 attribute in the opcode table.
2018-03-08x86: correct operand size match checks for BMI/BMI2 insnsJan Beulich5-7/+64
Some BMI/BMI2 insns allow their middle operands to be a memory one. In such a case, matching register types between operands 0 and 1 as well as 1 and 2 won't help - operands 0 and 2 also need to be checked.
2018-03-08x86: fold redundant expressions in process_suffix()Jan Beulich2-20/+18

2018-03-08x86: simplify result processing of cpu_flags_match()Jan Beulich2-24/+21
Make more obvious what the success and failure paths are, and in particular that what used to be at the "skip" label can't be reached by what used to be straight line code.
2018-03-08x86: add GFNI, VAES, and VPCLMUL checking to cpu_flags_match()Jan Beulich19-2/+177
Just like for the AVX/AES and AVX/PCLMUL combinations, AVX/GFN, AVX512F/GFNI, AVX512F/VAES, and AVX512F/PCLMUL need special handling to deal with the pair of required checks specified in the templates.
2018-03-08x86: change AVX512VL handling in cpu_flags_match()Jan Beulich2-11/+9
In order to add an AVX512F counterpart to the present AVX checking, it is better to move the AVX512VL check out of the conditional it's currently in.
2018-03-08x86: drop CPU_FLAGS_32BIT_MATCHJan Beulich2-5/+10
It has become a plain alias of CPU_FLAGS_ARCH_MATCH now.
2018-03-08x86: simplify AVX checks in cpu_flags_match()Jan Beulich2-22/+14
No caller cares about the specifics of CPU_FLAGS_{AES,AVX,PCLMUL}_MATCH, so drop those and fold the nested if()-s.

2018-03-08x86: drop bogus NoAVXJan Beulich3-14/+20
These are meaningful only for insns with CpuSSE* (and a few other Cpu*) attribute.
2018-03-08x86: avoid SSE check for LDMXCSR/STMXCSRJan Beulich3-4/+9
Neither touches any XMM register, so the check is pointless. It is imo even questionable whether in SSE2AVX mode the two should be converted to their AVX counterparts.
2018-03-08x86: extend SSE check to PCLMULQDQ, AES, and GFNI insnsJan Beulich16-126/+88
When aiming at not mixing SSE and AVX insns, these should be warned about the same way other non-AVX ones are treated.
2018-03-08x86: drop FloatDJan Beulich7-19745/+19755
It can be expressed by D, when making the consumer look at operand size to tell apart both uses.
2018-03-08x86/Intel: correct disassembly of fsub*/fdiv*Jan Beulich5-8/+728
fsub/fsubr/fsubp/fsubrp as well as fdiv/fdivr/fdivp/fdivrp disassembly should match (a) the Intel SDM and (b) respective input fed to gas (both of course with the exception of when we intentionally convert bogus insns, accompanied by a warning).
2018-03-08x86: adjust 4-XMM-register-group related warningJan Beulich4-30/+39
Drop "second": For one there's no other source register (the other source operand is in memory), and in Intel syntax such numbering would also be wrong. Take the opportunity and also - properly place declarations ahead of statements - use %u format for unsigned int arguments - fix indentation
2018-03-08x86: bogus VMOVD with 64-bit operands should only allow for registersJan Beulich7-12/+17
These templates exist solely to satisfy gcc's needs, and gcc only produces these with register operands.
2018-03-08x86: fold AVX vcvtpd2ps memory formsJan Beulich5-30/+50
This requires a change to ModR/M handling: Recording of displacement types must not discard operand size information. Change the respective code to alter only .disp<N>.

Oops, not tested well enough. -mpower9 sets all the PPC_OPCODE_POWERn for n <= 9. * config/tc-ppc.c (ppc_handle_align): Correct last patch. Really don't emit a group terminating nop for power9. Simplify cpu tests.
2018-03-08Remove unnecessary power9 group terminating nopAlan Modra2-10/+13
Power9 doesn't have a group terminating nop, so we may as well emit a normal nop for power9. Not that it matters a great deal, I believe ori 2,2,0 will be treated exactly as ori 0,0,0 by the hardware. * config/tc-ppc.c (ppc_handle_align): Don't emit a group terminating nop for power9.

2018-03-07Fix watching structs in C++Andreas Arnez5-2/+76
Some of the watchpoint logic depends on the fact that the head of the value chain represents the user-specified value to watch. Thus no additional values should be added to the value chain after that. However, if a watchpoint is defined for a C++ structure/class object, then run-time type information (RTTI) may be present. Thus, while constructing the value chain for the watchpoint, the dynamic type is fetched by gnuv3_rrti_type, which invokes value_addr, which then adds a new value to the head of the value chain. This new value represents the pointer to the structure instead of the structure itself. With such a "polluted" value chain the watchpoint logic does not recognize when the user intended to watch a struct, and can_use_hardware_watchpoint returns zero. Instead of a hardware watchpoint, a software watchpoint will then be set for no apparent reason. This is fixed by adding an early exit to gnuv3_rtti_type when the input value is not a dynamic class object. gdb/testsuite/ChangeLog: * gdb.cp/watch-cp.cc: New test. * gdb.cp/watch-cp.exp: New file. gdb/ChangeLog: * gnu-v3-abi.c (gnuv3_rtti_type): Add early exit if the given value is not a dynamic class object.

I noticed a few formatting buglets in rust-exp.y: A couple of lines were too long, and a couple of parser rules did not follow the same formatting as the rest of the code. I'm checking this in as obvious. Tested by rebuilding. 2018-03-06 Tom Tromey <tom@tromey.com> * rust-exp.y: Formatting fixes.

2018-03-06gdb/riscv: Remove partial target description supportAndrew Burgess2-37/+6
Some parts of the target description support were committed with the initial riscv patch. As target descriptions are not currently supported on riscv this commit removes the two pieces for code that relate to target description support. It is expected that target description support will be added in the future, at which point this, or similar code will be added back. gdb/ChangeLog: * riscv-tdep.c (riscv_register_name): Remove target description support. (riscv_gdbarch_init): Remove target description check.
2018-03-06gdb/riscv: Remove 'Contributed by....' commentsAndrew Burgess3-10/+6
The GDB coding standard states these lines should never have been added. gdb/ChangeLog: * riscv-tdep.c: Remove 'Contributed by ...' lines from header comment. * riscv-tdep.h: Likewise.
2018-03-06gdb/riscv: Remove use of pseudo registersAndrew Burgess2-25/+6
The code making use of pseudo registers was initially intended to support running 32-bit ABI files on 64-bit riscv targets. However, the implementation was incomplete, and broken. For now I've removed all reference to pseudo registers from the riscv target, we've not lost any functionality, and this cleans up failures in the selftests. Once the riscv target has matured a little we'll probably end up bringing back some of the use of pseudo registers in order to better support running 32-bit executables on a 64-bit target. gdb/ChangeLog: * riscv-tdep.c (riscv_pseudo_register_read): Delete. (riscv_pseudo_register_write): Delete. (riscv_gdbarch_init): Remove all use of pseudo registers.
2018-03-06btrace: Remove ui_out cleanupsSimon Marchi4-82/+35
This patch replaces the cleanups that close the list and tuple of the btrace instruction history output with ui_out_emit_tuple and ui_out_emit_list. This allows removing make_cleanup_ui_out_tuple_begin_end and make_cleanup_ui_out_list_begin_end. This patch (along with the previous ones in the series) was regtested on the buildbot. gdb/ChangeLog: * record-btrace.c (btrace_print_lines): Replace cleanup parameter with RAII equivalents. (btrace_insn_history): Replace cleanup with RAII equivalents. * ui-out.h (make_cleanup_ui_out_list_begin_end, make_cleanup_ui_out_tuple_begin_end): Remove. * ui-out.c (struct ui_out_end_cleanup_data, do_cleanup_end, make_cleanup_ui_out_end, make_cleanup_ui_out_tuple_begin_end, make_cleanup_ui_out_list_begin_end): Remove.
