This patch extends Tag_GNU_Power_ABI_FP to cover long double ABIs, makes the assembler warn about undefined tag values, and removes similar warnings from the linker. I think it is better to not warn in the linker about undefined tag values as future extensions to the tags then won't result in likely bogus warnings.

2016-09-23gdb: Replace operator new / operator new[]Pedro Alves6-4/+132
If xmalloc fails allocating memory, usually because something tried a huge allocation, like xmalloc(-1) or some such, GDB asks the user what to do: .../src/gdb/utils.c:1079: internal-error: virtual memory exhausted. A problem internal to GDB has been detected, further debugging may prove unreliable. Quit this debugging session? (y or n) If the user says "n", that throws a QUIT exception, which is caught by one of the multiple CATCH(RETURN_MASK_ALL) blocks somewhere up the stack. The default implementations of operator new / operator new[] call malloc directly, and on memory allocation failure throw std::bad_alloc. Currently, if that happens, since nothing catches it, the exception escapes out of main, and GDB aborts from unhandled exception. This patch replaces the default operator new variants with versions that, just like xmalloc: #1 - Raise an internal-error on memory allocation failure. #2 - Throw a QUIT gdb_exception, so that the exact same CATCH blocks continue handling memory allocation problems. A minor complication of #2 is that operator new can _only_ throw std::bad_alloc, or something that extends it: void* operator new (std::size_t size) throw (std::bad_alloc); That means that if we let a gdb QUIT exception escape from within operator new, the C++ runtime aborts due to unexpected exception thrown. So to bridge the gap, this patch adds a new gdb_quit_bad_alloc exception type that inherits both std::bad_alloc and gdb_exception, and throws _that_. If we decide that we should be catching memory allocation errors in fewer places than all the places we currently catch them (everywhere we use RETURN_MASK_ALL currently), then we could change operator new to throw plain std::bad_alloc then. But I'm considering such a change as separate matter from this one -- it'd make sense to do the same to xmalloc at the same time, for instance. Meanwhile, this allows using new/new[] instead of xmalloc/XNEW/etc. without losing the "virtual memory exhausted" internal-error safeguard.

In commit 6423214f (testsuite: Don't use expect_background to reap gdbserver), we override gdb_exit in lib/gdbserver-support.exp, so that we can close gdbserver first. However, we don't close gdbserver in mi_gdb_exit. This makes a problem in my aarch64 mulit-arch testing, in which I run some mi tests, mi-watch.exp for example, in different variations (aarch64 and arm), Schedule of variations: junor0-2 junor0-2-arm/-marm junor0-2-arm/-mthumb When the test is done in the first variation (aarch64), test case is recompiled for arm, but GDBserver with aarch64 program is still running. When the second variation is started, GDB loads arm program, but GDBserver still loads aarch64 program because the old GDBserver process is using it.

2016-09-21PR gdb/20604 - fix "quit" when an invalid expression is usedTom Tromey6-10/+65
This fixes PR gdb/20604. The bug here is that passing an invalid expression to "quit" -- e.g., "quit()" -- causes gdb to enter a non-functioning state. The immediate problem is that quit_force resets the terminal before evaluating the expression. However, it seemed to me that it doesn't really make sense to pass the quit_force argument to kill_or_detach (which passes it to to_detach), first because conflating the exit status for "quit" and the signal to pass when detaching doesn't make sense, and second because to_detach implementations generally only accept a constant here, while "quit" accepts an expression. So, I removed that. As an aside, I think the "detach SIGNO" functionality is not documented.

2016-09-21[AArch64] Print spaces after commas in addressesRichard Sandiford59-9712/+9783
I got an off-list request to make the AArch64 disassembler print spaces after commas in addresses. This patch does that. The same code is used to print operands in "did you mean" errors, so to keep things consistent, the patch also prints spaces between operands in those messages. opcodes/ * aarch64-opc.c (print_immediate_offset_address): Print spaces after commas in addresses.

2016-09-21[AArch64] Use "must" rather than "should" in error messagesRichard Sandiford8-83/+98
One of the review comments from the SVE series was that it would be better to use "must" rather than "should" in error messages. I think this patch fixes all cases in the AArch64 code. It also uses "must be" instead of "expected to be". opcodes/ * aarch64-opc.c (operand_general_constraint_met_p): Use "must be" rather than "should be" or "expected to be" in error messages. gas/ * config/tc-aarch64.c (output_operand_error_record): Use "must be" rather than "should be" or "expected to be" in error messages.

2016-09-21[AArch64] Add SVE condition codesRichard Sandiford19-98/+318
SVE defines new names for existing NZCV conditions, to reflect the result of instructions like PTEST. This patch adds support for these names. The patch also adds comments to the disassembly output to show the alternative names of a condition code. For example: cinv x0, x1, cc becomes: cinv x0, x1, cc // cc = lo, ul, last and: b.cc f0 <...> becomes: b.cc f0 <...> // b.lo, b.ul, b.last Doing this for the SVE names follows the practice recommended by the SVE specification and is definitely useful when reading SVE code. If the feeling is that it's too distracting elsewhere, we could add an option to turn it off. include/ * opcode/aarch64.h (aarch64_cond): Bump array size to 4. opcodes/ * aarch64-dis.c (remove_dot_suffix): New function, split out from... (print_mnemonic_name): ...here. (print_comment): New function. (print_aarch64_insn): Call it. * aarch64-opc.c (aarch64_conds): Add SVE names. (aarch64_print_operand): Print alternative condition names in a comment. gas/ * config/tc-aarch64.c (opcode_lookup): Search for the end of a condition name, rather than assuming that it will have exactly 2 characters. (parse_operands): Likewise. * testsuite/gas/aarch64/alias.d: Add new condition-code comments to the expected output. * testsuite/gas/aarch64/beq_1.d: Likewise. * testsuite/gas/aarch64/float-fp16.d: Likewise. * testsuite/gas/aarch64/int-insns.d: Likewise. * testsuite/gas/aarch64/no-aliases.d: Likewise. * testsuite/gas/aarch64/programmer-friendly.d: Likewise. * testsuite/gas/aarch64/reloc-insn.d: Likewise. * testsuite/gas/aarch64/b_c_1.d, testsuite/gas/aarch64/b_c_1.s: New test. ld/ * testsuite/ld-aarch64/emit-relocs-280.d: Match branch comments. * testsuite/ld-aarch64/weak-undefined.d: Likewise.
