2018-12-06PR c++/88136 - -Wdeprecated-copy false positivesJason Merrill9-18/+47
Deprecating the copy operations because the class has a user-provided destructor turns out to have too many false positives; this patch adjusts -Wdeprecated-copy to only deprecate if the other copy operation is user-provided. To get the earlier behavior, people can explicitly request it with -Wdeprecated-copy-dtor. gcc/c-family/ * c.opt (Wdeprecated-copy-dtor): New. (Wdeprecated-copy): Move to -Wextra. gcc/cp/ * class.c (classtype_has_depr_implicit_copy): Rename from classtype_has_user_copy_or_dtor. * method.c (lazily_declare_fn): Adjust. * decl2.c (cp_warn_deprecated_use): Refer to -Wdeprecated-copy-dtor if deprecation is due to a destructor.

2018-12-06asm inlineSegher Boessenkool21-15/+215
The Linux kernel people want a feature that makes GCC pretend some inline assembler code is tiny (while it would think it is huge), so that such code will be inlined essentially always instead of essentially never. This patch lets you say "asm inline" instead of just "asm", with the result that that inline assembler is always counted as minimum cost for inlining.

2018-12-06asm qualifiers (PR55681)Segher Boessenkool9-63/+152
PR55681 observes that currently only one qualifier is allowed for inline asm, so that e.g. "volatile asm" is allowed, "const asm" is also okay (with a warning), but "const volatile asm" gives an error. Also "goto" has to be last. This patch changes things so that only "asm-qualifiers" are allowed, that is "volatile" and "goto", in any combination, in any order, but without repetitions.

2018-12-05runtime: add precise stack scan supportIan Lance Taylor1-1/+1
This CL adds support of precise stack scan using stack maps to the runtime. The stack maps are generated by the compiler (if supported). Each safepoint is associated with a (real or dummy) landing pad, and its "type info" in the exception table is a pointer to the stack map. When a stack is scanned, the stack map is found by the stack unwinding code by inspecting the exception table (LSDA). For precise stack scan we need to unwind the stack. There are three cases: - If a goroutine is scanning its own stack, it can unwind the stack and scan the frames. - If a goroutine is scanning another, stopped, goroutine, it cannot directly unwind the target stack. We handle this by switching (runtime.gogo) to the target g, letting it unwind and scan the stack, and switch back. - If we are scanning a goroutine that is blocked in a syscall, we send a signal to the target goroutine's thread, and let the signal handler unwind and scan the stack. Extra care is needed as this races with enter/exit syscall. Currently this is only implemented on linux. Reviewed-on: https://go-review.googlesource.com/c/140518 From-SVN: r266832

As Jakub pointed out, if we narrow a plus, minus or mult operation based on the number of bits that consumers need, we have to convert a signed operation to an unsigned one in order to avoid new undefined behaviour. This patch does that and generalises vect_convert_input and vect_recog_over_widening_pattern to cope with the extra casts.

2018-12-05testsuite: turn down verbosity of "process-message"David Malcolm2-2/+8
When debugging a failing test, I typically invoke DejaGnu at verbosity level 2 (via RUNTESTFLAGS="-v -v dg.exp=something"), so that DejaGnu prints the command line used to invoke the compiler; specifically these two sites: target.exp "Invoking the compiler as " remote.exp "Executing on $hostname" which are both verbosity level 2. Unfortunately I run into an O(n^2) issue with logging from process-message: verbose "process-message:\n${dg-messages}" 2 where, as each message each processed, it emits the state of dg-messages, containing the new message and all messages so far, leading to exponentially-increasing output at level 2 as more test messages are added.

2018-12-05[PR85569] skip constexpr target_expr constructor dummy type conversionAlexandre Oliva4-2/+107
The testcase is the work-around testcase for the PR; even that had started failing. The problem was that, when unqualifying the type of a TARGET_EXPR, we'd create a variant of the type, then request the conversion of the TARGET_EXPR_INITIAL to that variant type. Though the types are different pointer-wise, they're the same_type_p, so the resulting modified expr compares cp_tree_equal to the original, which maybe_constant_value flags as an error. There's no reason to construct an alternate TARGET_EXPR or CONSTRUCTOR just because of an equivalent type, except for another spot that expected pointer equality that would no longer be satisfied.
