2020-07-22libstdc++: Add static assertions to futures and promises [LWG 3458]Jonathan Wakely4-0/+115
LWG recently decided it should be ill-formed to instantiate std::future and std::shared_future for types that can't be returned from a function. This adds static assertions to enforce it (std::future already failed, but this makes the error more understandable). LWG 3466 extends that to std::promise. The actual constraint is that t.~T() is well-formed for the primary template, but rejecting arrays and functions as done for futures matches that condition. libstdc++-v3/ChangeLog: * include/std/future (future, shared_future, promise): Add static assertions to the primary template to reject array and function types. * testsuite/30_threads/future/requirements/lwg3458.cc: New test. * testsuite/30_threads/promise/requirements/lwg3466.cc: New test. * testsuite/30_threads/shared_future/requirements/lwg3458.cc: New test.

LE mode PR96236 shows a problem where we don't correctly store our 512-bit accumulators correctly in little-endian mode.

2020-07-22c++: structural_comptypes additionNathan Sidwell1-9/+15
I had to debug structural_comptypes, and its complex if conditions and tail calling of same_type_p made that hard. I'd hope we can turn the eqivalent of return boolean_fn () ? true : false; into a tail call of the boolean. We also were not dealing with TYPEOF_TYPE. gcc/cp/ * typeck.c (structural_comptypes): [DECLTYPE_TYPE] break apart complex if. [UNDERLYING_TYPE]: Use an if. [TYPEOF_TYPE]: New.
2020-07-22c++: More cleanups for modern C++Nathan Sidwell3-58/+39
Here are some more places where we can declare variables at the assignment point, rather than use C89.

2020-07-22c++: Shrink lambda-exprNathan Sidwell1-2/+2
I noticed the default capture mode and the discriminator both used ints. That seems excessive. This shrinks them to 8 bits and 16 bits respectively. I suppose the discriminator could use the remaining 24 bits of an int allocation unit, if we're worried about more that 64K lambdas per function. I know, users are strange :) On a 64 bit system this saves 64 bits, because we also had 32 bits of padding added. gcc/cp/ * cp-tree.h (struct tree_lambda_expr): Shrink default_capture_mode & discriminator.

2020-07-22c++: mangling cleanupsNathan Sidwell1-49/+26
I noticed the mangler's handling of templates could be simplified. We know template_info is non-null, which is sufficiently boolean -- no need for an explicit bool return. also some of the internals of template_args_equal had crept into find_substitution. Let's not do that. gcc/cp/ * mangle.c (decl_is_template_id): Rename to ... (maybe_template_info): ... here. Return the template info, rather than use a pointer. Adjust all callers. (find_substitution): Use template_args_equal, rather than local check.

2020-07-22expr: Allow scalar_int_mode target mode when converting a constantJozef Lawrynowicz1-2/+2
is_int_mode does not allow MODE_PARTIAL_INT modes, so convert_modes was not allowing a constant value to be converted to a MODE_PARTIAL_INT for use as operand 2 in patterns such as ashlpsi3. The constant had to be copied into a register before it could be used, but now can be used directly as an operand without any copying. gcc/ChangeLog: * expr.c (convert_modes): Allow a constant integer to be converted to any scalar int mode.

2020-07-22Generation of adjusted ldp/stp for vector typesPrzemyslaw Wirkus10-6/+151
Introduce simple peephole2 optimization which substitutes a sequence of four consecutive load or store (LDR, STR) instructions with two load or store pair (LDP, STP) instructions for 2 element supported vector modes (V2SI, V2SF, V2DI, and V2DF).

Regular ELF label definitions for this test-case, matched by the regexps, e.g.: /* { dg-final { scan-assembler-times {(?n)^_*bar[.$_]constprop[.$_]0:} 1 } } */ typically look like this: bar_constprop.0: For MMIX, they look like this: bar_constprop::0 IS @ I think it's better to just skip the test for MMIX than further uglifying the matching regexps, since the test is IIUC general enough that nothing in the target port can reasonably make a difference: it passes for all targets or fail for all targets. gcc/testsuite: * gcc.dg/independent-cloneids-1.c: Skip for mmix. flag_stack_usage_info.

2020-07-21mmix: support -fstack-usageHans-Peter Nilsson1-0/+16
MMIX has two stacks; the regular one using register $254 as a convention and the register-stack, pushed and popped by call instructions (usually). The decision to only report the stack usage of the regular stack (and not of the register stack) may be updated, perhaps the sum is better. This initial decision is helped a little bit by the order of passes: the size of the register-stack is calculated only later (in the machine-dependent reorg pass), long after finalization of the stack-usage info (in the prologue/epilogue pass). No regressions for mmix-knuth-mmixware (but a whole lot more PASSes), committed. gcc: * config/mmix/mmix.c (mmix_expand_prologue): Calculate the total allocated size and set current_function_static_stack_size, if flag_stack_usage_info.
2020-07-20libstdc++: Add std::from_chars for floating-point typesJonathan Wakely17-5/+1083
This adds the missing std::from_chars overloads for floating-point types, as required for C++17 conformance. The implementation is a hack and not intended to be used in the long term. Rather than parsing the string directly, this determines the initial portion of the string that matches the pattern determined by the chars_format parameter, then creates a NTBS to be parsed by strtod (or strtold or strtof). Because creating a NTBS requires allocating memory, but std::from_chars is noexcept, we need to be careful to minimise allocation. Even after being careful, allocation failure is still possible, and so a non-conforming std::no_more_memory error code might be returned. Because strtod et al depend on the current locale, but std::from_chars does not, we change the current thread's locale to "C" using newlocale and uselocale before calling strtod, and restore it afterwards. Because strtod doesn't have the equivalent of a std::chars_format parameter, it has to examine the input to determine the format in use, even though the std::from_chars code has already parsed it once (or twice for large input strings!) By replacing the use of strtod we could avoid allocation, avoid changing locale, and use optimised code paths specific to each std::chars_format case. We would also get more portable behaviour, rather than depending on the presence of uselocale, and on any bugs or quirks of the target libc's strtod. Replacing strtod is a project for a later date. libstdc++-v3/ChangeLog: * acinclude.m4 (libtool_VERSION): Bump version. * config.h.in: Regenerate. * config/abi/pre/gnu.ver: Add GLIBCXX_3.4.29 version and new exports. * config/os/gnu-linux/ldbl-extra.ver: Add _GLIBCXX_LDBL_3.4.29 version and new export. * configure: Regenerate. * configure.ac: Check for <xlocale.h> and uselocale. * crossconfig.m4: Add macro or checks for uselocale. * include/std/charconv (from_chars): Declare overloads for float, double, and long double. * src/c++17/Makefile.am: Add new file. * src/c++17/Makefile.in: Regenerate. * src/c++17/floating_from_chars.cc: New file.

2020-07-20c++: Pseudo-destructor ends object lifetime.Jason Merrill3-9/+31
P0593R6 is mostly about a new object model whereby malloc and the like are treated as implicitly starting the lifetime of whatever trivial types are necessary to give the program well-defined semantics; that seems only relevant to TBAA, and is not implemented here. The paper also specifies that a pseudo-destructor call (a destructor call for a non-class type) ends the lifetime of the object like a destructor call for an object of class type, even though it doesn't call a destructor; this patch implements that change. The paper was voted as a DR, so I'm applying this change to all standard levels. Like class end-of-life clobbers, it is controlled by -flifetime-dse. gcc/cp/ChangeLog: * pt.c (type_dependent_expression_p): A pseudo-dtor can be dependent. * semantics.c (finish_call_expr): Use build_trivial_dtor_call for pseudo-destructor. (finish_pseudo_destructor_expr): Leave type NULL for dependent arg. gcc/testsuite/ChangeLog: * g++.dg/opt/flifetime-dse7.C: New test.
2020-07-20c++: Allow subobject references in C++20.Jason Merrill10-14/+126
The last new thing allowed by P1907R1: subobject addresses as template arguments. The ABI group has discussed mangling for this; there has been some talk of a compressed subobject mangling, but it hasn't been finalized, so for now I'm using normal expression mangling. In order for two array subobject references to compare as equal template arguments, the offsets need to have the same type, so I convert them to always be the same type, currently ptrdiff_t. Base class conversions are represented as a cast to reference type, only if necessary to resolve an ambiguity. This patch also updates the value of __cpp_nontype_template_args, since the paper is fully implemented. gcc/cp/ChangeLog: * mangle.c (write_base_ref): New. (write_expression): Use it for base field COMPONENT_REFs. * pt.c (invalid_tparm_referent_p): Canonicalize the type of array offsets. Allow subobjects. gcc/c-family/ChangeLog: * c-cppbuiltin.c (c_cpp_builtins): Update __cpp_nontype_template_args for C++20. gcc/testsuite/ChangeLog: * g++.dg/cpp1z/nontype2.C: No error in C++20. * g++.dg/template/nontype25.C: No error in C++20. * g++.dg/template/nontype8.C: No error in C++20. * g++.dg/cpp2a/nontype-subob1.C: New test. * g++.dg/cpp2a/nontype-subob2.C: New test. * g++.dg/cpp1z/nontype3.C: Now C++17-only. * g++.dg/cpp2a/feat-cxx2a.C: Adjust expected value.
