2020-12-24C++ : Add the -stdlib= option.Iain Sandoe10-13/+216
This option allows the user to specifiy alternate C++ runtime libraries, for example when a platform uses libc++ as the installed C++ runtime. We introduce the command line option: -stdlib= which is the user-facing mechanism to select the C++ runtime to be used when compiling and linking code. This is the same option spelling as that used by clang to allow the use of libstdc++. The availability (and thus function) of the option are a configure-time choice using the configuration control: --with-gxx-libcxx-include-dir= Specification of the path for the libc++ headers, enables the -stdlib= option (using the path as given), default values are set when the path is unconfigured. If --with-gxx-libcxx-include-dir is given together with --with-sysroot=, then we test to see if the include path starts with the sysroot and, if so, record the sysroot-relative component as the local path. At runtime, we prepend the sysroot that is actually active. At link time, we use the C++ runtime in force and (if that is libc++) also append the libc++abi ABI library. As for other cases, if a target sets the name pointer for the ABI library to NULL the G++ driver will omit it from the link line. gcc/ChangeLog: * configure.ac: Add gxx-libcxx-include-dir handled in the same way as the regular cxx header directory. * Makefile.in: Regenerated. * config.in: Likewise. * configure: Likewise. * cppdefault.c: Pick up libc++ headers if the option is enabled. * cppdefault.h (struct default_include): Amend comments to reflect the extended use of the cplusplus field. * incpath.c (add_standard_paths): Allow for multiple c++ header include path variants. * doc/invoke.texi: Document the -stdlib= option. gcc/c-family/ChangeLog: * c.opt: Add -stdlib= option and enumerations for libstdc++ and libc++. gcc/cp/ChangeLog: * g++spec.c (LIBCXX, LIBCXX_PROFILE, LIBCXX_STATIC): New.

2020-12-23c++: EOF location [PR 96045]Nathan Sidwell48-60/+59
Setting the EOF token location to be the start of a line just after the ending newline is not most helpful. While that location is probably the right place to report preprocessing and lexing issues, when parsing, the location just after the last token is better. That way we get to point at some actual text. Setting the location from the previous token has the advantage over just setting the location to be the end of the final line, in that any ending comments do not get considered, which I think is better.

unsafe_return_slot_p wasn't recognizing an empty base as potentially-overlapping, which it definitely is.

2020-12-23compiler: nil-checked pointers and index expressions can trapIan Lance Taylor2-7/+5
The compiler was treating indirections through pointers that had been explicitly checked against nil and slice and string index expressions as non-trapping memory references. That is true for ordinary Go programs, but it isn't true if the programs construct their own memory addresses. In particular it isn't true for the kinds of programs that want to use runtime.SetPanicOnFault. The effect of this will be slightly larger binaries, due to additional exception information, and perhaps slightly less optimization.

2020-12-23c++: Fix up floating point complex handling in build_zero_init_1 [PR98353]Jakub Jelinek1-1/+1
While the gimplifier patch I've just committed fixed an ICE, in some cases like on the committed testcase cp folding doesn't happen after build_zero_init_1 because it is called already during gimplification. For the scalar types, if we want to use convert, the problem with complex floats is that it returns a COMPLEX_EXPR with FLOAT_EXPR arguments which have INTEGER_CST 0 as argument. As fold isn't recursive, it doesn't do anything in that case, we need to first fold those FLOAT_EXPRs to REAL_CST 0.0 and only afterwards the COMPLEX_EXPR can be folded into COMPLEX_CST with 0.0 arguments. This patch instead just uses build_zero_cst that creates the zero constant for any scalar types (and more) directly, instead of going through multiple hops. 2020-12-23 Jakub Jelinek <jakub@redhat.com> PR c++/98353 * init.c (build_zero_init_1): Use build_zero_cst for SCALAR_TYPE_P zero initializers.

2020-12-23i386: Fix __builtin_trunc with FE_DOWNWARD rounding direction [PR96793]Uros Bizjak2-13/+42
x86_expand_truncdf_32 expander uses x86_sse_copysign_to_positive, which is unable to change the sign from - to +. When FE_DOWNWARD rounding direction is in effect, the expanded sequence that involves subtraction can trigger x - x = -0.0 special rule. x86_sse_copysign_to_positive fails to change the sign of the intermediate value, assumed to always be positive, back to positive.

This is the gofrontend version of https://golang.org/cl/245125. Original CL description: Currently, we include a "kind" field on scase to distinguish the three kinds of cases in a select statement: sends, receives, and defaults. This commit removes by kind field by instead arranging for the compiler to always place sends before receives, and to provide their counts separately. It also passes an explicit "block bool" parameter to avoid needing to include a default case in the array. It's safe to shuffle cases like this because the runtime will randomize the order they're polled in anyway. For golang/go#40410.

2020-12-22runtime: add "success" field to sudogIan Lance Taylor4-23/+29
This is the gofrontend version of https://golang.org/cl/245019. Original CL description: The current wakeup protocol for channel communications is that the second goroutine sets gp.param to the sudog when a value is successfully communicated over the channel, and to nil when the wakeup is due to closing the channel. Setting nil to indicate channel closure works okay for chansend and chanrecv, because they're only communicating with one channel, so they know it must be the channel that was closed. However, it means selectgo has to re-poll all of the channels to figure out which one was closed. This commit adds a "success" field to sudog, and changes the wakeup protocol to always set gp.param to sg, and to use sg.success to indicate successful communication vs channel closure. While here, this also reorganizes the chansend code slightly so that the sudog is still released to the pool if the send blocks and then is awoken because the channel closed. For golang/go#40410 This is being brought over to gofrontend as a step toward upgrading to Go1.16beta1, setting up for more compiler changes related to select handling.

2020-12-22runtime: omit nil-channel cases from selectgo's ordersIan Lance Taylor2-41/+29
This is the gofrontend version of https://golang.org/cl/245123. Original CL description: Currently, selectgo does an initial pass over the cases array to look for entries with nil channels, so they can be easily recognized and skipped later on. But this still involves actually visiting the cases. This commit changes selectgo to omit cases with nil channels when constructing pollorder, so that they'll be skipped over entirely later on. It also checks for caseDefault up front, which will facilitate changing it to use a "block bool" parameter instead.

2020-12-22c++: Handle array members in build_comparison_op [PR93480]Jakub Jelinek3-5/+162
http://eel.is/c++draft/class.compare.default#6 says for the expanded list of subobjects: "In that list, any subobject of array type is recursively expanded to the sequence of its elements, in the order of increasing subscript." but build_comparison_op just tried to compare the whole arrays, which failed and therefore the defaulted comparison was deleted. The following patch instead compares the array elements, and if info.defining, adds runtime loops around it so that it iterates over increasing subscripts. For flexible array members it punts, we don't know how large those will be, for zero sized arrays it doesn't even try to compare the elements, because if there are no elements, there is nothing to compare, and for [1] arrays it will not emit a loop because it is enough to use [0] array ref to cover everything. 2020-12-21 Jakub Jelinek <jakub@redhat.com> PR c++/93480 * method.c (common_comparison_type): If comps[i] is a TREE_LIST, use its TREE_VALUE instead.

2020-12-21c++: Add some asserts in mangle.cJason Merrill1-2/+8
The added asserts are places I noticed that we aren't adding the "on" to distinguish an operator name from an expression involving the operator. Hopefully that's because operator names never get there; if not, crash bug reports will let us fix the issue. gcc/cp/ChangeLog: * mangle.c (write_member_name): Add assert. (write_expression): Add asserts.
2020-12-21c++: Fix demangling of <unresolved-name>Jason Merrill3-22/+72
The ABI for unresolved scoped names on the RHS of . and -> used to be sr <type> <unqualified-id> That changed years ago to something more complex, but G++ was never updated. This change was particularly incompatible for simple qualified-ids like A::x, which were previously mangled as sr1A1x, and now sr1AE1x. This obviously makes life hard for demanglers, which can't know whether to consume that E or not. To work around this, we now try demangling with the newer ABI, and if that fails and we saw an "sr", try again with the older ABI. libiberty/ChangeLog: PR c++/67343 * cp-demangle.h (struct d_info): Add unresolved_name_state. * cp-demangle.c (d_prefix): Add subst parm. (d_nested_name): Pass it. (d_unresolved_name): Split out from... (d_expression_1): ...here. (d_demangle_callback): Maybe retry with old sr mangling. * testsuite/demangle-expected: Add test.
