[C++ Patch] PR 83921 ("[7/8 Regression] GCC rejects constexpr initialization of empty aggregate")

Hi, I'm finishing testing on x86_64-linux the below - which anyway seems very unlikely to cause regressions because we aren't really stress testing the relevant checks in potential_constant_expression_1 much, if at all (surely stmtexpr19.C tests static). Anyway, the issue is the following. I

[C++ PATCH] Fix ICE in potential_constant_expression_1 (PR c++/83918)

Hi! Before location wrappers were introduced, the potential_constant_expression_1 assumption that a VIEW_CONVERT_EXPR must have non-NULL type was right, if it is a type dependent reinterpret cast, it would be REINTERPRET_CAST_EXPR instead. Location wrappers around decls can have NULL type, if the

[C++ PATCH] Avoid spurious -Wignored-qualifiers warning on artificial C++17 P0138R2 cast (PR c++/83919)

Hi! These casts for P0138R2 isn't something the user typed in their code, so diagnosing -Wignored-qualifiers on these looks wrong. -Wuseless-cast has been handled similarly in the past already. Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk? 2018-01-18 Jakub Jelinek

[PATCH] Fix unwind info in x86 interrupt functions (PR debug/83728)

Hi! Last summer i386 INCOMING_FRAME_SP_OFFSET macro has been changed, so that it is one word for most of the functions (as previously always), but 2 words for functions with interrupt attribute. Unfortunately this breaks the unwind info, as can be seen on the gcc.dg/guality/pr68037-1.c testcase.

[PATCH] -Warray-bounds: Fix false positive in some "switch" stmts (PR tree-optimization/83510)

PR tree-optimization/83510 reports that r255649 (for PR tree-optimization/83312) introduced a false positive for -Warray-bounds for array accesses within certain switch statements: those for which value-ranges allow more than one case to be reachable, but for which one or more of the VR-unreachable

[C++ PATCH] Fix ICE in joust with -Wconversion (PR c++/81167)

Hi! As mentioned in the PR, we ICE on this testcase because w->fn is a conversion operator, w->convs[0]->type is a reference to a class type, but because that conversion is ck_ref_bind, source_type looks through it and finds ck_identity with the class type. Then we because w->fn is not a construc

libgo patch committed: Use rlimit64 when we use getrlimit64

This libgo patch changes the syscall package to use the rlimit64 type, if available, when we use getrlimit64. This makes no difference on most systems, because renames the type appropriately anyhow, but apparently it makes a difference on AIX. Bootstrapped and ran Go testsuite on x86_64-pc-linux
