[Bug c++/58074] [C++11][DR 1333] __is_trivial intrinsic fails for deleted members and for non-trivial copy-c'tors
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58074 --- Comment #10 from Daniel Krügler --- (In reply to Jonathan Wakely from comment #9) > (In reply to Daniel Krügler from comment #0) > > The deleted default constructor should not prevent type Trivial of being > > trivial (Maybe this part of the problem is related to bug 52707, but I'm not > > sure). > > I think DR 1363 changed that (and DR 1496 reconfirmed it) so the first test > is wrong. But G++ now passes that assertion, so that's also wrong (that is > Bug 85723 though). I agree in regard to DR 1496. The history behind that was that during the Portland 2012 CWG drafting of that issue the following wording suggestion was provided: "A trivial class is a class that is trivially copyable and has either a trivial default constructor or no default constructor (12.1 class.ctor)." That wording had the effect that classes with either deleted or no default constructor could be trivial and made these two cases consistent as pointed out by DR 1496. That P/R was then later rejected and modified to the now accepted wording at the Kona 2015 meeting, which also had the effect of making the two cases consistent in a now a different way, by imposing the requirement that at least one non-deleted default constructor exists. I don't think that DR 1363 changed the situation, because the meaning of the 1363 wording still didn't exclude deleted constructors from being trivial.
[Bug fortran/71861] [7/8/9 Regression] [F03] ICE in write_symbol(): bad module symbol

How should the compiler > behave? Does Note 15.2 in F2018 apply? An interface body cannot be used to describe the interface of an internal procedure, a module procedure that is not a separate module procedure, or an intrinsic procedure because the interfaces of such procedures are already explicit. However, the name of a procedure can appear in a PROCEDURE statement in an interface block (15.4.3.2).

[Bug target/89746] powerpc-none-eabi-gcc emits code using stfiwx to misaligned address
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89746 --- Comment #2 from Segher Boessenkool --- (This is on a PowerPC 750). The compiler makes an unaligned store for this, because it knows no better than it is just a SImode store: d_5 = (int) f_4(D); _10 = (unsigned int) d_5; MEM[(short int *)p_7(D) + 6B] = _10; and *normal* unaligned stores of SImode are just fine -- they just cause an extra access if crossing an 8B boundary. OTOH, floating point load/store cause a misalignment interrupt if unaligned.
