This patch removes for C++ the OpenMP 4.5 requirement that
a class may not be mapped if there are virtual members.
It does not do anything beyond and, as RTTI is not accessible
(→ OpenMP 5.2) and restrictions exists on using virtual
functions (5.0/5.2), that seems to be fine for now.

For sm_7x atomic stores we fall back on expand_atomic_store, but this

The following fixes a cut&paste error in disambiguating using restrict
info. Instead of using the for this purpose computed rbase1/rbase2
which preserve MEM_REF bases even when they are based on a decl the
code performs the check on the bases that drop info for those ...

Hi,
There's a nvidia driver JIT bug that mishandles this code (minimized from
builtin-arith-overflow-15.c):
...
int main (void) {
signed char r;
unsigned char y = (unsigned char) 0x80;
if (__builtin_sub_overflow ((unsigned char)0, (unsigned char)y, &r))
__builtin_abort ();
return 0;
}

One of the unusual target features of the Nvidia PTX ISA is that it
doesn't provide QI mode (byte sized) operations or registers.
[ FWIW: I recently happened to check this, and it actually supports

Hi Maciej:
OK for release branches, thanks!

This patch adds more support for _Float16 (HFmode) to the nvptx backend.
Currently negation, absolute value and floating point comparisons are
implemented by promoting to float (SFmode). This patch adds suitable
