c++: member vs global template [PR106310]
|
||||
|
||||
For backward compatibility we still want to allow patterns like
|
||||
this->A<T>::foo, but the template keyword in a qualified name is
|
||||
specifically to specify that a dependent name is a template, so don't look
|
||||
in the enclosing scope at all.
|
||||
|
||||
Also fix handling of dependent bases: if member lookup in the current
|
||||
instantiation fails and we have dependent bases, the lookup is dependent.
|
||||
We were already handling that for the case where lookup in the enclosing
|
||||
scope also fails, but we also want it to affect that lookup itself.

fortran: Fix ICE on pr96024.f90 on big-endian hosts [PR96024]
|
||||
|
||||
The pr96024.f90 testcase ICEs on big-endian hosts. The problem is
|
||||
that length->val.integer is accessed after checking
|
||||
length->expr_type == EXPR_CONSTANT, but it is a CHARACTER constant
|
||||
which uses length->val.character union member instead and on big-endian
|
||||
we end up reading constant 0x100000000 rather than some small number
|
||||
on little-endian and if target doesn't have enough memory for 4 times
|
||||
that (i.e. 16GB allocation), it ICEs.
