Several VEC member functions that accept an element 'T' used to have
two overloads: one taking 'T', the second taking 'T *'.
This used to be needed because of the interface dichotomy between
vectors of objects and vectors of pointers. In the past, vectors of
pointers would use pass-by-value semantics, but vectors of objects
would use pass-by-reference semantics. This is no longer necessary,
but the distinction had remained.
The main side-effect of this change is some code reduction in code
that manipulates vectors of objects. For instance,
- struct iterator_use *iuse;
-
- iuse = VEC_safe_push (iterator_use, heap, iterator_uses, NULL);
- iuse->iterator = iterator;
- iuse->ptr = ptr;
+ struct iterator_use iuse = {iterator, ptr};
+ VEC_safe_push (iterator_use, heap, iterator_uses, iuse);
Compile time performance was not affected.
Tested on x86_64 and ppc64.
Also built all-gcc on all targets using VEC routines: arm, bfin, c6x,
epiphany, ia64, mips, sh, spu, and vms.
