Fix PR 10153: tail recusion for vector types.
The problem here is we try to an initialized value
from a scalar constant. For vectors we need to do
a vect_dup instead. This fixes that issue by using
build_{one,zero}_cst instead of integer_{one,zero}_node
when calling create_tailcall_accumulator.
Changes from v1:
* v2: Use build_{one,zero}_cst and get the correct type before.
OK? Bootstrapped and tested on aarch64-linux-gnu with no regressions.
gcc/ChangeLog:
PR tree-optimization/10153
* tree-tailcall.c (create_tailcall_accumulator):
Don't call fold_convert as the type should be correct already.
(tree_optimize_tail_calls_1): Use build_{one,zero}_cst instead
of integer_{one,zero}_node for the call of
create_tailcall_accumulator.
gcc/testsuite/ChangeLog:
PR tree-optimization/10153
* gcc.c-torture/compile/pr10153-1.c: New test.
* gcc.c-torture/compile/pr10153-2.c: New test.

After some further discussion on the DragonFly lists and further reading on my
part, I found out that %sil and %dil are the 8-bit equivalents of %al, %bl, etc.
(Watch the light bulb undim in my head here :-)
It would be better if gcc were able to diagnose the problem code better (ensure
that the architecture is valid before emitting a %sil/%dil/%bpl/%spl register)
-- I'll see if I can't ponder on this and propose a small patch.

Richard -- agreed with your comment, but I think the larger issue is that GCC is
choosing phantom registers (%sil/%dil). Yonetani Tomokazu on the DragonFly BSD
lists has seen this issue compiling straight C code with "-march=pentium4 -O".
Any ideas where to look? I'll try to get a sample of failing source (along with
GCC versions and the other goodies) and see where it's dying.

I'm of the opinion that the source is invalid. Using a "=q" constraint
instead of an "=r" constraint properly shows that the compiler must choose
one of the four "low byte" registers.
You might object that the compiler should "know" that it cannot place a
character object into %esi/%edi/%ebp, but that's not true at all -- we
cannot store a character to memory from those registers, but we can hold
a character value in those registers.
