--- Comment #17 from Carl Ponder <cpon...@nvidia.com> ---
I uploaded the two assembly-files. From the "sdiff", I think this is where the
allocations vary:
-Mnostack_arrays -Mstack_arrays
--------------------------------
-------------------------------
494 ..Dcfi3: ..Dcfi3:
495 subq $48, %rsp | subq $32, %rsp
496 movq %rbx, -24(%rbp) | movq %rbx,
-16(%rbp)
497 movq %r12, -32(%rbp) | movq %r12,
-24(%rbp)
498 movq %r13, -40(%rbp) | movq %r13,
-32(%rbp)
499 ## lineno: 38 ## lineno: 38
500 movq %rdi, %rbx movq %rdi, %rbx
501 movl (%rbx), %eax movl (%rbx), %eax
502 movl %eax, -16(%rbp) | movl %eax,
-8(%rbp)
503 movslq -16(%rbp), %rax | movslq -8(%rbp),
%rdi
504 movq %rax, -8(%rbp) | shlq $2, %rdi
505 leaq -8(%rbp), %rdi | call __builtin_aa
xorl %eax, %eax <
movl $.C2_299, %esi <
call pgf90_auto_alloc04 <
movq %rax, %r12 movq %rax, %r12
(I'm including the line-numbers, up to the point where they correspond between
the two files).
I'm guessing that these pgf90_auto_alloc04 / __builtin_aa are performing the
allocations, I'll check with PGI on this.
