--- Comment #14 from Mikael Morin <mikael at gcc dot gnu.org> ---
The tree optimized dumps are almost the same for 32 and 64 bits.
The expand dumps show more significant differences.
The 64 bits dump shows the register r4 is saved to memory with:
(insn 3 2 4 2 (set (mem/c:QI (plus:DI (reg/f:DI 111 virtual-incoming-args)
(const_int 8 [0x8])) [10 c+0 S1 A64])
(reg:QI 4 4 [ c ])) "pr110419_comment4.f90":6:16 -1
(nil))
The 32 bits dump shows:
(insn 3 2 4 2 (set (reg/v:SI 119)
(reg:SI 4 4)) "pr110419_comment4.f90":6:16 -1
(nil))
(insn 4 3 5 2 (set (reg:QI 120)
(mem/c:QI (reg/v:SI 119) [10 c+0 S1 A8])) "pr110419_comment4.f90":6:16
-1
(nil))
