To emphasize this point: on 64-bit x86 with frame pointers, you have twice as many registers as on 32-bit x86 without frame pointers, and these registers are twice as wide. A 64-bit value (more common than you'd expect even when pointers are 32 bits) takes two registers on 32-bit x86, but only a single register on 64-bit x86.

To emphasize this point: on 64-bit x86 with frame pointers, you have twice as many registers as on 32-bit x86 without frame pointers, and these registers are twice as wide. A 64-bit value (more common than you'd expect even when pointers are 32 bits) takes two registers on 32-bit x86, but only a single register on 64-bit x86.
So there's no point in disabling frame pointers for 32-bit code running on a 64-bit processor then?
