GCC4.0.0 - Query

Subject: GCC4.0.0 - Query

Hi, I am currently working on GCC Instruction Scheduling pass. The previous versions of GCC, from GCC-3.3 onwards, had the provision to insert NOP-rtl appropriately during Instruction Scheduling pass(haifa.c : schedule_block). This is required for machine-architectures which do not support hardware-stall and requires compiler to insert NOP. However, GCC4.0.0 does not contain this code to insert NOP rtl.

Is there any technical reason behind this? Can anyone please clarify about this matter?
