[PATCH] SH2A: Don't push/pop registers for functions with resbank attribute

Thu, 29 Mar 2012 04:48:09 -0700 

Hi,

Please find attached the patch "resbank.patch" which fixes the issue
with "resbank" attribute. Currently, registers used in the routine are 
also saved on using resbank attribute. These registers are saved with
resbank instruction and need not be saved separately.
The patch fixes the issue. 

Tested with sh2a-elf. Regression results are good.
