Is there a limit on any of the sections (.text,.bss,.data) when using PIC on ARM architectures? As far as I have read there used to be a size limitation for .data+.bss on m68k architectures of 32K and for .text there is a limit of 64K. This only applies to the PIC executable format. 
Are there any similar restrictions for XIP on ARM?

Thanks.
