Re: [PATCH 5/9] exec/address-spaces: Wrap address space singletons into functions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On 20/9/22 01:17, Bernhard Beschow wrote:
In the next steps, these singletons will be resolved by turning them
into attributes of the system bus. The system bus is already accessible
via the global current_machine variable which will be made use of later
in the wrapper functions.

All changes have been performed with search-and-replace:
* s/&address_space_memory/get_address_space_memory()/
* s/&address_space_io/get_address_space_io()/
The only exceptions were exec/address-spaces.h and softmmu/physmem.c
which have been manually changed.
