SWP Kernel Test
|
||
|
||
usage: ./swp_test
|
||
|
||
Description:
|
||
The use of SWP is deprecated in ARMv6 and above. Since there are a number of existing Android
|
||
apps that use this instruction, we need to make sure that the SWP emulation feature is present
|
||
and enabled in our kernels. This kernel test is to emulate the deprecated ‘swp’ instruction
|
||
|
||
|
||
SWP Rt, Rt2, [Rn]
|
||
|
||
Rt : is the destination register.
|
||
Rt2 : is the source register. Rt2 can be the same register as Rt.
|
||
Rn : contains the address in memory. Rn must be a different register from both Rt and Rt2.
