Subject: [PATCH] backends: Fix arm_machine_flag_name version string.
|
||
|
|
|
||
|
|
arm_machine_flag_name checks the version byte and if not zero returns
|
||
|
|
a version string. There are only 5 versions defined. So check the
|
||
|
|
version byte is not larger.
|
||
|
|
|
||
|
|
* backends/arm_machineflagname.c (arm_machine_flag_name):
|
||
|
|
Check version <= 0, otherwise return NULL.
