Subject: [PATCH 6/9] create-diff-object: ignore changed of section
|
||
|
|
__patchable_function_entries
|
||
|
|
|
||
|
|
Linux 5.10 aarch64 uses -fpatchable-function-entry=N to generate N NOPs at the
|
||
|
|
beginning of each function, Section __patchable_function_entries is generated
|
||
|
|
to record the starting address of these NOPs.
|
||
|
|
|
||
|
|
Section __patchable_function_entries will change if the number of functions
|
||
|
|
changed during making hotpatch, here we just ignore the change of this section.
