Purpose
|
||
|
|
|
||
|
|
This script is a small wrapper around the abi-compliance-checker and
|
||
|
|
abi-dumper tools, applying them to compare the ABI and API of the library
|
||
|
|
files from two different Git revisions within an Mbed TLS repository.
|
||
|
|
The results of the comparison are formatted as HTML and stored at
|
||
|
|
a configurable location. Returns 0 on success, 1 on ABI/API non-compliance,
|
||
|
|
and 2 if there is an error while running the script.
|
||
|
|
Note: must be run from Mbed TLS root.
