@ -9,10 +9,10 @@ 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.
The results of the comparison are either formatted as HTML and stored at
a configurable location, or a brief list of problems found is output.
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.
