# Compares bytecode reports from multiple compiler versions and platforms to
|
||
|
|
# determine if there are any differences.
|
||
|
|
#
|
||
|
|
# The script does not accept any arguments.
|
||
|
|
#
|
||
|
|
# The reports should be placed in subdirectories of the current working
|
||
|
|
# directory and their names should follow one of the following patterns:
|
||
|
|
#
|
||
|
|
# report-solc-<platform>-v<solidity version>+commit.<commit hash>.txt
|
||
|
|
# report-soljson-<platform>-v<solidity version>+commit.<commit hash>.js.txt
|
||
|
|
#
|
||
|
|
# Reports corresponding to the same version and commit hash are grouped together
|
||
|
|
# and the script succeeds only if the files within each group are identical.
