Added documentation of the defines for algorithms and assembly code and math. user_settings_embedded.h has configuration defines at the top that are set to 0 for off and 1 for on. Setting these turns on the appropriate defines.

# Set WC_CFG_* switches in a copy of a user_settings.h template, for CI configs
|
|
# that build the same template in more than one profile.
|
|
#
|
|
# Usage:
|
|
# set-user-setting.sh <user_settings.h> NAME=VALUE [NAME=VALUE ...]
|
|
#
|
|
# Why this exists rather than a sed in the JSON: a `sed -i` matching the whole
|
|
# line, interior alignment included, silently does nothing if the template is
|
|
# ever re-aligned, and the config then quietly tests the default profile
|
|
# instead of the one it names. This matches on the switch name alone and fails
|
|
# if a switch is missing, so a rename or a typo is a build failure rather than
|
|
# a test that stopped testing anything.
