5.2.4 make.defaults |
| 14 |
"Variables to the right of the equals sign in the form ${foo} or $foo are recognised and expanded |
| 15 |
from variables previously set in this or earlier make.defaults files." |
| 16 |
5.3.1 Incremental Variables |
| 17 |
"Incremental variables must stack between parent and child profiles in the following manner: |
| 18 |
Beginning with the highest parent profile, tokenise the variable’s value based on whitespace and |
| 19 |
concatenate the lists. Then, for any token T beginning with a hyphen, remove it and any previous |
| 20 |
tokens whose value is equal to T with the hyphen removed, or, if T is equal to -*, remove all |
| 21 |
previous values. Note that because of this treatment, the order of tokens in the final result is |
| 22 |
arbitrary, not necessarily related to the order of tokens in any given profile. The following |
| 23 |
variables must be treated in this fashion: |
| 24 |
• USE |
| 25 |
• USE_EXPAND |
| 26 |
• USE_EXPAND_HIDDEN |
| 27 |
• CONFIG_PROTECT |
| 28 |
• CONFIG_PROTECT_MASK" |
