| Gilles Peskine | edc2379 | 2023-09-04 17:53:11 +0200 | [diff] [blame] | 7 | * Automatically enable certain dependencies. Generally, MBEDLTS_xxx |
| 8 | * configurations need to be explicitly enabled by the user: enabling |
| 9 | * MBEDTLS_xxx_A but not MBEDTLS_xxx_B when A requires B results in a |
| 10 | * compilation error. However, we do automatically enable certain options |
| 11 | * in some circumstances. One case is if MBEDTLS_xxx_B is an internal option |
| 12 | * used to identify parts of a module that are used by other module, and we |
| 13 | * don't want to make the symbol MBEDTLS_xxx_B part of the public API. |
| 14 | * Another case is if A didn't depend on B in earlier versions, and we |
| 15 | * want to use B in A but we need to preserve backward compatibility with |
| 16 | * configurations that explicitly activate MBEDTLS_xxx_A but not |
| 17 | * MBEDTLS_xxx_B. |
