+Subject: [PATCH] xtest: add -DOPENSSL_API_COMPAT=10100
+
+regression_1000.c uses OpenSSL functions that have been deprecated
+after version 1.1. In particular, building with version 3.0 causes the
+following error (and other similar ones not pasted here):
+
+ optee_test/host/xtest/regression_1000.c: In function 'check_signature':
+ optee_test/host/xtest/regression_1000.c:2735:9: error: 'SHA256_Init' is deprecated: Since OpenSSL 3.0 [-Werror=deprecated-declarations]
+  2735 |         SHA256_Init(&ctx);
+       |         ^~~~~~~~~~~
+
+Add -DOPENSSL_API_COMPAT=10100 to the build flags to avoid this and be
+flexible with regards to which version of OpenSSL build environment has
+to provide.
