[openssl-dev] [openssl.org #4568] Enhancement request: Capability vector accessor function for arm and ppc

[Loic Etienne via RT]

For arm and ppc, define functions corresponding to unsigned long *OPENSSL_ia32cap(), returning a pointer to the capability vector, or NULL on an unsuitable architecture:
unsigned int *OPENSSL_armcap_loc();
unsigned int *OPENSSL_ppccap_loc();

Otherwise, an extern declaration of OPENSSL_armcap_P (or OPENSSL_ppccap_P) is required, depending on the architecture, which has to be detected by other means. This is inconvenient. Furthermore, arm_arch.h and ppc_arch.h not available in the deployed include folder, making a declaration mismatch possible.

Further architectures may be considered as well.
