lib/test_hash.c: fix warning in preprocessor symbol evaluation

2016-10-07T13:21:26+00:00

commit e6173ba42bbdba05fd4f3021c0beda0506271507 upstream. Some versions of gcc don't like tests for the value of an undefined preprocessor symbol, even in the #else branch of an #ifndef: lib/test_hash.c:224:7: warning: "HAVE_ARCH__HASH_32" is not defined [-Wundef] #elif HAVE_ARCH__HASH_32 != 1 ^ lib/test_hash.c:229:7: warning: "HAVE_ARCH_HASH_32" is not defined [-Wundef] #elif HAVE_ARCH_HASH_32 != 1 ^ lib/test_hash.c:234:7: warning: "HAVE_ARCH_HASH_64" is not defined [-Wundef] #elif HAVE_ARCH_HASH_64 != 1 ^ Seen with gcc 4.9, not seen with 4.1.2. Change the logic to only check the value inside an #ifdef to fix this.

: Add support for architecture-specific functions

2016-05-28T19:48:31+00:00

This is just the infrastructure; there are no users yet. This is modelled on CONFIG_ARCH_RANDOM; a CONFIG_ symbol declares the existence of . That file may define its own versions of various functions, and define HAVE_* symbols (no CONFIG_ prefix!) to suppress the generic ones. Included is a self-test (in lib/test_hash.c) that verifies the basics. It is NOT in general required that the arch-specific functions compute the same thing as the generic, but if a HAVE_* symbol is defined with the value 1, then equality is tested.
