A diff of "gcm128c" between -current and netbsd-9 before the pullup
-# if defined(__arch64__)
-# define GHASH_ASM_SPARC
-# define GCM_FUNCREF_4BIT
+# define GHASH_ASM_SPARC
+# define GCM_FUNCREF_4BIT
extern unsigned int OPENSSL_sparcv9cap_P;
void gcm_init_vis3(u128 Htable, const u64 Xi);
void gcm_gmult_vis3(u64 Xi, const u128 Htable);
void gcm_ghash_vis3(u64 Xi, const u128 Htable, const u8 *inp,
That is, before the pull-up of OpenSSL 1.1.1k, the "GHASH_ASM_SPARC"
macro was conditionally defined iff "__arch64__" was also defined--
likely an internal compiler definition.
With -current and netbsd-9 after the pull up, that conditionalization
has been removed. The supplied assembly code (wrapped in a perl
script) implies by filename that it is for sparcv9 and up CPUs.
Alas I don't know sparc assembly, so I will have to defer to others
whether it can be rendered harmless for sparcv8 and prior CPUs.
Or just reinstate the above conditionalization.
