But on powerpc64 ( system clang from head -r339076 ):
# clang -dM -E -x c /dev/null | grep -i __power
#define __POWERPC__ 1
#define __powerpc64__ 1
#define __powerpc__ 1
and (I only have the one gcc* vintage around):
# gcc8 -dM -E -x c /dev/null | grep -i __power
#define __powerpc64__ 1
#define __powerpc__ 1
so the following are used on powerpc64:
+#ifdef UNR64_LOCKED
+uint64_t alloc_unr64(struct unrhdr64 *);
+#else
. . .
and:
+#ifdef UNR64_LOCKED
+uint64_t
+alloc_unr64(struct unrhdr64 *unr64)
+{
+ uint64_t item;
+
+ mtx_lock(&unitmtx);
+ item = unr64->counter++;
+ mtx_unlock(&unitmtx);
+ return (item);
+}
+#endif
Was that the intent for powerpc64?
Notes about the powerpc64 context used:
