Sorry, yes, you are right. There is a small performance penalty when
every function marked as inline is, in fact, inlined. There are other

06:40 PM Ruby Feature #10081 (Closed): [PATCH] Specifying MACRO for increase performence in ppc64

To increase performance on ppc64 machines, the MACRO "powerpc64" were specified for the architecture, just like for x86_64 machines.
I've executed some benchmarks, see below:

04:50 PM Ruby Bug #10080 (Rejected): Functions marked as "static inline" are not inlined by gcc

Since GCC 4.8.3, some static inline functions (such as rb_call0) are not
inlined in the generated machine code. This happens in both x86-64 and ppc64
platforms and it can be verified by using the following commands:
