Changed paths:
M inline.h
M pod/perldelta.pod
M pp.c
M pp_hot.c
M t/op/64bitint.t
Log Message:
-----------
pp_{add,subtract,multiply}: use __builtin_{add,sub,mul}_overflow if available
This will hopefully make the code faster and smaller, and
make more cases to be handled as "simple common cases".
Note that this change uses HAS_BUILTIN_{ADD,SUB,MUL}_OVERFLOW macros
which have already been defined in config.h but seem not to have been
used by existing code.
t/op/64bitint.t: Add tests to exercise "simple common cases".
Note that these tests should pass even before this change.
Thanks to @tonycoz for advices to make this patch work better for
LLP64 platforms, especially Win32 x86-64.
