> I just replaced expressions in calls to Py_MAX by variables: Py_MAX is a macro and it may have to compute each expression twice.
gcc computes those values only once. It even caches them for use in
PyUnicode_WRITE. But other compilers may not be so smart.
Instead of Py_MAX(a,b) here you can use a|b. In theory this should be
more efficient, but I couldn't see the difference even with microscope.
However, all this does not matter, soon I will submit complex patch,
which speeds up the utf-16 decoder in 2-5 times. |
