thanks for having retested this, The tests are still not complete for
RTL generated functions, there are cases where no str/cmp wil be
emitted, because we can predict than the size is less than 4 and so have
a direct fallthru into the byte at a byte loop copying.
Also I will consider a size optimized implementation, so we don't jump
to the library
I will post examples for this shortly (and add them as a testcase) with
a strncmp implementation helper, that pertains to strcmp with constant
strings by the way. Please allow me some time to complete by benchmarking.
thanks for the hints about removing empty "" is the expanders
Kaz, before proceeding with the next patch, was your approval for 1/2
only or 2/2 with the expander cleanup ?
Many thanks,
Christian
