I do not have access to the IAR compiler. Soonly included the free
z88dk compiler, and some non-free compilers that have time-limited
evaluation versions.
I already saw it in the discussion you mentioned earlier, and was about
to write to you about them. The IAR results are impressive in terms of
code size. When I made the benchmark
http://colecovision.eu/stuff/testbench.tar.gz years ago, I did choose
files, where HITECH-C performed much better than sdcc. And then worked
on improving sdcc until it was better than HITECH-C for them. So the IAR
results set a kind of new goal to reach for sdcc.
For including the results on the comparison page I would like to also
have a version compiled with comparable options to sdcc: No use of
undocumented instructions, and all functions compiled as reentrant.
