On Ubuntu 18.04LTS with SDCC 3.5.0 doing "make clean" and then "make" gives a binary 12,212 bytes in size, which is a bit tight (but still 1K free). I think newer versions of SDCC might be less efficient at code generation. If you do want to build it, SDCC has few dependencies, so I think it is possible to install older versions of the package. Other compilers (e.g. Keil) are probably even more efficient, but I don't have a license for the 8051, and also it's not free.

I found sdcc 3.5.0 and now make works but I get the following:

PHP Code:

Name                 Start    End      Size     Max     
   ---------------- -------- -------- -------- --------
   ROM/EPROM/FLASH  0x0000   0x2fb7   12216    13312 


I guess you won't have room for any trigonometric functions like sine, cosine, etc., eh?
