First a note: I removed -ffunction-sections from the compiler options, and it is now better, but not good enough (365KB). It was an options the AVR IDE defaulted to, that is why I not noticed it. OMIT_DISKIO is also NOT defined. I am using SQLite version 3.6.4. OTHER_OS=1 and THREADSAFE=0.
At first try, I just used the amalgamation from the site and put the SQLITE_OMIT_* lines at the beginining of the source file. It was only after then I noticed in the online docs that to correctly use the OMIT defines, I have to start from full sources. So I got the tarball, used Makefile.gcc-linux as a template to make my own makefile (I defined the OMIT options), and issued a "make -f Makefile.gcc-avr sqlite3.c". (Although I have no idea how the Tcl script would use defines from the makefile, I assume some of the tools (lemon?) involved try to parse the make- and source files like a very basic preprocessor, so it is possible.) Again, OMITs are prepended to sqlite3.c. I use the (atmel supplied) AVR32 gcc compiler to compile with "-Os -fno-inline -Wall -c -fmessage-length=0 -mpart=uc3b1256es". These are all the gcc options in use, and now I get 365KB. As an experiment, I also tried to compile with the x86 gcc 4.3.2 to see the size it produces, with the same options I got 315KB. Definitely better but still far too large. So, on one hand the AVR32 compiler is not that good for producing small code, but I am also missing something important, because the x86 object file is also much larger than the size you mentioned (315KB vs 205KB). Not to mention that 315KB is without optional features, the 205KB you mentioned is with them. These are the exact actions I took. Any help is appretiated.
