Hi guys, I've been noticing some strange behaviour with my makefile arguments.
Firstly, LD.exe crashes when I use -mshort-calls with the --relax linker option, but *only* if I *don't* use -ffunction-sections and --gc-sections. With the latter two options enabled both -mshort-calls and --relax work just fine. Secondly, -ffunction-sections and --gc-sections seems to throw away some of my PROGMEM variables. I rely on a few PROGMEM variables being embedded into the binary so I can later distinguish which version it was compiled from, similar to: char PROGMEM buildtime[] = __TIME__; --gc-sections seems to remove this, although I thought it was only designed to remove unused functions and not PROGMEM data. Is there a workaround to this? Thanks for the help, - Dean _______________________________________________ AVR-libc-dev mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-libc-dev
