Convert to avr-gcc

I have these in typedefn.h: #define flash __attribute__((__progmem__)) #define eeprom __attribute__((section(".eeprom")))

Then char foo[20] flash;

Thanks,

but i need a modifier to access to flash memory, to generate correct assembly code. I discovered that i have to use pgm_read_byte() macro (and friends) to allow the flash access: i guess that avr-gcc is not able to discover when the access is on a flash while CodevisionAvr yes .... otherwise the compiler generates memory access. Or i'm missing some options/modifiers ?

No, this is probably the biggest "problem" on avr-gcc compared to the other avr compilers. Especially if one has complex data structures that must live in flash. It would have been nicer if the compiler could automatically use the lpm instructions for any data in a specific section.
