Hi all, is there any possibilty to really hard bind a variable to a general purpose reg? When i try binding it with register uint8_t test asm("r3") it can still be moved to the sram. It is critical for my work, to have it strictly bound to a reg. Is there any way to achieve that? i ve tried it with avr-gcc 4.3.3 as well as with a 4.4.1 version with the IRA features. Where could i find the declaration of the normal "register" attribute in the gcc_binutil-sources? Could it be a solution to define a new attribute including hard constraints for specific regs? Is there any documentation to that topic?
