[avr-gcc-list] main function registers push/pop
My main function never return, I want to eliminate registers push/pop in main function. I read the list archives, found: OS_main - gcc 4.3.3 not implement OS_task - gcc 4.3.3 OK but interrupt not guarantee disable -mtiny-stack - not for what I wanted. In old day, gcc 4.0.3 can identify main function, registers push/pop were not generated. Dmitry: It would be the best variant to restore old behavior and add '-m...' option for generation of standart prologue/epilogue with main(). I prefer -m... option, implemented? -- -- Kang Tin Lai ___ AVR-GCC-list mailing list AVR-GCC-list@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
