Bug #: 51909 Summary: for avr device : internal error in linking phase , function call disappearing when assembled and a weird compiling warning Classification: Unclassified Product: gcc Version: 4.5.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: gnumauroru...@gmail.com Created attachment 26387 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26387 make commands list Dears, unfortunely I am new in gcc compiler. I wok on Windows XP Home - SP3. I had a problem in AVR Toolchain, which uses gcc 4.5.1 It seems maybe they have an adapted gcc version "gcc (AVR_8_bit_GNUToolchain_3.3.1_422) 4.5.1" I also downloaded and installed cgwin. It contains gcc 4.5.3 Because of I am novice in gcc, at the moment I did not try to reproduce the problems with the gcc 4.5.3 inside cgwin. I have three problems : - internal error in the linking phase (warning) - function declared 'noreturn" has a 'return' statement given on a function where no return statement appears - a function call which disappears when the firmware is built The same function call does not disappear if it is written in an equivalent but different style. At the moment I posted all details on AVR Freaks : http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&p=914857#914857 Please, let me know if you can help me to try to reproduce the problem in gcc 4.5.3 in cgwin I attach the Output of AVR Studio, which shows the make commands performed. Best Regards, Mauro.
