X-Bugzilla-Reason: CC X-SW-Source: 2005-02/txt/msg02660.txt.bz2 List-Id: Although I don't believe this is a regression, I do believe it's a bug which should ideally be remedied as soon as reasonably possible; as it seems unreasonable to require any target to support data types more than twice as large as it's pointer type, or required by the language standards; so feel that this should be considered a reasonably important failure to remedy. To demonstrate this bug, simply reduce the defined long long size in avr.h to the size of a long which is defined as being 32-bits; resulting in: In file included from /Applications/avr/avr-src/gcc/unwind-dw2.c:36: /Applications/avr/avr-src/gcc/unwind.h:59: error: unable to emulate 'DI' In file included from /Applications/avr/avr-src/gcc/unwind-dw2.c:40: /Applications/avr/avr-src/gcc/unwind-pe.h: In function 'read_encoded_value_with_base': /Applications/avr/avr-src/gcc/unwind-pe.h:191: error: unable to emulate 'DI' /Applications/avr/avr-src/gcc/unwind-pe.h:194: error: unable to emulate 'DI' make[2]: *** [libgcc/./unwind-dw2.o] Error 1 -- Summary: 4.0 bootstrap unreasonably requires 64-bit target type mode support.
