What is wrong with it? Can't see why it does that...
>How-To-Repeat:
The compiler was configured as follows:
configure --prefix=$HOME/local --enable-languages=c --target=ia64-elf --with-ld=$HOME/bin/myld --with-as=$HOME/bin/myas --disable-c-mbchar --disable-threads --disable-shared --disable-nls
The compiler was called with the following options:
cc1 -da -O2 -fexpensive-optimizations -fstrict-aliasing -o addv.s addv.c
