[Bug c/18549] New: -save-temps option ends with corrupt object file
if gcc is called with the -save-temps option the resulting object file is
corrupt.
a call to the linker results in the following error message :
c:\programme\winavr\bin\..\lib\gcc-lib\avr\3.3.1\..\..\..\..\avr\lib\avr5\crtm16.o(.init9+0x0):undefined
reference to 'main'
without using the -save-temps option this error message doesn't appear.
if the file foo.s exists, the error doesn't appear as well (regardless of the
contents of foo.s);foo.s remains unchanged in this case
used calls :
avr-gcc -c -mmcu=atmega16 -save-temps foo.c
avr-gcc -mmcu=atmega16 -o foo.elf foo.o
this problem occurs on different versions (3.3.1, 3.4.1 tested) and on different
OS' (Windows 2000, Windows XP tested)
foo.c (works with other files as well) :
#include avr/io.h
int main(void)
{
while (1);
}
