[Bug c/18549] New: -save-temps option ends with corrupt object file

[Bug c/18549] New: -save-temps option ends with corrupt object file

[pschober at gmx dot ch]

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);
}

[Bug driver/18549] -save-temps option ends with corrupt object file

the following might be a similar problem:

if h8300-hms-gcc 3.3.1 is called with the -save-temps option on h8300-hms it 
produces
a wrong output architecture.
a call to the linker results in the following error message:
h8300-hms-ld: skipping incompatible main.o when searching for main.o
h8300-hms-ld: cannot find main.o

used call:
h8300-hms-gcc -mh -c -Wall -W -Wcast-qual -Wwrite-strings -Wno-unused -save-
temps main.cpp

i figured out that gcc creates h8300-architecture instead of h8300h, which is 
why
the linker fails. this can be checked with "h8300-hms-objdump.exe -f main.o".

omitting -save-temps resolves the problem.
OS: Win2000 (tested, behaviour can be reproduced)

Can you add -v and see what happens to be the difference between with and without -save-temps?

What I was trying to ask for was the output of:
avr-gcc -c -mmcu=atmega16 -save-temps foo.c -v 
avr-gcc -c -mmcu=atmega16 foo.c -v

It looks like you are mingw host.
If so, could you try trunk. This looks like dup of

This is correct. The avr toolset included in WinAVR is built as a MinGW 
host.
