[cfe-dev] clang assembler problems

[kalyan ponnala]

hi,
I tried this by installing MinGW. When I execute a small program like
helloworld.c

#include<stdio.h>
int main()
{
printf("\n hello world");
return 0;
}


It gives the output as given in this snapshot. It still connects to mingw
but the assembler cant figure out these statements i guess. It is giving
errors as shown in the snapshot. Do you know why is it doing this?

Thanks
