I wrote test.c as follows:
int main()
{
printf("Sizeof(int)=%d\n",sizeof(int));
return 0;
}
Then I use cilly to compile test.c,
FengZhu@FengZhu-PC /cygdrive/e
$cilly --mode=MSVC test.c
and get this output:
cl ./nologo /P /D_MSVC /DCIL=1 test.c
test.c
E:/cil/obj/x86_WIN32/cilly.asm.exe --out ./test.cil.c --MSVC ./test.i
Warning: Will work in MSVC mode but will be using machine-dependent
parameters for GCC since you do not have the MSVC compiler installed.
cl /nologo /P /D_MSVC ./test.cil.c
test.cil.c
cl /nologo /D_MSVC /c /Fo./test.obj /Tc ./test.cil.i
cl /nologo /D_MSVC /Fe./test.exe ./test.obj
Then I run test.exe
$./test.exe
and get an output:
Sizeof(int)=4
Thanks,
