Hi,cil-mail-list:
=09What I send before can not display correctly, resend again.=
Sorry
=09I try to compiler Linux-2.6.12 kernel using cil. The following=
is the difference between stand kernel and our kernel.
Note that: I change include/linux/compiler-gcc3.h because cil can=
not process the __attribute__ option of gcc.

When I compiler kernel, the following error ocurred:
-----------------------------------------------------------------=

-----------------------------------------------------------------=
-----------------------------------------------------
It is obvious that cil can not process the following code=
correctly:
---------------------------------------
static __initdata enum state {
Start,
Collect,
GotHeader,
SkipIt,
GotName,
CopyFile,
GotSymlink,
Reset
} state, next_state;
---------------------------------------
When I remove the __initdata before "enum state", the output is=
the following:
---------------------------------------
init/initramfs.c:35: warning: `__section__' attribute does not=
apply to types
init/initramfs.c: In function `error':
init/initramfs.c:14: `x' undeclared (first use in this function)
init/initramfs.c:14: (Each undeclared identifier is reported only=
once
init/initramfs.c:14: for each function it appears in.)
make[1]: *** [init/initramfs.o] Error 1
---------------------------------------
When I read the init/initramfs.cil.c, I find the following code=
in init/initramfs.c:
------------------------------------------
static __initdata char *message;
static void __init error(char *x)
{
if (!message)
message =3D x;
}
------------------------------------------
has been translated into the following:
------------------------------------------
#line 10 "init/initramfs.c"
static char *message __attribute__((__section__(".init.data"))) =
;
#line 11
static void error(char *m ) =
__attribute__((__section__(".init.text"))) ;
#line 11 "init/initramfs.c"
static void error(char *m )
{
{
#line 13
if (! message) {
#line 14
message =3D x;
}
#line 15
return;
}
}
#line 17
------------------------------------------
It is obvious that: The cil changed the praramter of error from=
"x" to "m" But it SHOULD NOT be changed.
Thanks a lot!
