--- Comment #1 from Mikael Pettersson <mikpe at it dot uu.se> 2011-04-05 22:30:36 UTC ---
I can easily reproduce the ICE with gcc-4.4.5 and 4.5.2 targeting
arm-linux-gnueabi, using the command line
gcc -O1 -S test.i
-mcpu= etc options don't seem to make any difference.
gcc-4.3.5 works. Haven't been able to check 4.6.0 yet because there the test
case triggers errors in code that isn't valid C1X.

reduced test case
The test case reduces to the following:
void __attribute__((naked)) f(void)
{
int x = 0;
g(&x);
}
It ICEs 4.4.5, 4.5.2, and 4.6.0, but not 4.3.5, 4.2.4, or 4.1.2.
I suspect it isn't valid to make recursive calls or take the address of local
variables in naked functions.

It is important to note, however, that the original test case does not take the
address of a local variable in a naked function. The original test case is like
this:
static void g(void);
void __attribute__((naked)) f(void)
{
g();
}
void g(void)
{
int x = 0;
h(&x);
}
So this may be due to overzealous inlining.
