[Bug target/34299] New: [avr] ICE on function attribute syntax for main()

+++ This bug was initially created as a clone of Bug #31331 +++

On a Mac(Tiger) compilation of a TinyOS standard example application "Blink"
does not compile. Please mail me if important information is missing. As I
cannot access the MAC I cannot provide the C file created by the Nesc Compiler.

The subject line of this bug is the same subject as bug #31331, which is fixed.
Without having the preprocessed source it is difficult to determine if this bug
is a duplicate.

------- Comment #3 from j at uriah dot heep dot sax dot de  2008-01-10 15:56 -------
Some bugs appear to re-appear. :-(

While I get

__attribute__((naked))
int main(void)
{
  // ...
   return 42;
}

to compile with the current compiler, the following piece of code:

__attribute__((signal, naked))
void __vector_42(void)
{
   static unsigned char x;

   x++;
}

still triggers the ICE:

% avr-gcc -mmcu=attiny2313 -S foo.c
foo.c:3: internal compiler error: in start_function, at c-decl.c:6177

> void __vector_42(void)
> {
>    static unsigned char x;
> 
>    x++;
> }
> 
> still triggers the ICE:


However, if there is a function prototype, and the attributes are placed on the
prototype, there is no bug:

__attribute__((signal, naked))
void __vector_42(void);

void __vector_42(void)
{
   static unsigned char x;

   x++;
}

Is it really a bug?

Sorry for the dup.

This bug prevents compilation of almost all TinyOS apps using 4.3.3!  Is there
a workaround?

Created an attachment (id=17370)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=17370&action=view)
patch for bug 34299

DECL_ASSEMBLER_NAME has a side effect of setting assembler_name for functions
if that attribute is missing, which causes the assertion failure in c-decl.c.

Change it to less harmful DECL_NAME.
