There seem to be different, conflicting implementations of
size_of_encoded_value():
dwarf2asm.c-int
dwarf2asm.c:size_of_encoded_value (int encoding)
unwind-pe.h-static unsigned int
unwind-pe.h:size_of_encoded_value (unsigned char encoding)

I suppose the static function
static const unsigned char *
read_uleb128 (const unsigned char *p, _uleb128_t *val)
{
in unwind-pe.h should be marked 'inline', otherwise it will be emitted
multiple times to the asm file by -combine.

The static size_of_encoded_value's are supposed to be mangled when --combine,
like size_of_encoded_value.12521 and on a simple testcase with --combine
on x86_64-linux/trunk they are.

Confirmed. The following also fails with optimization:
t1.c:
static void __attribute__((used))
size_of_encoded_value (void)
{
};
static int __gthrw_pthread_once __attribute__ ((__weakref__("pthread_once")));
t2.c:
void size_of_encoded_value (void)
{
};
Not a regression.

unwind-pe.h as a header should provide an interface to and not implementations
of the required functions. Apart from fixing the functions in IMA, unwind-pe.h
should split it's implementations off into a e.g. unwind-pe.c that exports the
common helpers.
Does somebody know if it is really intended that dwarf2asm.c has grown (or
kept) a different impl of size_of_encoded_value() than all the rest?

Works flawlessly for me (without the static, on debian with the debian-patched
cc):
$ gcc-4.1 pr35034-1.c pr35034-2.c -O0 -c -o foo.o -combine -pipe ; echo $?
