I am seeing this slow compile too. It compiles OK on HPPA in 32 bit mode (1.5
minutes) but takes over 30 minutes in 64 bit mode. It also takes 6+ minutes on
IA64 HP-UX. On an X86 box it took less than 1 minute.
Using gprof on HPPA 64 bit mode I see 2.6 Billion (2614726712) calls to
loc_mentioned_in_p. I think most are coming from remove_address_replacements
but I am still trying to understand the problem.
