I am looking at an lto bug on ia64-hp-hpux11.23. If I compile g++.dg/torture/pr33572.C with -flto on this platform I get:
ld: Unsatisfied symbol "__gcc_personality_v0" in file /var/tmp//ccYlpGzO.ltrans0.ltrans.o 1 errors. collect2: ld returned 1 exit status (This is using the HP linker which I do for all my GCC builds.) If I add -flto-partition=none to the link, then everything works fine. I notice that the =none option fo -flto-partition does not seem to be documented in invoke.texi, which only covers 1to1 and balanced so I am not sure what it means (put everything in one object?). In both cases if I look at the output of the linker I see an undef of __gcc_personality_v0 in the object file created by compiling pr33572.C and a definition that should resolve that use in libstdc++.so. libstdc++.so is searched in both cases and __gcc_personality_v0 is found in both cases so I don't understand why I am getting the error in the standard -flto case. Does anyone have any ideas on what I should look at to understand this problem? I get this on a few other -flto programs, but not on all of them. Steve Ellcey s...@cup.hp.com
