--- Comment #97 from The Written Word <bugzilla-gcc at thewrittenword dot com> --- (In reply to C. Heide from comment #73) > With that change, and some other cajoling (the previously mentioned > duplicate symbols and operand64 problem, and -O1 to work around the ICE), I > can now get gcc-8.3 to do a full bootstrap on HP-UX 11.23 ia64. No issues with PCH or libsupc++ like I'm seeing?
