- Subject: Constructors/Destructors on hppa64-hp-hpux11
Constructors and destructors were not being run for the dependencies
of dynamic objects. We need to define LDD_SUFFIX and PARSE_LDD_OUTPUT,
or possibly LD_INIT_SWITCH and LD_FINI_SWITCH. Using LDD_SUFFIX and
PARSE_LDD_OUTPUT works with both the HP and GNU linkers, so that's the
approach I adopted. This patch is an interim fix until the linker
issues with using .init/.fini sections are resolved.
Tested on hppa64-hp-hpux11.11. There were no regressions. It fixes
several hundred objc FAILs.
Applied to main.
