Hi! While testing --with-aix-soname=[aix|both|svr4] libtool patches within gcc, I've discovered that gcc does not set OBJECT_MODE during multilib build. Instead, the only settings done are: CC='xgcc -maix64' CXX='xg++ -maix64', besides AR="$AR -X32_64" NM="$NM -X32_64" - which feels like a workaround anyway and would be necessary for LD, STRIP and RANLIB too.
However, I've found some ABI-specific LD-flags settings in _LT_ENABLE_LOCK, but that would be too late for checking "the name lister ($NM) interface". Besides that, _LT_ENABLE_LOCK feels suboptimal anyway as the place to set the ABI-specific tool flags based on created object's file type. So I would like to introduce _LT_SET_TOOL_ABI_FLAG(TOOL, [TOOLVAR]) macro (patch 2/2), doing something useful for power*-*-aix* for now, but designed to adopt similar settings from _LT_ENABLE_LOCK by subsequent refactorings. Thanks! /haubi/
