Hi, 've reworked the AIX driven patches based on the discussion around patch "[3/4] Use POSIX nm to simplify AIX export_symbols_cmds." http://lists.gnu.org/archive/html/libtool-patches/2016-03/msg00016.html
Previous patch "[1/4] Fix func_echo_all inside configure." is not required any more, although it still makes sense to be committed. Previous patch "[2/4] AIX: Do not rely on OBJECT_MODE env var being set." now is "[1/3] AIX: use proper ABI flags in search for toolchain" and requires the gnulib patch "early check for PowerPC AIX object mode", http://lists.gnu.org/archive/html/bug-gnulib/2016-03/msg00046.html although that one still is waiting for attention by gnulib developers. Previous patch "[3/4] Use POSIX nm to simplify AIX export_symbols_cmds." now is "[2/3] support POSIX nm, prefer POSIX nm for AIX", and addresses Peter's concerns in above discussions: * respect the user provided NM value * work with (user provided) NM (even without BSD- or POSIX-flag) * more strictly check for nm's POSIX interface * emit a warning when the user provided NM fails to mark weak symbols And finally, patch "AIX: Stop exporting any _GLOBAL__ symbol." still applies for more robust g++ exception handling. Indeed the patches feel more straightforward now. Thanks for reconsideration! /haubi/
