If you do not need to enable IPA, the whole ld-new and other IPA related stuffs ( all files in osprey/ipa ) can be ignored.
If IPA is needed, the ld-new must be migrated because the system ld does not know WHIRL related sections at all. The ld-new ( osprey/cygnus ) is based on gnu binutils-2.16.1. I do know if gnu ld is compatible with the OpenSolaris ld. But it should not be trouble because the output of ld-new will be fed into Open64 backend. Then the Open64 driver will call the system ld to do the final linking. 2009/3/6 Rayson Ho <raysonlogin at gmail.com> > Jian-Xin: > > Is there anything modified in "ld-new"??
