I asked if you could make it clearer to people who do not know what this is whether they want to use it.

But people who do not know what it is can assume the wrong things about it. It isn't a great name because of that :-( (It's not as bad as the MIPS ABIs -- an older one is called "new" :-) ) > then ELF ABIv2 is more explanatory about it being an abi change > rather than base elf change, even if it's not the "correct" name. I very much disagree. "ELF ABIv2" is completely meaningless. > If you don't want that then good, I also prefer to just use ELFv2. I Good :-) > think people who change this option can easily look up the name in > toolchain and other docs. Yeah. As long as the defaults are good, whoever blows themselves up has only themselves to blame :-P Segher
