Isn't this a matter to take up further in the thread HJ started on the ABI mailing lists, or a new such thread (possibly e.g. sending pull requests that build further on his wording, or propose alternative wording, to clarify them things left unclear there, with a goal of getting it clearly defined in the master sources for x86_64 and x86)? Clearly the best result would be proper documentation in the ABI and the GCC manual cross-referencing the relevant ABI documents. -- Joseph S. Myers jos...@codesourcery.com
