I was hoping I'd have the new debug info infrastructure, based on annotations carried all the way from the source code, ready in time. Even though I already have code to introduce the annotations in the tree representation, only when generating debug information, and to carry them over all the way to rtl var-tracking, without any changes whatsoever to the generated code on x86_64-linux-gnu. I have already written (over this past weekend) some code in var-tracking to use these annotations to generate improved debug info notes, but this last part still needs some work. I think it would be nice to offer this new debug info generation machinery, at least as an option, in GCC 4.3, so I'd like to request some more time to make it fully functional before I post the very large patches. Making it optional and disabled by default would make it very non-intrusive and safe for stage3, in spite of the patch size, and would enable a wider audience to give it a try and report problems and opportunities for improvement. I'm already aware of many of these, but I'm not yet at a point in which I can compare the quality of the generated debug info. -- Alexandre Oliva http://www.lsd.ic.unicamp.br/~oliva/ FSF Latin America Board Member http://www.fsfla.org/ Red Hat Compiler Engineer [EMAIL PROTECTED], gcc.gnu.org} Free Software Evangelist [EMAIL PROTECTED], gnu.org}
