From: Janis Johnson To: schnetter@uni-tuebingen.de Cc: gcc-gnats@gcc.gnu.org Subject: Re: web/10254: Explain binary compatibility to other vendors' compilers Date: Fri, 28 Mar 2003 14:38:13 -0800 Information about binary compatibility between GCC and other compilers would be useful, but a page keeping track of such information could get messy very quickly. The information itself could become outdated when new versions of compilers are released, and links like this are difficult to keep up to date. There's another problem with providing links to information about other compilers. I looked up a particular compiler to see if it had a statement about binary compatibility with GCC; it does, but it follows a claim about how easy it is to port code from using GCC to using that proprietary compiler. Links to that kind of information aren't appropriate for the GCC site. It would be appropriate, though, for us to describe known incompatibilities or ABI corner cases, along with examples that demonstrate how real code is affected. I've been planning to add more of such examples as test cases in testsuite/g++.dg/compat/abi (feel free to nag me about that). Those tests (once they exist!) could be mentioned in the Binary Compatibility section of the GCC Manual. Erik, does that sound reasonable? Janis Johnson janis187@us.ibm.com
