Thanks for the suggestion. If there is opposition to adding support for dynamic symbols, then I will try the assembly+linker approach, but if I can add the support for dynamic symbols, then I'll continue with yaml2obj, at least for now. We also had a test case we wanted to write using obj2yaml but couldn't because of the lack of dynamic symbols.</span></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Nov 1, 2017 at 12:40 PM, Rui Ueyama <span dir="ltr"><<a href="mailto:ruiu@google.com" target="_blank">ruiu@google.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><span class="">On Wed, Nov 1, 2017 at 11:56 AM, Dave Lee <span dir="ltr"><<a href="mailto:davelee.com@gmail.com" target="_blank">davelee.com@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><span>> <span style="font-size:12.800000190734863px">I wonder why you want to add the new feature to yaml2obj.

I'm seeking opinions about how to model dynamic symbols (and symbols in general) in the yaml structure. Currently, symbols in elf are represented by a top level `Symbols` key, within which symbols are grouped by binding type (Global, Weak, Local). The simplest thing to do would be to mirror this structure to a DynamicSymbols (or SymbolsDynamic). Is there other ways people would like to see this structure represented? Saleem suggested symbols be modeled more closely to the elf spec, and that the binding type should be represented as an attribute on each symbol, not as a grouping. For comparison, coff and macho both appear to represent the file format more directly, without much (any?) added abstraction.<div><br></div><div>Short pseudo example of the current symbol structure:<br><div><div><br></div><div> Symbols:</div><div> Global:</div><div> - Name: ...</div><div> Type: ...</div><div> Section: ...</div><div><div> ...</div><div> Weak:</div><div> - Name: ...</div><div> Type: ...</div><div> Section: ...</div></div><div> ...</div><div> Local:<br></div><div><div> - Name: ...</div><div> Type: ...</div><div> Section: ...</div></div><div><div> ...</div></div><div><br></div></div></div><div>thanks,</div><div>Dave</div></div>
