Ping ? Do you think that we need to have an API in LinkingContext to return the next ordinal available, so that files created by passes can be assigned ordinals ?

...like the the ELFPassFile doesnot get an ordinal value assigned, as its added in a pass. Is there a way to assign a file ordinal for the files added by Passes ? Till that time, I am going to XFAIL the ifunc test. More tests should fail, and am not sure why they are not failing.

The method to identify functions with in-class definitions is one part of my question. Even if there is a way to do that without passing the hint, I'm interested in getting feedback on treating it at-par with functions having the inline hint in inline cost analysis.

...the filename in the Atom as the native format needs to store that information. The only option for the ELF writer to know this information is to use References if other flavors dont need the filename (only in DEBUG mode, clumsy but would work).

In addition I think the LayoutPass std::stable_sort be replaced with std::sort as total ordering is guaranteed as each File would get an ordinal and each atom would get an ordinal too, after the below problem is fixed.

The --as-needed attribute is preserved and is contained within the ELF FileNode. By lld::files, I am referring to lld::File.

Yes, the Group is to represent --start-group,--end-group. So the group here will be contained in the linker Input as a vector of lld::files (foo.a, bar.a). thanks Shankar Easwaran On 9/4/2013 3:59 PM, Rui Ueyama wrote: > The first question is that Group is to represent --start-group/--end-group? > > If I understand your proposal correctly, here's the thing: if file is not > in group, each individual file is wrapped with LinkerInput, but if it's in > a...

...ase is just one example of it. I have also seen similiar code in http://lxr.free-electrons.com/source/arch/powerpc/kernel/head_32.S?a=powerpc which has global and local labels. You are right, that the function has multiple entry points. You can remove the .local directive too. Thanks Shankar Easwaran On 11/15/2012 9:47 PM, Nick Kledzik wrote: > Shankar, > > Let's step back.
