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 ?

...to store 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).

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...

Standard error is what many tools, including clang for example, use for their --verbose output. This is appropriate because it leaves standard output available for regular output data, which the user may wish to capture in a file or a pipe.
