[LLVMdev] [lld][failing test] the reason of ifunc.test failing
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 ?

[LLVMdev] Inline hint for methods defined in-class
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.

[LLVMdev] [lld][failing test] the reason of ifunc.test failing
...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.

[LLVMdev] [lld] filename in the atom model.
...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).

...t. 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.

[LLVMdev] [lld] Modeling ELF FileNodes/ControlNodes (Group's) in lld
Yes, the Group is to represent --start-group,--end-group.
