...entially. To be more precise I'm saying that TargetMachine (or an MC level equivalent > - see TargetSubtargetInfo/MCSubtargetInfo) should encapsulate everything that's needed > from the object level down for any particular target. That sounds like TargetTuple but spelt something like MCTargetMachine. It sounds like MCTargetMachine should usurp the Triple in the places it exists in the MC layer (and maybe be introduced to a few new portions of it) and accurately reflect the desired target just like in the later stages of the TargetTuple plan intended. The main difference I see is small a small...

Hi all, Thank you so much for this discussion. It has been very helpful and educational. I think that I understand the perspectives of both Tim and Renato. Let me briefly summarize them to ensure that I correctly understand: Renato’s perspective is that the triple means whatever the author says it does, and that may or not be meaningful. :) In the case of armv7l (for example) it has a clear

...is needed because it appears in a path. Whatever uses triple today would then consult individual pieces of information in the TargetMachine instead. (As before I don’t think we need dwell on this here though but instead begin discussion about enhancing TargetMachine to start with and then inventing MCTargetMachine.)

...not the ABI (which is currently unavailable to the relevant object). I have three patches that make a start on a general solution for this kind of problem (http://reviews.llvm.org/D13858, http://reviews.llvm.org/D13860, and http://reviews.llvm.org/D13863). The overall intent is that we create an MCTargetMachine that describes the desired target (taking into account the default ABI for the triple and any options that change it) and use it as a factory for the MC layer objects. This way we can pass relevant detail down to the MC objects without having to have all targets agree on what information should be...

I am implementing a defined, but currently unimplemented by LLVM, ABI. This ABI differs from an existing ABI in its ELF object format by implementing a subset of an existing ABI, but encoded differently and by setting the e_ident EI_CLASS field. I am trying to use MCTargetOptions::getABIName to set a boolean in the modified subclass of MCELFObjectTargetWriter to indicate which relocation encoding
