[LLVMdev] .thumb_set
For what it is worth it, gas has this strange behaviour. I agree it is strange, but why is it an issue for r239440? Will I get a failure if I revert it?

Is MCRelocationInfo::createExprForRelocation used out of tree?
Hi all The virtual method MCRelocationInfo::createExprForRelocation doesn’t appear to have any callers. Is anyone using it out of tree? In tree, its overridden in X86ELFRelocationInfo.cpp and X86MachORelocationInfo.cpp, but those overrides have 0% coverage (http://llvm.org/reports/coverage/lib/Target/X86/MCTargetDesc/X86MachORelocationInfo.cpp.gcov.html) I’d like to delete these methods and

[LLVMdev] .thumb_set
Hi all Saleem, in 2014 you added the .thumb_set test case. I’ve found a difference in behaviour of .thumb_set compared to .set. I was hoping to resolve this difference as it will allow me to reapply r239440. The issue i’m seeing is that we define an alpha function, then beta function, then assign alpha to beta. But given that beta has already been defined, this would mean we are redefining it

[LLVMdev] RFC: Missing canonicalization in LLVM
...rticular example, I could catch the case of only load -> store. However, there are other stores that use the alloca address, but it is not readily apparent if they come directly & only from a load. Still trying to figure out the best way forward.

Our tutorials, specifically, are in C++, not in C. We could break the C API and we'd likely remain unaware for quite awhile. I think this is the most important point, that we lack testing for it.
