=== PROBLEM === (See this bug https://llvm.org/bugs/show_bug.cgi?id=26445) IR contains code for loading a float from float * and storing it to a float * address. After canonicalization of load in InstCombine [1], new bitcasts are added to the IR (see bottom of the email for code samples). This prevents select speculation in SROA to work. Also after SROA we have bitcasts...

I seem to be having a problem working with an object which has a HABTM relationship with another object I know there''s been a lot of talk recently about problems using dual HABTM in a single object but I believe this may be a separate issue. It appears like I''m unable to persist this relationship (i.e. the object saves but none of the entries in the join table are

Sorry for my delay responding, finally caught up on my email to this point and read through the whole thread. First and foremost: we should *definitely* not sit on our hands and wait for typeless pointers to arrive. However, we also shouldn't (IMO) take on lots of technical debt instead of working on causing typeless pointers to arrive sooner. But I don't think any of the options here are

OK. I will do some experiments with (1) on Power PC. Will update this email chain about the results. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20160323/f05c1bad/attachment.html>
