...ot sure why we have things split into three separate pages: * TableGen - http://llvm.org/docs/TableGen/index.html * Introduction - http://llvm.org/docs/TableGen/LangIntro.html * Reference - http://llvm.org/docs/TableGen/LangRef.html I consistently find myself lost between those pages. -- Meador

Hi Meador, I couldn't reproduce the ASan failures on my 10.8 machine (trying that on a 10.7 one now) I'll look into making the in-process symbolizer work on OSX (which should fix some of the ubsan failures), but we do not need it in production currently, so I'm not sure when I get to it. On Mon...

Hello all, I don't find anything helping me understand the llvm bang operator. In the llvm TableGen language reference, it only says: 'TableGen also has “bang operators” which have a wide variety of meanings: *'* I would be very thankful if someone can explain it to me. e.g. what does "!strconcat" or "!if" mean?

...lifyFortifiedLibCalls` to go away as well, since the fortified library call folding is being rolled into `LibCallSimplifier`. I will look at applying `LibCallSimplifier` to the CGP case as well (the conditions for when it is OK to fold is slightly different for CGP).
