[RFC] Adding function attributes to represent codegen optimization level
...e intent of these attributes are to control the codegen pipeline only. Of course this is all based on the assumption that using the optimization level used during bitcode generation should also be used with LTO in the codegen pipeline. I don't have a strong opinion either way. I just want codgen to respect the fact that I specified -O3 during both the bitcode generation and link steps, but that's not the case anymore. :) Chad > > Thanks, > > -- > Mehdi > >> Assuming the argument is reasonable (it make sense to me), I was >> hoping >> to sol...

The change now causes the codegen optimization > level to default to CodeGenOpt::Default (i.e., -O2) rather than use the > LTO optimization level. The argument was made that the LTO
