2017-05-31[PowerPC] Eliminate integer compare instructions - vol. 2Nemanja Ivanovic
This patch builds upon https://reviews.llvm.org/rL302810 to add handling for bitwise logical operations in general purpose registers. The idea is to keep the values in GPRs as long as possible - only extracting them to a condition register bit when no further operations are to be done.

This is the equivalent of r304048 for ARM: - Rewrite livein calculation to use the computeLiveIns() helper function.

2017-05-30[CodeView] Move CodeView YAML code to ObjectYAML.Zachary Turner
This is the beginning of an effort to move the codeview yaml reader / writer into ObjectYAML so that it can be shared. Currently the only consumer / producer of CodeView YAML is llvm-pdbdump, but CodeView can exist outside of PDB files, and indeed is put into object files and passed to the linker to produce PDB files. Furthermore, there are subtle differences in the types of records that show up in object file CodeView vs PDB file CodeView, but they are otherwise 99% the same. By having this code in ObjectYAML, we can have llvm-pdbdump reuse this code, while teaching obj2yaml and yaml2obj to use this syntax for dealing with object files that can contain CodeView. This patch only adds support for CodeView type information to ObjectYAML. Subsequent patches will add support for CodeView symbol information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@304248 91177308-0d34-0410-b5e6-96231b3b80d8

2017-05-30[LV] Reapply r303763 with fix for PR33193Matthew Simpson
r303763 caused build failures in some out-of-tree tests due to an assertion in TTI. The original patch updated cost estimates for induction variable update instructions marked for scalarization. However, it didn't consider that the incoming value of an induction variable phi node could be a cast instruction. This caused queries for cast instruction costs with a mix of vector and scalar types. This patch includes a fix for cast instructions and the test case from PR33193. The fix was suggested by Jonas Paulsson <paulsson@linux.vnet.ibm.com>.

2017-05-30[Cloning] Take another pass at properly cloning debug infoKeno Fischer
Summary: In rL302576, DISubprograms gained the constraint that a !dbg attachments to functions must have a 1:1 mapping to DISubprograms. As part of that change, the function cloning support was adjusted to attempt to enforce this invariant during cloning. However, there were several problems with the implementation. Part of these were fixed in rL304079. However, there was a more fundamental problem with these changes, namely that it bypasses the matadata value map, causing the cloned metadata to be a mix of metadata pointing to the new suprogram (where manual code was added to fix those up) and the old suprogram (where this was not the case). This mismatch could cause a number of different assertion failures in the DWARF emitter. Some of these are given at https://github.com/JuliaLang/julia/issues/22069, but some others have been observed as well. Attempt to rectify this by partially reverting the manual DI metadata fixup, and instead using the standard value map approach. To retain the desired semantics of not duplicating the compilation unit and inlined subprograms, explicitly freeze these in the value map.
