2014-11-01[mips] Move all ByVal handling into CCState and tablegen-erated code. NFC.Daniel Sanders1-3/+3
Summary: CCState already contains a byval implementation that is very similar to the Mips custom code. This patch merges the custom code into the existing common code and tablegen-erated code.

Rename to allowsMisalignedMemoryAccess. On R600, 8 and 16 byte accesses are mostly OK with 4-byte alignment, and don't need to be split into multiple accesses.

2014-04-30[mips][msa] Fix vector insertions where the index is variableDaniel Sanders1-0/+5
Summary: This isn't supported directly so we rotate the vector by the desired number of elements, insert to element zero, then rotate back. The i64 case generates rather poor code on MIPS32. There is an obvious optimisation to be made in future (do both insert.w's inside a shared rotate/unrotate sequence) but for now it's sufficient to select valid code instead of aborting.

These intrinsics are legalized to V(ALL|ANY)_(NON)?ZERO nodes, are matched as SN?Z_[BHWDV]_PSEUDO pseudo's, and emitted as a branch/mov sequence to evaluate to 0 or 1. Note: The resulting code is sub-optimal since it doesnt seem to be possible to feed the result of an intrinsic directly into a brcond. At the moment it uses (SETCC (VALL_ZERO $ws), 0, SETEQ) and similar which unnecessarily evaluates the boolean twice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189478 91177308-0d34-0410-b5e6-96231b3b80d8
