* The vpermilps and vpermilpd have different behaviour regarding theBruno Cardoso Lopes2011-07-275-32/+156
| | | | | | | | | usage of the shuffle bitmask. Both work in 128-bit lanes without crossing, but in the former the mask of the high part is the same used by the low part while in the later both lanes have independent masks. Handle this properly and and add support for vpermilpd. llvm-svn: 136200

* Add support for multi-way live range splitting.Jakob Stoklund Olesen2011-07-261-64/+165
| | | | | | | | | | | | | | | | | | | | | When splitting global live ranges, it is now possible to split for multiple destination intervals at once. Previously, we only had the main and stack intervals. Each edge bundle is assigned to a split candidate, and splitAroundRegion will insert copies between the candidate intervals and the stack interval as needed. The multi-way splitting is used to split around compact regions when enabled with -compact-regions. The best candidate register still gets all the bundles it wants, but everything outside the main interval is first split around compact regions before we create single-block intervals. Compact region splitting still causes some regressions, so it is not enabled by default. llvm-svn: 136186

* Eliminate copies of undefined values during coalescing.Jakob Stoklund Olesen2011-07-263-0/+80
| | | | | | | | | | These copies would coalesce easily, but the resulting value would be defined by a deleted instruction. Now we also remove the undefined value number from the destination register. This fixes PR10503. llvm-svn: 136174

* Add a neat little two's complement hack for x86.Benjamin Kramer2011-07-263-28/+49
| | | | | | | | | | On x86 we can't encode an immediate LHS of a sub directly. If the RHS comes from a XOR with a constant we can fold the negation into the xor and add one to the immediate of the sub. Then we can turn the sub into an add, which can be commuted and encoded efficiently. This code is generated for __builtin_clz and friends. llvm-svn: 136167

* ARM rot_imm printing adjustment.Jim Grosbach2011-07-263-9/+9
| | | | | | | Allow the rot_imm operand to be optional. This sets the stage for refactoring away the "rr" versions from the multiclasses and replacing them with Pat<>s. llvm-svn: 136154
* ARM cleanup of rot_imm encoding.Jim Grosbach2011-07-268-44/+47
| | | | | | | | Start of cleaning this up a bit. First step is to remove the encoder hook by storing the operand as the bits it'll actually encode to so it can just be directly used. Map it to the assembly source values 8/16/24 when we print it. llvm-svn: 136152
