2010-12-12Fix paths; AutoRegen.sh changes its current working directory to be thePeter Collingbourne
autoconf directory, but these paths need to be relative to the main source directory. Patch originally by Dan Gohman, r67655. Also, cause configure.ac to find absolute paths to LLVM source and object trees. Together, fixes PR1220. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121645 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-121. Change MBlaze indirect branches to use absolute branch BRALD instead of ↵Wesley Peck
pc relative branch BRLD. 2. Make sure that the MBlaze stack is aligned to 4-byte boundaries. 3. Determine frame indexes that should be placed in the callers stack frame, as per the MBlaze ABI, and place them in the correct locations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121639 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-10Force the greedy register allocator to always use the inline spiller.Jakob Stoklund Olesen
Soon, RegAllocGreedy will start splitting live ranges, and then deferred spilling won't work anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121591 91177308-0d34-0410-b5e6-96231b3b80d8

AliasAnalysis consumers, PartialAlias will be treated as MayAlias. For AliasAnalysis chaining, MayAlias says "procede to the next analysis".
