Allow vector shifts (shl,lshr,ashr) on SPU.

2011-03-04T13:19:18Z

There was a previous implementation with patterns that would have matched e.g. shl , but this is not valid LLVM IR so they never were selected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126998 91177308-0d34-0410-b5e6-96231b3b80d8

Allow load from constant on SPU.

A 'load <4 x i32>* null' crashes llc before this fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126995 91177308-0d34-0410-b5e6-96231b3b80d8

Add branch hinting for SPU.

The implemented algorithm is overly simplistic (just speculate all branches are taken)- this is work in progress. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126651 91177308-0d34-0410-b5e6-96231b3b80d8

Allow targets to specify a the type of the RHS of a shift parameterized on the type of the LHS.

Revert r124611 - "Keep track of incoming argument's location while emitting LiveIns."

In other words, do not keep track of argument's location. The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body. This requires some coordination with debugger to get this working. - The debugger needs to be aware of prolog_end attribute attached with line table entries. - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126155 91177308-0d34-0410-b5e6-96231b3b80d8

clang's -Wuninitialized-experimental warning. While these don't look like real bugs, clang's -Wuninitialized-experimental analysis is stricter than GCC's, and these fixes have the benefit of being general nice cleanups. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124073 91177308-0d34-0410-b5e6-96231b3b80d8
