Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131

The TwoAddressInstructionPass takes the machine code out of SSA form by expanding REG_SEQUENCE instructions into copies. It is no longer necessary to rewrite the registers used by a REG_SEQUENCE instruction because the new coalescer algorithm can do it now. REG_SEQUENCE is just converted to a sequence of sub-register copies now. llvm-svn: 169067

MachineCopyPropagation doesn't understand super-register liveness well enough to be able to remove implicit defs of super-registers. This fixes a problem in ARM/2012-01-26-CopyPropKills.ll that is exposed by an future TwoAddressInstructionPass change. The KILL instructions are removed before the machine code is emitted. llvm-svn: 169060

The original patch removed a bunch of code that the SjLjEHPrepare pass placed into the entry block if all of the landing pads were removed during the CodeGenPrepare class. The more natural way of doing things is to run the CGP *before* we run the SjLjEHPrepare pass. Make it so! llvm-svn: 169044

This was found by MSVC10's STL debug mode on a test from the test suite. Sadly std::is_heap isn't standard so there is no way to assert this without writing our own heap verify, which looks like overkill to me. llvm-svn: 168885

If we need to split the operand of a VSELECT, it must be the mask operand. We split the entire VSELECT operand with EXTRACT_SUBVECTOR. llvm-svn: 168883

Allow targets to prefer TypeSplitVector over TypePromoteInteger when computing the legalization method for vectors For some targets, it is desirable to prefer scalarizing <N x i1> instead of promoting to a larger legal type, such as <N x i32>. llvm-svn: 168882

No functional change, just moved header files. Targets can inject custom passes between register allocation and rewriting. This makes it possible to tweak the register allocation before rewriting, using the full global interference checking available from LiveRegMatrix. llvm-svn: 168806

This is a simple, cheap infrastructure for analyzing the shape of a DAG. It recognizes uniform DAGs that take the shape of bottom-up subtrees, such as the included matrix multiplication example. This is useful for heuristics that balance register pressure with ILP. Two canonical expressions of the heuristic are implemented in scheduling modes: -misched-ilpmin and -misched-ilpmax. llvm-svn: 168773

This fixes a hole in the "cheap" alias analysis logic implemented within the DAG builder itself, regardless of whether proper alias analysis is enabled. It now handles this pattern produced by LSR+CodeGenPrepare. %sunkaddr1 = ptrtoint * %obj to i64 %sunkaddr2 = add i64 %sunkaddr1, %lsr.iv %sunkaddr3 = inttoptr i64 %sunkaddr2 to i32* store i32 %v, i32* %sunkaddr3 llvm-svn: 168768

The Target library is not allowed to depend on the large CodeGen library, but the TRI and TII classes provide abstract interfaces that require both caller and callee to link to CodeGen. The implementation files for these classes provide default implementations of some of the hooks. These methods may need to reference CodeGen, so they belong in that library. We already have a number of methods implemented in the TargetInstrInfoImpl sub-class because of that. I will merge that class into the parent next. llvm-svn: 168758
