Assembly matchers for instructions with a two-operand form. ARM is full of these, for example: add {Rd}, Rn, Rm // Rd is optional and is the same as Rn if omitted. The property TwoOperandAliasConstraint on the instruction definition controls when, and if, an alias will be formed. No explicit InstAlias definitions are required. rdar://11255754 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155172 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-19Remove llvm-ld and llvm-stub (which is only used by llvm-ld).Michael J. Spencer
llvm-ld is no longer useful and causes confusion and so it is being removed. * Does not work very well on Windows because it must call a gcc like driver to assemble and link. * Has lots of hard coded paths which are wrong on many systems. * Does not understand most of ld's options. * Can be partially replaced by llvm-link | opt | {llc | as, llc -filetype=obj} | ld, or fully replaced by Clang. I know of no production use of llvm-ld, and hacking use should be replaced by Clang's driver. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155147 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-19Defer some shl transforms to DAGCombine.Jakob Stoklund Olesen
The shl instruction is used to represent multiplication by a constant power of two as well as bitwise left shifts. Some InstCombine transformations would turn an shl instruction into a bit mask operation, making it difficult for later analysis passes to recognize the constsnt multiplication. Disable those shl transformations, deferring them to DAGCombine time. An 'shl X, C' instruction is now treated mostly the same was as 'mul X, C'. These transformations are deferred: (X >>? C) << C --> X & (-1 << C) (When X >> C has multiple uses) (X >>? C1) << C2 --> X << (C2-C1) & (-1 << C2) (When C2 > C1) (X >>? C1) << C2 --> X >>? (C1-C2) & (-1 << C2) (When C1 > C2) The corresponding exact transformations are preserved, just like div-exact + mul: (X >>?,exact C) << C --> X (X >>?,exact C1) << C2 --> X << (C2-C1) (X >>?,exact C1) << C2 --> X >>?,exact (C1-C2) The disabled transformations could also prevent the instruction selector from recognizing rotate patterns in hash functions and cryptographic primitives. I have a test case for that, but it is too fragile. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155136 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-18This reverts a long string of commits to the Hexagon backend. TheseChandler Carruth
commits have had several major issues pointed out in review, and those issues are not being addressed in a timely fashion. Furthermore, this was all committed leading up to the v3.1 branch, and we don't need piles of code with outstanding issues in the branch. It is possible that not all of these commits were necessary to revert to get us back to a green state, but I'm going to let the Hexagon maintainer sort that out. They can recommit, in order, after addressing the feedback. Reverted commits, with some notes: Primary commit r154616: HexagonPacketizer - There are lots of review comments here. This is the primary reason for reverting. In particular, it introduced large amount of warnings due to a bad construct in tablegen. - Follow-up commits that should be folded back into this when reposting: - r154622: CMake fixes - r154660: Fix numerous build warnings in release builds. - Please don't resubmit this until the three commits above are included, and the issues in review addressed. Primary commit r154695: Pass to replace transfer/copy ... - Reverted to minimize merge conflicts. I'm not aware of specific issues with this patch. Primary commit r154703: New Value Jump. - Primarily reverted due to merge conflicts. - Follow-up commits that should be folded back into this when reposting: - r154703: Remove iostream usage - r154758: Fix CMake builds - r154759: Fix build warnings in release builds - Please incorporate these fixes and and review feedback before resubmitting. Primary commit r154829: Hexagon V5 (floating point) support. - Primarily reverted due to merge conflicts. - Follow-up commits that should be folded back into this when reposting: - r154841: Remove unused variable (fixing build warnings) There are also accompanying Clang commits that will be reverted for consistency. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155047 91177308-0d34-0410-b5e6-96231b3b80d8
