* Reorganize llvmc code.Mikhail Glushenkov2009-03-027-1/+789
| | | | | | | | | | Move the code from 'llvmc/driver' into a new CompilerDriver library, and change the build system accordingly. Makes it easier for projects using LLVM to build their own llvmc-based drivers. Tested with objdir != srcdir. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65821 91177308-0d34-0410-b5e6-96231b3b80d8

Try harder to create a legal build_vector type. Note: this will be totally irrelevant once vector_shuffle no longer takes a build_vector for shuffle mask.

* Another sentinel optimization. This one should alwaysGabor Greif2009-03-011-7/+0
| | | | | | be a win, since almost every interesting function has at least one Argument. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65778 91177308-0d34-0410-b5e6-96231b3b80d8
* Reuse a technique (pioneered for BasicBlocks) of superposing ilist withGabor Greif2009-03-011-7/+0
| | | | | | | | | | | | | its sentinel. This is quite a win when a function really has a basic block. When the function is just a declaration (and stays so) the old way did not allocate a sentinel. So this change is most beneficial when the ratio of function definition to declaration is high. I.e. linkers etc. Incidentally these are the most resource demanding applications, so I expect that the reduced malloc traffic, locality and space savings outweigh the cost of addition of two pointers to Function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65776 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a long-standing bug and misfeature of the disassembler: when dealing with a Chris Lattner2009-03-011-12/+122
| | | | | | | | | | | | | | | stripped .bc file, it didn't make any attempt to try to reuse anonymous types. This causes an amazing type explosion due to types getting duplicated everywhere they are referenced and other problems. This also caused correctness issues, because opaque types are unique for each time they are uttered in the file. This means that stripping a .bc file could produce a .ll file that could not be assembled (e.g. 2009-02-28-StripOpaqueName.ll). This patch fixes both of these issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65738 91177308-0d34-0410-b5e6-96231b3b80d8
