* CollectorMetadata abstractly describes stack maps for a function.Gordon Henriksen2007-09-271-0/+195
| | | | | | | | | | | | | | | | | | | | It includes: - location and of each safe point in machine code (identified by a label) - location of each root within the stack frame (identified by an offset), including the metadata tag provided to llvm.gcroot in the user program - size of the stack frame (for collectors which want to cheat on stack crawling :) - and eventually will include liveness It is to be populated by back-ends during code-generation. CollectorModuleMetadata aggregates this information across the entire module. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42418 91177308-0d34-0410-b5e6-96231b3b80d8

* - Added MRegisterInfo::getCrossCopyRegClass() hook. For register classes ↵Evan Cheng2007-09-261-0/+13
| | | | | | | | | where reg to reg copies are not possible, this returns another register class which registers in the specified register class can be copied to (and copy back from). - X86 copyRegToReg() now supports copying between EFLAGS and GR32 / GR64 registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42372 91177308-0d34-0410-b5e6-96231b3b80d8

The BURR scheduler can now backtrace and duplicate instructions in order to avoid "expensive / impossible to copy" values (e.g. status flag EFLAGS for x86) from being clobbered. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42284 91177308-0d34-0410-b5e6-96231b3b80d8

* Factor the dominator tree calculation details out into ↵Owen Anderson2007-09-232-16/+14
| | | | | | | | | | | | | | DominatorCalculation.h. This change is not useful in and of itself, but it lays the groundwork for combining the dominator and postdominator implementations. Also, factor a few methods that are common to DominatorTree and PostDominatorTree into DominatorTreeBase. Again, this will make merging the two calculation methods simpler in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42248 91177308-0d34-0410-b5e6-96231b3b80d8

* Previously GraphWriter assumed operator*() for node_iterator alwaysTed Kremenek2007-09-191-1/+5
| | | | | | | | | | | | | | returned a reference type. This patch allows operator*() to return a non-reference type while still maintaining the old behavior when it does return a reference type. This patch was motivated when I tried to use "df_iterator" (see llvm/ADT/DepthFirstIterator.h) as a "node_iterator", as df_iterator does not return a reference type and thus we would get a compilation error when trying to take the address of a temporary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42151 91177308-0d34-0410-b5e6-96231b3b80d8

* C bindings for libLLVMCore.a and libLLVMBitWriter.a.Gordon Henriksen2007-09-181-0/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | - The naming prefix is LLVM. - All types are represented using opaque references. - Functions are not named LLVM{Type}{Method}; the names became unreadable goop. Instead, they are named LLVM{ImperativeSentence}. - Where an attribute only appears once in the class hierarchy (e.g., linkage only applies to values; parameter types only apply to function types), the class is omitted from identifiers for brevity. Tastes like methods. - Strings are C strings or string/length tuples on a case-by-case basis. - APIs which give the caller ownership of an object are not mapped (removeFromParent, certain constructor overloads). This keeps keep memory management as simple as possible. For each library with bindings: llvm-c/<LIB>.h - Declares the bindings. lib/<LIB>/<LIB>.cpp - Implements the bindings. So just link with the library of your choice and use the C header instead of the C++ one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42077 91177308-0d34-0410-b5e6-96231b3b80d8
