2008-04-07Rename MemOperand to MachineMemOperand. This was suggested byDan Gohman
review feedback from Chris quite a while ago. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49348 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-07Add operator= implementations to SparseBitVector, allowing it to be used in ↵Owen Anderson
GVN. This results in both time and memory savings for GVN. For example, one testcase went from 10.5s to 6s with this patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49345 91177308-0d34-0410-b5e6-96231b3b80d8

needs to be fixed here - a previous commit made sure that intrinsics always get the right attributes.

2008-04-03- PHI elimination also eliminates implicit_def that fits into a PHI node ↵Evan Cheng
rather than copying it. - Be (slightly) smarter about where to place the copies. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49165 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-03Start of a series of patches related to implicit_def.Evan Cheng
There is no point in creating a long live range defined by an implicit_def. Scheduler now duplicates implicit_def instruction for each of its uses. Therefore, if an implicit_def node has multiple uses, it will become a number of very short live ranges, rather than a long one. This will make coalescer's job easier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49164 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-03Re-implemented Path::createDirectoryOnDisk (for Unix).Ted Kremenek
This method allows one to create a directory, and optionally create all parent directories that do not exist. The original implementation would require that *all* directories along a path are writable by the user, including directories that already exist. For example, suppose we wanted to create the directory "/tmp/foo/bar", and the directory "/tmp" already exists, but not "/tmp/foo". Since "/tmp" is writable by all users, the original implementation would work, and create "/tmp/foo", followed by "/tmp/bar". A problem occurred, however if one wanted to created the directory "/Users/myuser/bar" (or equivalently "/home/myuser/bar"), and "/Users/myuser" already existed and is writable by the current user. The directory "/User/myuser" is writable by the user, but "/User" is not. The original implementation of createDirectoryOnDisk would return with failure since "/User" is not writable, even though "/User/mysuser" is writable. The new implementation works by recursively creating parents as needed, and thus doesn't need to check the permissions on every directory in a path. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49162 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-02Recommitting EH patch; this should answer most of theDale Johannesen
review feedback. -enable-eh is still accepted but doesn't do anything. EH intrinsics use Dwarf EH if the target supports that, and are handled by LowerInvoke otherwise. The separation of the EH table and frame move data is, I think, logically figured out, but either one still causes full EH info to be generated (not sure how to split the metadata correctly). MachineModuleInfo::needsFrameInfo is no longer used and is removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49064 91177308-0d34-0410-b5e6-96231b3b80d8
