2006-08-25Add an assertion to check that we're really preserving LCSSA.Owen Anderson

2006-08-25Encode pc-relative conditional branch offset as pc+(num of bytes / 4). TheEvan Cheng
asm printer will print it as offset*4. e.g. bne cr0, $+8. The PPC code emitter was expecting the offset to be number of instructions, not number of bytes. This fixes a whole bunch of JIT failures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29885 91177308-0d34-0410-b5e6-96231b3b80d8

Final commit for this bug. This removes the last EH holdouts in LLVM and turns off exception support by using the -fno-exceptions option.

2006-08-24Take advantage of the recent improvements to the liveintervals set (trackingChris Lattner
instructions which define each value#) to simplify and improve the coallescer. In particular, this patch: 1. Implements iterative coallescing. 2. Reverts an unsafe hack from handlePhysRegDef, superceeding it with a better solution. 3. Implements PR865, "coallescing" away the second copy in code like: A = B ... B = A This also includes changes to symbolically print registers in intervals when possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29862 91177308-0d34-0410-b5e6-96231b3b80d8

2006-08-23Make the ProgramName variable a std::string so we can eliminate the pathReid Spencer
portion fo the program name via sys::Path().getLast(). This makes error messages more readable since this is invariably used only in error messages. Instead of: /path/to/llvm/bin/directory/toolname: error message we will now get: toolname: error message Also, since we always have a program name (even if its defaulted), don't check to see if it is set or not when generating error messages. This eliminates a bunch of constant strings, saving a little under 1K of data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29842 91177308-0d34-0410-b5e6-96231b3b80d8
