2007-02-08As Chris and Reid suggested, remove "isSigned" field from APInt, instead,Zhou Sheng
add some signed/unsigned arithmetic operation functions into APInt.h to handle the signed/unsigned issue. These functions will be defined inside a namespace "APIntOps" which is inside llvm namespace. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34053 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-08Fixed a long standing spiller bug that's exposed by Thumb:Evan Cheng
The code sequence before the spiller is something like: = tMOVrr %reg1117 = tMOVrr %reg1078 = tLSLri %reg1117, 2 The it starts spilling: %r0 = tRestore <fi#5>, 0 %r1 = tRestore <fi#7>, 0 %r1 = tMOVrr %r1<kill> tSpill %r1, <fi#5>, 0 %reg1078 = tLSLri %reg1117, 2 It restores the value while processing the first tMOVrr. At this point, the spiller remembers fi#5 is available in %r0. Next it processes the second move. It restores the source before the move and spills the result afterwards. The move becomes a noop and is deleted. However, a spill has been inserted and that should invalidate reuse of %r0 for fi#5 and add reuse of %r1 for fi#5. Therefore, %reg1117 (which is also assigned fi#5) should get %r1, not %r0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34039 91177308-0d34-0410-b5e6-96231b3b80d8
2007-02-08Moved the MachOWriter and ELFWriter out of the Target/* files. Placed theBill Wendling
definition of it into the CodeGen library. This is so that a backend doesn't necessarily add in these writers if it doesn't use them (like in the lli program). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34034 91177308-0d34-0410-b5e6-96231b3b80d8
2007-02-08Added new method to add a "simple" code emitter. That is, to only addBill Wendling
the code emitter and not set variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34033 91177308-0d34-0410-b5e6-96231b3b80d8
2007-02-08Split the addPassesToEmitFile method up into two. This is so that we canBill Wendling
do some common stuff, then on our own add an object file writer (by calling a concrete function), and then do some finishing stuff, if need be. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34032 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-07push bytecode decompressor out through APIs. Now the bytecode readerChris Lattner
api's look like this: ModuleProvider *getBytecodeModuleProvider( const std::string &Filename, ///< Name of file to be read BCDecompressor_t *BCDC = Compressor::decompressToNewBuffer, std::string* ErrMsg = 0, ///< Optional error message holder BytecodeHandler* H = 0 ///< Optional handler for reader events ); This is ugly, but allows a client to say: getBytecodeModuleProvider("foo", 0); If they do this, there is no dependency on the compression libraries, saving codesize. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34012 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-07Fix Transforms/DeadArgElim/2007-02-07-FuncRename.ll, fallout from PR411.Chris Lattner
This happened because deadargelim now causes VMCore to auto-rename every function that it hacks arguments out of. Because it hacks arguments out of functions in a non-deterministic order, this caused the resultant numbering to be nondet. The fix is to just be careful to not rename functions! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34005 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-07In thumb mode, R3 is reserved, but it can be live in to the function. IfEvan Cheng
that is the case, whenever we use it as a scratch register, save it to R12 first and then restore it after the use. This is a temporary and truly horrible workaround! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33999 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-06Two fixes:Chris Lattner
1. Memset takes an i32 for the value to set, not i8. This was causing GCC to ICE all over the place (PR1183). 2. memcpy/memmove were not properly zext/trunc'ing the size in some cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33970 91177308-0d34-0410-b5e6-96231b3b80d8
