2007-02-25Rework GlobalValue::removeDeadConstantUsers to always remove dead constantChris Lattner
exprs hanging off a global, even if the global is not otherwise dead. This requires some tricky iterator gymnastics. This implements Transforms/GlobalOpt/constantexpr-dangle.ll by deleting a constantexpr that made it appear that the address of the function was taken. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34608 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-251. Provide more detail in file comment.Reid Spencer
2. Move comments for methods to .h file, delete them in .cpp file. 3. All places that were doing manual clear of high order bits now call the clearUnusedBits() method in order to not depend on undefined behavior of the >> operator when the number of bits shifted equals the word size. 4. Reduced # of loc by using the new result of clearUnusedBits() method. 5. Simplified logic (decreased indentation) in a few places. 6. Added code comments to larger functions that needed them. 7. Added FIXME notes about weak implementations of things (e.g. bit-by-bit shift right is sub-optimal). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34603 91177308-0d34-0410-b5e6-96231b3b80d8
2007-02-25Fix clearUnusedBits to not depend on "undefined behavior" of >> operatorReid Spencer
when the bit size is equal to the word size. This happens to work out okay on x86, but might not on other platforms. The change just detects when there are no bits to clear (because BitWidth is a multiple of the word size) and returns early. Also, move some comments from .cpp file into header. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34602 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-25move LowerRET into the 'Return Value Calling Convention Implementation'Chris Lattner
section of the file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34589 91177308-0d34-0410-b5e6-96231b3b80d8
2007-02-25make all Lower*CallTo implementations use LowerCallResult to handle theirChris Lattner
result value stuff. This eliminates a bunch of duplicated code and now GetRetValueLocs is the sole place that decides where a value is returned. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34588 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-25factor a bunch of code out of LowerCCCCallTo into a new LowerCallResultChris Lattner
function. This function now uses GetRetValueLocs to determine *where* the result values are located and concerns itself with *how* to pull the values out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34586 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-25fold trivial token factor nodes. This allows us to compileChris Lattner
test/CodeGen/X86/fp-stack-ret.ll into: movl 4(%esp), %eax fldl (%eax) ret instead of: subl $12, %esp movl 16(%esp), %eax movsd (%eax), %xmm0 movsd %xmm0, (%esp) fldl (%esp) addl $12, %esp ret by eliminating a token factor that blocked a check. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34584 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-25simplify result value lowering by splitting the selection of *where* to returnChris Lattner
registers out from the logic of *how* to return them. This changes X86-64 to mark EAX live out when returning a 32-bit value, where before it marked RAX liveout. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34582 91177308-0d34-0410-b5e6-96231b3b80d8
