2011-02-21Revert r124611 - "Keep track of incoming argument's location while emitting ↵Devang Patel
LiveIns." In other words, do not keep track of argument's location. The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body. This requires some coordination with debugger to get this working. - The debugger needs to be aware of prolog_end attribute attached with line table entries. - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126155 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-21Add SplitKit::isOriginalEndpoint and use it to force live range splitting to ↵Jakob Stoklund Olesen
terminate. An original endpoint is an instruction that killed or defined the original live range before any live ranges were split. When splitting global live ranges, avoid creating local live ranges without any original endpoints. We may still create global live ranges without original endpoints, but such a range won't be split again, and live range splitting still terminates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126151 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-21If the phi node was used by an unreachable instruction that ends up usingDuncan Sands
itself without going via a phi node then we could return false here in spite of making a change. Also, tweak the comment because this method can (and always could) return true without deleting the original phi node. For example, if the phi node was used by a read-only invoke instruction which is used by another phi node phi2 which is only used by and only uses the invoke, then phi2 would be deleted but not the invoke instruction and not the original phi node. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126129 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-21The signed version of our "magic number" computation for the integer ↵Cameron Zwarich
approximation of a constant had a minor typo introduced when copying it from the book, which caused it to favor negative approximations over positive approximations in many cases.

2011-02-19rewrite the memset_pattern pattern generation stuff to accept any 2/4/8/16-byteChris Lattner
constant, including globals. This makes us generate much more "pretty" pattern globals as well because it doesn't break it down to an array of bytes all the time. This enables us to handle stores of relocatable globals. This kicks in about 48 times in 254.gap, giving us stuff like this: @.memset_pattern40 = internal constant [2 x %struct.TypHeader* (%struct.TypHeader*, %struct.TypHeader*)*] [%struct.TypHeader* (%struct.TypHeader*, %struct .TypHeader*)* @IsFalse, %struct.TypHeader* (%struct.TypHeader*, %struct.TypHeader*)* @IsFalse], align 16 ... call void @memset_pattern16(i8* %scevgep5859, i8* bitcast ([2 x %struct.TypHeader* (%struct.TypHeader*, %struct.TypHeader*)*]* @.memset_pattern40 to i8* ), i64 %tmp75) nounwind git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126044 91177308-0d34-0410-b5e6-96231b3b80d8
