Reid Spencer 20754ac069 * Merge get_GVInitializer and getCharArrayLength into a single function ... named getConstantStringLength. This is the common part of StrCpy and StrLen optimizations and probably several others, yet to be written. It performs all the validity checks for looking at constant arrays that are supposed to be null-terminated strings and then computes the actual length of the string. * Implement the MemCpyOptimization class. This just turns memcpy of 1, 2, 4 and 8 byte data blocks that are properly aligned on those boundaries into a load and a store. Much more could be done here but alignment restrictions and lack of knowledge of the target instruction set prevent use from doing significantly more. That will have to be delegated to the code generators as they lower llvm.memcpy calls. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21562 91177308-0d34-0410-b5e6-96231b3b80d8		2005-04-26 07:45:18 +00:00
