Duncan Sands 69300a2f47 When passing a parameter using the 'byval' mechanism, inline code needs to be used ... to perform the copy, which may be of lots of memory [*]. It would be good if the fall-back code generated something reasonable, i.e. did the copy in a loop, rather than vast numbers of loads and stores. Add a note about this. Currently target specific code seems to always kick in so this is more of a theoretical issue rather than a practical one now that X86 has been fixed. [*] It's amazing how often people pass mega-byte long arrays by copy... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118275 91177308-0d34-0410-b5e6-96231b3b80d8		2010-11-05 15:20:29 +00:00
