This has now been implemented as well. With some local hacks and a few manual changes to the generated code, the system unit for Darwin/x86-64 can now be compiled and successfully assembled. Note that this is with all inline assembly code removed (and pure inline assembly functions just returning 0 or its equivalent, so a lot of code is wrongly optimised away by llvm based on that). Some results are interesting, like the lowercase(shortstring) function becoming a rather impressive vectorised jungle: http://pastebin.com/vpugp80e . The only other vectorised functions in the system unit are lowercase(shortstring), UCS4StringToUnicodeString/Widestring, ArrayStringToPPChar and the helpers to add/sub/mul/symdif large sets. On the other hand, it seems that loading an array as a plain value in llvm bitcode results in rather suboptimal code (this is with -O2): http://pastebin.com/krXhuEzF :) Jonas _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel
