  • 4a7bc06553 Minor error. Vincentius Robby 2007-06-20 15:04:36 -04:00
  • d540dde5b4 Removed "adding instead of dividing" trick. Caused slowdown in performance instead of speeding up. Vincentius Robby 2007-06-20 14:54:17 -04:00
  • f65e2710ec Don't do checker stuff if the checker is not defined Nathan Binkert 2007-06-20 08:15:06 -07:00
  • b47737dde7 Make sure all parameters have default values if they're supposed to and make sure parameters have the right type. Also make sure that any object that should be an intermediate type has the right options set. Nathan Binkert 2007-06-20 08:14:11 -07:00
  • 438ec924d6 Don't go over 80 chars per line Nathan Binkert 2007-06-20 08:12:10 -07:00
  • a68ddf685c Make memory instructions work better, add more macroop implementations, add an lea microop, move EmulEnv into it's own .cc and .hh. Gabe Black 2007-06-20 15:02:50 +00:00
  • 5c48a05813 Merge zizzer.eecs.umich.edu:/bk/newmem into doughnut.hpl.hp.com:/home/gblack/newmem-o3-micro Gabe Black 2007-06-19 18:54:40 -07:00
  • d2ccf5e509 More faithfulness to what instructions should work in what modes, and added the MOVSXD instruction. Gabe Black 2007-06-19 22:40:10 +00:00
  • cc796de962 Missed an "offset" to get rid of. Gabe Black 2007-06-19 19:01:02 +00:00
  • ea70e6d6da Make branches work by repopulating the predecoder every time through. This is probably fine as far as the predecoder goes, but the simple cpu might want to not refetch something it already has. That reintroduces the self modifying code problem though. Gabe Black 2007-06-19 18:17:34 +00:00
  • d496492793 Make instructions that are illegal in 64 bit mode not do the wrong thing in 64 bit mode. Also add in more versions of PUSH and POP, and a version of near CALL. Gabe Black 2007-06-19 17:56:06 +00:00

  • 056cfc345b Get rid of the commented out versions of macroops which have been reimplemented. The comments are basically functioning like a todo list. Gabe Black 2007-06-19 14:26:42 +00:00
  • 053c715f21 Merge zizzer.eecs.umich.edu:/bk/newmem into ahchoo.blinky.homelinux.org:/home/gblack/m5/newmem-x86 Gabe Black 2007-06-19 14:18:46 +00:00
  • 6e286cddfa Get rid of the immediate and displacement components of the EmulEnv struct and use them directly out of the instruction. The extra copies are conceptually realistic but are just innefficient as implemented. Also don't use the zeroeth microcode register for general storage since it's now the zero register, and implement a load and a store microops. Gabe Black 2007-06-19 14:18:25 +00:00
  • 8caef7d25a Add a stack size bitfield and expose the mode component of the ExtMachInst. Gabe Black 2007-06-19 14:15:21 +00:00
  • 1012fd4427 Add a function to print out segment names. Gabe Black 2007-06-19 14:14:17 +00:00
  • 2d08ab0cc2 fix bug in timing cpu. getTime() is the time the requset was created, not the time it was repsonded to. In timing mode the time it was responded to is curTick. Doesn't change the results, but it does make implementation of nextCycle() more difficult Ali Saidi 2007-06-18 18:11:07 -04:00

  • 6c12577937 Add in incomplete pick and merge functions which read and write pieces of registers, and fill out microcode disassembly. Gabe Black 2007-06-18 14:15:00 +00:00
  • d69a763833 Merge vm1.(none):/home/stever/bk/newmem-head into vm1.(none):/home/stever/bk/newmem-cache2 Steve Reinhardt 2007-06-17 17:30:24 -07:00
  • 35cf19d441 More major reorg of cache. Seems to work for atomic mode now, timing mode still broken. Steve Reinhardt 2007-06-17 17:27:53 -07:00
  • c2a97387cf since the o3 cpu perlbmk regression doesn't work, just delete it. Perhaps the regression will terminate now Ali Saidi 2007-06-17 14:01:01 -04:00

  • 20ec77fdc1 Get rid of some debug output and let macroops set headers in their constructor. The intention is to allow them to modify the emulation environment struct before it's used to construct its microops. Gabe Black 2007-06-14 13:47:52 +00:00
