  1. 273f7e4 Detect and handle COPY in many places. by Jakob Stoklund Olesen · 15 years ago
  2. 2b4e727 Re-apply 105308 with fix. by Evan Cheng · 15 years ago
  3. 3844173 Revert 105308. by Bob Wilson · 15 years ago
  4. 9d709a8 Enable machine cse of instructions which define physical registers. by Evan Cheng · 15 years ago
  5. e81d010 Make this LookAheadLimit, not the uninitialized LookAheadLeft. by Eric Christopher · 15 years ago
  6. 835810b Allow machine cse to cse instructions which define physical registers. Controlled by option -machine-cse-phys-defs. by Evan Cheng · 15 years ago
  7. 49b4589 Add a utility function for conservatively clearing kill flags, and make by Dan Gohman · 15 years ago
  8. 3115698 Rewrite machine cse to avoid recursion. by Evan Cheng · 15 years ago
  9. d6060a4 Typo. by Evan Cheng · 15 years ago
  10. db8771a After trivial coalescing, the MI being visited may have become a copy. Avoid adding it to CSE hash table since copies aren't being considered for CSE and they may be deleted. by Evan Cheng · 15 years ago
  11. 2250425 dbg_value may end a block. by Evan Cheng · 15 years ago
  12. 112e5e7 Code clean up. by Evan Cheng · 15 years ago
  13. e68ea06 Fix debug_value handling. by Dale Johannesen · 15 years ago
  14. 2938a00 Add a couple more heuristics to neuter machine cse some more. by Evan Cheng · 15 years ago
  15. bfc9999 Allow more cross-rc coalescing. by Evan Cheng · 15 years ago
  16. 1552ccc Don't do illegal cross-class coalescing. by Jakob Stoklund Olesen · 15 years ago
  17. 31f94c7 - Make the machine cse dumb coalescer (as opposed to the more awesome simple by Evan Cheng · 15 years ago
  18. 5196018 Don't waste time trying to CSE labels, phis, inline asm. Definitely avoid cse implicit-def for obvious performance reason. by Evan Cheng · 15 years ago
  19. 6c3b8ac Restrict machine cse to really trivial coalescing. Leave the heavy lifting to a real coalescer. by Evan Cheng · 15 years ago
  20. 6cc1aea Don't update physical register def. by Evan Cheng · 15 years ago
  21. a5f32cb Avoid cse load instructions unless they are known to be invariant loads. by Evan Cheng · 15 years ago
  22. b3958e8 Look ahead a bit to determine if a physical register def that is not marked dead is really alive. This is necessary to catch a lot of common cse opportunities for targets like x86. by Evan Cheng · 15 years ago
  23. 67bda72 Fix a logic error. An instruction that has a live physical register def cannot be CSE'ed, but it *can* be used to replace a common subexpression. by Evan Cheng · 15 years ago
  24. 05bdcbb Re-apply r97667 but with a little bit of thought put into the patch. This implements a special DenseMapInfo trait for DenseMap<MachineInstr*> that compare the value of the MachineInstr rather than the pointer value. Since the hashing and equality test functions ignore defs it's useful for doing CSE kind optimization. by Evan Cheng · 15 years ago
  25. 319dfa3 Revert 97667. It broke a bunch of tests. by Dan Gohman · 15 years ago
  26. a054ae0 Move DenseMapInfo for MachineInstr* to MachineInstr.h by Evan Cheng · 15 years ago
  27. 16b48b8 Machine CSE work in progress. It's doing some CSE now. But implicit def of physical registers are getting in the way. by Evan Cheng · 15 years ago
  28. 6ba9554 Work in progress. Finding some cse now. by Evan Cheng · 15 years ago
  29. c5bbba1 Fix typo. by Evan Cheng · 15 years ago
  30. c6fe333 Add skeleton of a machine level cse pass. by Evan Cheng · 15 years ago
