* Replace the "implementation" keyword with "checkpoint". This more accuratelyReid Spencer2007-03-282-3/+3
| | | | | | | | | describes its function as check against unresolved types and definitions. This is handy for forcing error messages in assembly test cases or otherwise ensuring that everything is resolved at that point in the assembly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35410 91177308-0d34-0410-b5e6-96231b3b80d8

* Clean up codes in ComputeMaskedBits():Zhou Sheng2007-03-281-29/+27
| | | | | | | | | 1. Line out nested use of zext/trunc. 2. Make more use of getHighBitsSet/getLowBitsSet. 3. Use APInt[] != 0 instead of "(APInt & SignBit) != 0". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35408 91177308-0d34-0410-b5e6-96231b3b80d8

* GEP index sinking fixes:Evan Cheng2007-03-281-40/+35
| | | | | | | | | | 1) Take address scale into consideration. e.g. i32* -> scale 4. 2) Examine all the users of GEP. 3) Generalize to inter-block GEP's (no longer uses loopinfo). 4) Don't do xform if GEP has other variable index(es). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35403 91177308-0d34-0410-b5e6-96231b3b80d8
