* Fix for PR1406:Evan Cheng2007-05-141-2/+35
| | | | | | | | | | | | | v1 = r2 = move v1 = op r2<kill> ... r2 = move v1 = op r2<kill> Clear the first r2 kill if v1 and r2 are joined. llvm-svn: 37050

* Optimize PIC implementation. GOTOFF can be used when the symbol is definedLauro Ramos Venancio2007-05-141-1/+1

* Give names to the final result values of the part_set computations. ThisReid Spencer2007-05-141-2/+2

* Correct a few comments.Dan Gohman2007-05-141-5/+5
| | | | llvm-svn: 37034
* Add passes -view-cfg and -view-cfg-only that are like -print-cfg andDan Gohman2007-05-141-0/+42
| | | | | | | -print-cfg-only except they use the ViewCFG function, which displays the CFG rendered with graphviz with gv. llvm-svn: 37033
* Make the results for the rotate functions correct when rotateAmt == 0.Reid Spencer2007-05-141-0/+4
| | | | llvm-svn: 37026
* Add some things needed by the llvm-gcc version supporting bit accurate integerReid Spencer2007-05-131-1/+67
| | | | | | | | | | | types: 1. Functions to compute div/rem at the same time. 2. Further assurance that an APInt with 0 bitwidth cannot be constructed. 3. Left and right rotate operations. 4. An exactLogBase2 function which requires an exact power of two or it returns -1. llvm-svn: 37025

* Emit multiple common EH frames for multiple (including blank) personalityAnton Korobeynikov2007-05-132-34/+51
| | | | | | | | functions. This partly fixes PR1414: now we're restricted only to one personality function per eh frame, not per module. Further work on "multiple personalities" topic needs representative example. llvm-svn: 37018
* More DWARF-related things cleanup:Anton Korobeynikov2007-05-124-60/+85
| | | | | | | | | | 1. Fix PR1380 2. Apply Duncan's patch from PR1410 3. Insert workaround for "one personality function per module" as noted in PR1414 4. Emit correct debug frames for x86/linux. This partly fixes DebugInfo/2006-11-06-StackTrace.cpp: stack trace is shown correctly, but arguments for function on top of stack are displayed incorrectly. llvm-svn: 37015
* Fix shl to produce the correct result when the bitwidth is > 64 and theReid Spencer2007-05-121-0/+6
| | | | | | | shift amount is 0. Previously this code would do a lshr by the bit width which can lead to incorrect results. llvm-svn: 37010

* This patch extends the LoopUnroll pass to be able to unroll loopsDan Gohman2007-05-111-58/+193
| | | | | | | | | | | | | | | | | with unknown trip counts. This is left off by default, and a command-line option enables it. It also begins to separate loop unrolling into a utility routine; eventually it might be made usable from other passes. It currently works by inserting conditional branches between each unrolled iteration, unless it proves that the trip count is a multiple of a constant integer > 1, which it currently only does in the rare case that the trip count expression is a Mul operator with a ConstantInt operand. Eventually this information might be provided by other sources, for example by a pass that peels/splits the loop for this purpose. llvm-svn: 36990
