* 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
* 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

* Make the apint construction more effective.Zhou Sheng2007-04-131-3/+3
| | | | llvm-svn: 35960
* improve the patch for PR1318 to also support grouped options with customChris Lattner2007-04-121-7/+12
| | | | | | | | | handlers (like the pass list). My previous fix only supported *new* command line options, not additions to old ones. This fixes test/Feature/load_module.ll llvm-svn: 35935
* Fix PR1318 by reacting appropriately to a mutating option list.Chris Lattner2007-04-111-0/+14
| | | | llvm-svn: 35905
* Fix an approximate calculation in an assertion not to give false negatives.Reid Spencer2007-04-111-1/+1
| | | | llvm-svn: 35901
* For PR1291:Reid Spencer2007-04-071-2/+2
| | | | | | | Change uses of sys::Path class to sys::PathWithStatus in those places where the file status information is needed. llvm-svn: 35743
* Add signExtend to ConstantRange, to complement zeroExtend and truncate.Nick Lewycky2007-04-071-0/+17
| | | | llvm-svn: 35733
* Fix a bug in my earlier commit which exposed positional options backwards.Chris Lattner2007-04-071-3/+9
| | | | | | This fixes llvm-ar. llvm-svn: 35727
* rearchitect the registration mechanism used by the command line option stuff.Chris Lattner2007-04-061-65/+84
| | | | | | | | | | This dramatically reduce the amount of memory allocated by the commandline stuff at static init time, changing it to build local data structures when ParseCommandLineOptions is called. In a dummy empty program that links some llvm libraries, this reduces the number of malloc'd bytes from 4864 to 3360 on entry to main. Most of that memory is now allocated by non-commandline related stuff. llvm-svn: 35701
* remove the dead removeArgument method, rename Options to OptionsMap.Chris Lattner2007-04-051-61/+30

| | | | llvm-svn: 35666
* use calloc instead of new/memset, it is more efficientChris Lattner2007-04-041-4/+2
| | | | llvm-svn: 35644
* Extend StringMap to support being initialized as completely empty. WhenChris Lattner2007-04-041-2/+22
| | | | | | initialized this way, they do not do a malloc to allocate their buckets. llvm-svn: 35642

| | | | llvm-svn: 35632

| | | | llvm-svn: 35534
* For PR789:Reid Spencer2007-03-291-5/+6
| | | | | | | | Make the sys::Path::getFileStatus function more efficient by having it return a pointer to the FileStatus structure rather than copy it. Adjust uses of the function accordingly. Also, fix some memory issues in sys::Path. llvm-svn: 35476
* For PR789:Reid Spencer2007-03-291-2/+2
| | | | | | Updates for change in interface of getFileStatus method of sys::Path class. llvm-svn: 35458
* Fix a bug in getAllOnesValue() which brokeZhou Sheng2007-03-211-1/+1

* Fix ashr for bitwidths > 64. This is now validated up to 1024 bits.Reid Spencer2007-03-021-33/+49
| | | | llvm-svn: 34852
* Use a better algorithm for rounding sqrt results. Change the FIXME aboutReid Spencer2007-03-021-8/+12
| | | | | | | | | this to a NOTE: because pari/gp results start to get rounded incorrectly after 192 bits of precision. APInt and pari/gp never differ by more than 1, but APInt is more accurate because it does not lose precision after 192 bits as does pari/gp. llvm-svn: 34834

* Fix a problem where shifting by 64-bits leads to incorrect results on PPCReid Spencer2007-03-021-1/+4
