Chris Lattner af039c53c0 improve the patch for PR1318 to also support grouped options with custom
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

Chris Lattner 5247f60d20 rearchitect the registration mechanism used by the command line option stuff.
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
2007-04-06 21:06:55 +00:00
Chris Lattner 2031b02faf remove the dead removeArgument method, rename Options to OptionsMap.

Reid Spencer 200c6f9c3d For PR789:
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
2007-03-29 19:05:44 +00:00

2007-03-02 22:39:11 +00:00
Reid Spencer cf8175617d Use a better algorithm for rounding sqrt results. Change the FIXME about
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.

Reid Spencer 31acef50ad Implement countLeadingOnes() and getMinSignedBits(). This helps to minimize
the bit width of negative numbers by computing the minimum bit width for a
negative value. E.g. 0x1800000000000000 could be just 0x8000000000000000

llvm-svn: 34695
2007-02-27 21:59:26 +00:00
Reid Spencer 70cb5d4287 Improve APInt interface:
1. Add unsigned and signed versions of methods so a "bool" argument doesn't
   need to be passed in.
2. Make the various getMin/getMax functions all be inline since they are
   so simple.
3. Simplify sdiv and srem code.
