Chris Lattner 7598c316e5 Take another .7 seconds off of linear scan time.

Chris Lattner 850852c789 Add a counter for the number of times linscan has to backtrack. Start using 
the iterator hints we have to speed up overlaps().  This speeds linscan up
by about .2s (out of 8.7) on 175.vpr for PPC.

Chris Lattner cb0c9655bf Add ability to give hints to the overlaps routines.

Chris Lattner a1f7779876 * Improve comments/documentation substantially 
* Eliminate the releaseMemory method, this is not an analysis
* Change the fixed, active, and inactive lists of intervals to maintain an
  iterator for the current position in the interval.  This allows us to do
  constant time increments of the iterator instead of having to do a binary
  search to find our liverange in our liveinterval all of the time, which
  substantially speeds up cases where LiveIntervals have many LiveRanges
  - which is very common for physical registers.  On targets with many
  physregs, this can make a noticable difference.

  With a release build of LLC for PPC, this halves the time in
  processInactiveIntervals and processActiveIntervals, from 1.5s to .75s.

  This also lays the ground for more to come.

the void value.

Reid Spencer 91234ff57a Fix PR458: 
* Don't include Makefile.rules in set of preconditions, it never has to be
  copied to objdir.
* Enable the "update makefile first before executing targets" feature in
  gnu make by *not* using a full path to the Makefile in the rule.

Reid Spencer 67c46c8d70 Fix some things for Mac OSX archives: 
* ensure trailing spaces are eliminated so they don't factor into the
  length of a member's name.
* make sure all the bytes of a name are written even if the name ends in
  multiple null characters (bug in OSX ar)
* make sure we provide the full member name when searching for symbols so
  the module name is not accidentally duplicated.

Reid Spencer b58bf5fa28 Make sure we parse bytecode with a module identifier that reflects the full

llvm-svn: 17910
 2004-11-17 16:14:21 +00:00
Reid Spencer 0dea46fe67 Despite documentation to the contrary, Mac OSX and BSD 4.4 archive formats 
*do* include the length of the long file in the length of the member and
they are *not* null terminated.

Tanya Lattner 7beb51cd29 Added my own defMap. Only saving values that are not loop invariant. Fixed a couple of assertions that were triggered due to registers not being allocated. These both had to do with PHINodes.

being linked do not need to be remapped any longer.

Brian Gaeke 97f8adffff Correct the implicit-defs information for indirect and direct calls. 
You can't have implicit defs that overlap explicit defs, or implicit
defs that alias one another.

Chris Lattner 2f0557d0e4 Take advantage of the fact that we are allowed to clobber the input module 
by splicing function bodies from the src module to the destination module.

This speeds up linking quite a bit, e.g. gccld time on 176.gcc from 26s -> 20s
when forming the .rbc file, with a profile build.  One of the really strange
but cool effects of this patch is that it speeds up the optimizers as well,
from 12s -> 10.7s, presumably because of better locality???

In any case, this is just a first step.  We can trivially get rid of the
LocalMap now and do other simplifications.
