Evan Cheng 7818c03c6b Fix for PR1306. 
- A register def / use now implicitly affects sub-register liveness but does
not affect liveness information of super-registers.
- Def of a larger register (if followed by a use later) is treated as
read/mod/write of a smaller register.

llvm-svn: 36234
 2007-04-18 00:43:05 +00:00
Evan Cheng b881bdabd9 Copy coalescing change to prevent a physical register from being pin to a 
long live interval that has low usage density.
1. Change order of coalescing to join physical registers with virtual
   registers first before virtual register intervals become too long.
2. Check size and usage density to determine if it's worthwhile to join.
3. If joining is aborted, assign virtual register live interval allocation
   preference field to the physical register.
4. Register allocator should try to allocate to the preferred register
   first (if available) to create identify moves that can be eliminated.

llvm-svn: 36218
 2007-04-17 20:32:26 +00:00
Evan Cheng 57b5214d59 Add a register allocation preference field; add a method to compute size of a live interval.

Chris Lattner 51109b7830 Commit an patch from Gabor Greif in Mar 2005. This eliminates the tail 
pointer from ilist, storing it in the prev pointer of the first node in the
list instead.

This shrinks ilist from 8 to 4 bytes, BasicBlock from 40->36 bytes, Function
from 76->68 bytes, Module from 52->44 bytes.

 2007-04-17 05:33:04 +00:00
Chris Lattner 3c2ff10b93 merge several fields in GlobalValue to use the same word, move CallingConv 
field into SubclassData in Value.  This shrinks GlobalVAlue from 48->40
bytes, Function from 88->76, and GlobalVariable from 76->68.  This trims
4640 bytes off my testcase, reading a bc file without materializing any
functions.

llvm-svn: 36192
 2007-04-17 04:31:29 +00:00
Chris Lattner 422cfcdcb3 The (negative) offset from a SymbolTableListTraits-using ilist to its container 
object is always constant.  As such, evaluate it at compile time instead of storing
it as an ivar in SymbolTableListTraits.  This shrinks every SymbolTableListTraits
ilist by a word, shrinking BasicBlock from 44->40 bytes, Function from 96->88 bytes,
and Module from 60->52 bytes.

llvm-svn: 36189
 2007-04-17 04:04:14 +00:00
Chris Lattner b47aa543bb Refactor SymbolTableListTraits to only have a single pointer in it, instead 
of two.  This shrinkifies Function by 8 bytes (104->96) and Module by 8
bytes (68->60).  On a testcase of mine, this reduces the memory used to
read a module header from 565680b to 561024, a little over 4K.

Reid Spencer 9c2eec377e For PR1328:

Reid Spencer d4e07f200a Actually, for getHighBitsSet and getLowBitsSet, don't make a 0 bit size 
illegal. Instead do the 0 valued construction for the user. This is because
the caller may not know (or care to check) that the number of bits set is
zero.

llvm-svn: 35315
 2007-03-25 00:01:47 +00:00
Reid Spencer 42fbb4fbe3 Make it illegal to set 0 bits in getHighBitsSet and getLowBitsSet. For that 
they should have used the uint64_t constructor. This avoids causing
undefined results via shifts by the word size when the bit width is an
exact multiple of the word size.

llvm-svn: 35313
 2007-03-24 23:47:58 +00:00
Reid Spencer 790631ff2d In the getBitsSet function, don't optimize for a common case that is 
already covered by getLowBitsSet (i.e. when loBits==0). Consequently, remove
the default value for loBits and reorder the arguments to the more natural
loBits, hiBits order. This makes it more clear that this function is for bit
groups in the middle of the bit width and not towards one end or the other.
