This compiles:

into:
_baz:
        srwi r2, r3, 1
        extsh r3, r2

on PPC, instead of:
_baz:

        srwi r2, r2, 9
        extsh r3, r2

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.

Chris Lattner 9ad5915559 SIGN_EXTEND_INREG does not demand its top bits. Give SimplifyDemandedBits 
a chance to hack on it.  This compiles:

int baz(long long a) { return (short)(((int)(a >>24)) >> 9); }

into:

        slwi r2, r3, 8
        srwi r2, r2, 9
        extsh r3, r2

instead of:

_baz:
        srwi r2, r4, 24
        rlwimi r2, r3, 8, 0, 23
        srwi r2, r2, 9

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.

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.

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.
