the bcreader if one is supplied to the bytecode reader's interface
functions.

1b17438aa8 The code generator should work with unreachable blocks. If not, then this 
is a bug that should be fixed in the code generator, not papered over with
the simplifycfg pass.  Eliminating this makes bugpoint much more useful

23a53aa9c4 I believe that the code generator now properly handles dead basic blocks. If not, 
this is a bug, and should be fixed.

8b486a114e Fix a regression from r1.224. In particular, codegen a cast from double -> 
float as a truncation by going through memory.  This truncation was being
skipped, which caused 175.vpr to fail after aggressive register promotion.

9c661c8e26 Do not set the `link' bit when branching to the first BB of a function, as it 
will cause an infinite loop.  The link bit is only used for calling functions.

3b04a8ac45 Initial checkin of a simple mod/ref analysis for global variables. This is 
still overly conservative and uses very simple data structures, but it is a
start, and allows elimination of a lot of loads.

ce8158d1d6 Now that the SparcV9 specific MachineCodeForInstruction class uses it's own 
map on the side, Instruction no longer has to be Annotable.  This reduces
the size of the Instruction class by another 4 bytes (on a 32-bit system).

4e7244e68e Do not find these ugly sparc-specific objects by using the annotation API on 
instructions.  Instead, keep a map of instructions -> MCFI objects in the
already sparc-specific class MachineFunctionInfo.  This will slow down the
sparc backend a bit, but it does not penalize the rest of LLVM!
