45a7ca9b23 * Only turn a load to UNDEF if all of its outputs have no uses (indexed loads 
produce two results.)
* Do not touch volatile loads.

e7cf56aeee Continue refactoring inline asm code. If there is an earlyclobber output 
register, preallocate all input registers and the early clobbered output.

c9a83e4f19 If an archive is not recognized as an LLVM bytecode archive then declare 
that it is native so that the linker will pass it on downstream. This avoids
a problem where the native link line fails because there is both a .so and
a .a file. The .a file gets processed as bytecode and then dropped from the
command line.

b30c925046 Implement much expanded dumper support. We now print stuff like: 
<MODULE_BLOCK NumWords=27 BlockCodeSize=3>
  <TYPE_BLOCK NumWords=7 BlockCodeSize=4>
    <NUMENTRY op0=7>
    <POINTER op0=1>
    <FUNCTION op0=0 op1=2 op2=2 op3=2 op4=2>
    <VECTOR op0=2 op1=3>
    <INTEGER op0=64>
    <VECTOR op0=8 op1=5>
    <INTEGER op0=16>
    <VOID>
...

With work, the operands can be pretty printed symbolically.

c453f76e2b Switch the bitcode reader interface to take a MemoryBuffer instead of knowing 
anything about disk I/O itself.  This greatly simplifies its interface -
eliminating the need for the ReaderWrappers.cpp file.

This adds a new option to llvm-dis (-bitcode) which instructs it to read
the input file as bitcode.  Until/unless the bytecode reader is taught to
read from MemoryBuffer, there is no way to handle stdin reading without it.

I don't plan to switch the bytecode reader over, I'd rather delete it :),
so the option will stay around temporarily.
