program exits with code 0, no error. If the call does not work/succeed, main
returns 1, so we notice it. The other way around doesn't work. :)

(lib/Target/X86) InstSelectSimple.cpp:
Include llvm/DerivedTypes.h and iostream.
Refactor visitMul out into a wrapper around doMultiply(), so that we
can do multiplications on temporary values when we are doing
getelementptrs.
Refactor part of getReg out into makeAnotherReg, so that we can create
registers willy-nilly to hold temporary values, when we are doing
getelementptrs.
Add stub implementations of visitMallocInst and visitAllocaInst.
Add initial implementation of visitGetElementPtrInst.
In copyConstantToRegister:
We throw a *lot* of our asserts here. So, when we want to throw an
assert, print out to stderr whatever expr or whatever constant made
us barf.
Support copying ConstantPointerNull to register, using a move immediate
of zero.
Rename FLDr4 and FLDr8 to FLDr32 and FLDr64, so that they match the meanings
of the numbers in the other instruction names. All uses modified.
Teach visitCallInst to extract byte- and short-class return values
from subregs of EAX. Add a FIXME note about how we would do it for
float-class return values.
Add a FIXME note about how we would cast float to int and back.
X86InstrInfo.def:
Rename FLDr4 and FLDr8 to FLDr32 and FLDr64, so that they match the meanings
of the numbers in the other instruction names. All uses modified.
(tools/jello) GlobalVars.cpp:
Include iostream.
If we have to emit a floating-point constant to memory, gamble and use
the same method as for ints.
If we have to emit a ConstantPointerNull to memory, try using a "void *"
and "NULL".
Otherwise, if we are going to throw an assert, print out whatever constant
made us barf, first.

using the Cilk multi-threaded runtime system to execute parallel code.
The current version inserts too many sync() operations in the program
because it does not attempt to optimize their placement.

exposes some routines needed for code generation for that pass.

fact that the incoming nodes may be merged away at intermediate

to track the nodes being merged. All this now happens in a
