7be3ab2fb7 This simplifies the CWriter code, makes the generated code easier to read, 
and makes the output work with the intel compiler.  Overall, a win.

4fa54568a3 The "correct" fix for CBackend/2003-10-23-UnusedType.ll is to not even try 
to emit types which are not used.

1d243169d9 * Spell "necessary" correctly 
* Print floating point values using C99 hexadecimal style FP if possible.
  This increases the number of floating point constants that may be emitted
  inline, and improves precision for global variable initializers which
  can not be emitted in integer form.

This fixes the Olden/Power benchmark with the CBE!!!!

5d841b2de5 * Be TBAA safe 
* Fix isFPCSafeToPrint to find more constants safe to print, which it was
  failing because ftostr was padding with leading space characters.
* Scan the entire module for global constants instead of each function at a
  time.  This has the advantage of allowing us to emit constants at global
  scope instead of function scope.  This speeds FP programs quite a bit.

6e7ae58260 A couple of minor code cleanups. 
Print literal doubles using ftostr instead of <<, because it yields higher precision numbers.

6e264f078a Modified the code so that it generates (0) for setjmp() and abort() for 
longjmp() (and does not include setjmp.h).
This is to fix some problems on Sparc while non-local jumps are still
unimplemented.

46f8b71376 Use unified CWriter-X86/Printer name mangler. Do not bother using 
SlotCalculator in CWriter.  (Unfortunately, all this means a lot of
X86/Printer's methods have to be de-constified again.  Oh well.)

fbb9ab4913 - Fixed name mangling conditions to handle 'linkonce' linkage type. In 
particular, name mangling for GlobalValues only occurs when the linkage type is
internal or when the name must be mangled to avoid a collision.  See comments in
CWriter::getValueName for more information.

- 'inline' keyword is now emitted for functions with 'linkonce' linkage type.

- Fixed typos.

7610971759 It seems likely that floats would need a cast too, because they are 
ordinarily promoted to doubles.

04bdfe624c Fix 2003-06-23-PromotedExprs.llx -- if we are adding two bytes we better 
explicitly cast the result to be a byte, or C will gleefully promote it
to int.

87b4f0765c lib/CWriter/Writer.cpp: Copy AsmWriter's ConstantFP checking code here 
into a new function FPCSafeToPrint(), and use it in printConstant()
and printFunction() to decide whether we should output ConstantFPs as
floating-point constants or as references to stack-allocated variables.

lib/VMCore/AsmWriter.cpp: Fix an apparent typo in the code mentioned above.

fb70cf528e Fairly major change: emit fixed sized allocas in the entry block as a variable, 
instead of a variable pointer and an alloca.  All accesses to the variable then
use the address-of operator to access it.  This plays better with the internal
GCC code generation phases, which bail early on functions which contain allocas.
It also makes the code a bit easier to read.
