9860e77110 * 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.

dd76acac3f A couple of minor code cleanups. 
Print literal doubles using ftostr instead of <<, because it yields higher precision numbers.

506dad0664 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.

X86/Printer's methods have to be de-constified again.  Oh well.)

54f6032dae - 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.

e99f4cf4ac It seems likely that floats would need a cast too, because they are 
ordinarily promoted to doubles.

b471a23a85 lib/CWriter/Writer.cpp: Copy AsmWriter's ConstantFP checking code here 
into a new function FPCSafeToPrint(), and use it in printConstant()

floating-point constants or as references to stack-allocated variables.

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

a8ab89e3da 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.
