Chris Lattner ac6db755c3 Adjust to the changed StructType interface. In particular, getElementTypes() is gone.

Brian Gaeke e869e0cfa8 Turn off "attribute weak" to pacify Mac OS X's system compiler, which prints a 
warning whenever it sees it.

John Criswell 65b3acdd5b Upon Chris's suggestion, moved the #ifdef's to the generated C code. 
This makes LLVM and the generated C code more portable.

John Criswell 83fb097ed0 Fixed the CBE on Solaris/Sparc. We need to define the return value of 
the write() system call because it returns 64 bits on Solaris 64 bit,
and an implicit return value of int says it returns 32 bits.
Admittedly, this is a bit of a hack.

Chris Lattner 9005b8000c ISO 9899 7.13.2.1 (3) says that "[...] the values of objects of automatic 
storage duration that are local to the function containing the invocation of the
[...] setjmp macro that do not have volatile-qualified type and have been
changed between the setjmp invocation and longjmp call are indeterminate."

As such, we have to mark all variables in a function that uses 'invoke' as
volatile.

This fixes PR77

llvm-svn: 9678
 2003-11-03 17:32:38 +00:00
Chris Lattner 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.

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

 2003-10-13 17:13:53 +00:00
Chris Lattner 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!!!!

Chris Lattner 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.

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

John Criswell 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.

Brian Gaeke 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.)
