* CBackend now lives hereChris Lattner2004-02-133-1437/+0

* Convert the C backend into a target, for use with LLC. This allows us to useChris Lattner2004-02-132-30/+51

* Make the cwriter use the lowerinvoke pass so that it can either use ↵Chris Lattner2004-02-131-123/+48
| | | | | | | | | | | "disabled exceptions" or "expensive exceptions" controlled by an option. Also refactor and eliminate a bunch of cruft. This is a temporary solution and causes millions of warnings to pour out of programs that use exceptions, but it should fix the problem with sparc and the 'write' declaration (PR190). Subsequent changes will make this stink much less llvm-svn: 11405

* Upon Chris's suggestion, moved the #ifdef's to the generated C code.John Criswell2003-12-101-8/+5
| | | | | | This makes LLVM and the generated C code more portable. llvm-svn: 10377
* Fixed the CBE on Solaris/Sparc. We need to define the return value ofJohn Criswell2003-12-101-1/+8
| | | | | | | | 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. llvm-svn: 10375

| | | | | | | | | | | | | 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: 10035
* Put all LLVM code into the llvm namespace, as per bug 109.Brian Gaeke2003-11-111-12/+16

* Work around a bug in GCC where it can't handle common variables marked weak.Chris Lattner2003-11-031-1/+8

* Fix bugs with attribute weak emissionChris Lattner2003-11-031-3/+6
| | | | llvm-svn: 9678
* This simplifies the CWriter code, makes the generated code easier to read,Chris Lattner2003-11-031-11/+2
| | | | | | and makes the output work with the intel compiler. Overall, a win. llvm-svn: 9671

* * Spell "necessary" correctlyChris Lattner2003-10-121-3/+24
| | | | | | | | | | | * 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!!!! llvm-svn: 9052
* * Be TBAA safeChris Lattner2003-10-121-32/+59
| | | | | | | | | | * 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. llvm-svn: 9048
* A couple of minor code cleanups.Chris Lattner2003-10-051-21/+16
| | | | | | Print literal doubles using ftostr instead of <<, because it yields higher precision numbers. llvm-svn: 8855
