Chris Lattner b24eb91e2c CBackend is no longer here 
llvm-svn: 11416
 2004-02-13 23:29:37 +00:00
Chris Lattner 1f9c6eb358 CBackend now lives here 
llvm-svn: 11415
 2004-02-13 23:29:20 +00:00
Chris Lattner c5a4641c21 Do not advertise our -c option anymore 
llvm-svn: 11413
 2004-02-13 23:24:46 +00:00
Chris Lattner 92849b7dc9 Mercilessly rip the cbackend out of llvm-dis. Leave a helpful error message 
for those who have not heard the news.

 2004-02-13 23:22:40 +00:00
Chris Lattner c7dd48567f The cbackend has never had anything to do with llvm assembly writing 
llvm-svn: 11411
 2004-02-13 23:19:51 +00:00
Chris Lattner 3fba9dc096 Add support for -march=c 
llvm-svn: 11410
 2004-02-13 23:19:09 +00:00
Chris Lattner 0591bb5bc8 Convert the C backend into a target, for use with LLC. This allows us to use 
the lowerallocations pass to eliminate malloc/free warnings and hackish code

llvm-svn: 11409
 2004-02-13 23:18:48 +00:00
Chris Lattner 9fae109121 Change how we create the cwriter, and add a buttload of libraries that it now 
needs.  This will be fixed shortly

llvm-svn: 11407
 2004-02-13 23:01:14 +00:00
Chris Lattner b09176a1e2 Change access to the cwriter 
llvm-svn: 11406
 2004-02-13 23:00:45 +00:00
Chris Lattner d2b6e183e9 Make the cwriter use the lowerinvoke pass so that it can either use "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
 2004-02-13 23:00:29 +00:00
Chris Lattner 067b6bb9b2 New testcase. The CFE should not generate illegal LLVM intrinsics, even if 
the input program is horribly broken (like 126.gcc).

llvm-svn: 11401
 2004-02-13 22:04:41 +00:00
John Criswell 3b4195f344 Added check for target machine endian-ness and put the result into 
Makefile.config (ENDIAN variable is set to big or little).

llvm-svn: 11398
 2004-02-13 21:57:29 +00:00
Chris Lattner d17e15eddd Add support for a bunch more functions 
llvm-svn: 11395
 2004-02-13 21:21:48 +00:00
Alkis Evlogimenos 8cdd0215bf Remove getAllocatedRegNum(). Use getReg() instead. 
llvm-svn: 11393
 2004-02-13 21:01:20 +00:00
Alkis Evlogimenos ef9d025ebe Mark MachineBasicBlock::operator[] deprecated. 
llvm-svn: 11392
 2004-02-13 20:05:56 +00:00
Alkis Evlogimenos 1aa50dfae5 Define DEPRECATED so that it can be used in function and variable 
declarations.

llvm-svn: 11391
 2004-02-13 20:05:44 +00:00
Chris Lattner e00227248e Add support for fopen/fclose. Specifically with fopen, we were marking all of the 
operands as incomplete, though fopen is known to only read them.  This just adds
fclose for symmetry, though it doesn't gain anything.  This makes the dsgraphs for
181.mcf much more precise.

llvm-svn: 11390
 2004-02-13 20:05:32 +00:00
Alkis Evlogimenos de6a381691 Use getNumVirtualRegs(). 
Whitespace cleanups.

Chris Lattner 963f273734 Bug fixed 
llvm-svn: 11385
 2004-02-13 17:03:01 +00:00
Chris Lattner 283ffdfac5 Fix compilation of 126.gcc: intrinsic functions cannot throw, so they are not 
allowed in invoke instructions.  Thus, if we are inlining a call to an intrinsic
function into an invoke site, we don't need to turn the call into an invoke!

llvm-svn: 11384
 2004-02-13 16:47:35 +00:00
Chris Lattner 7db49ce5b4 Intrinsic functions cannot throw 
llvm-svn: 11383
 2004-02-13 16:46:46 +00:00
John Criswell d6687b9b82 Updated to list all code/directories that have additional or alternate 
licensing information.

Also added note to indicate that warrany disclaimer and the no-endorsement
clause applies to everything.

llvm-svn: 11382

Chris Lattner 9761271f0f Restructure code to handle memcpy/memmove 
llvm-svn: 11374

 2004-02-13 16:04:51 +00:00
Brian Gaeke 242ebf2523 Fix off-by-one in Interpreter::getFirstVarArg(), which was punishing 
any attempts by LLI to use varargs (possibly left over from the introduction
of IntrinsicLowering??)

llvm-svn: 11370
 2004-02-13 06:18:39 +00:00
Chris Lattner 337df9b905 Fine grainify namespacification, prune #includes

 2004-02-13 04:39:55 +00:00
Brian Gaeke e8f7c2f863 Add head-of-file comments and Doxygen comments. Tighten up a lot of whitespace. 
Rename SetMachineOperandConst's formal parameters to match other methods here.
Mark some methods as being used only by the SPARC back-end.
Fix a missing-paren bug in OutputValue().

llvm-svn: 11363
 2004-02-13 04:39:32 +00:00
Chris Lattner bb68a2209b Add support for memcpy and memmove intrinsics. Why isn't the cwriter using 
the intrinsiclowering code?? :(

Alkis Evlogimenos de8ac749fe Add parent pointer to MachineInstr that points to owning
