* For PR950:Reid Spencer2006-10-201-11/+11
| | | | | | | | This patch implements the first increment for the Signless Types feature. All changes pertain to removing the ConstantSInt and ConstantUInt classes in favor of just using ConstantInt. llvm-svn: 31063
* Simplify some code, reformat break'sChris Lattner2006-09-281-6/+12
| | | | llvm-svn: 30660
* Added some eye-candy for Subtarget type checkingAnton Korobeynikov2006-09-171-1/+9
| | | | | | Added X86 StdCall & FastCall calling conventions. Codegen will follow. llvm-svn: 30446
* Adding dllimport, dllexport and external weak linkage types.Anton Korobeynikov2006-09-141-1/+12
| | | | | | | | | DLL* linkages got full (I hope) codegeneration support in C & both x86 assembler backends. External weak linkage added for future use, we don't provide any codegeneration, etc. support for it. llvm-svn: 30374
* Add cbe support for powiChris Lattner2006-09-091-0/+10
| | | | llvm-svn: 30226
* Completely rearchitect the interface between targets and the pass manager.Chris Lattner2006-09-041-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | This pass: 1. Splits TargetMachine into TargetMachine (generic targets, can be implemented any way, like the CBE) and LLVMTargetMachine (subclass of TM that is used by things using libcodegen and other support). 2. Instead of having each target fully populate the passmgr for file or JIT output, move all this to common code, and give targets hooks they can implement. 3. Commonalize the target population stuff between file emission and JIT emission. 4. All (native code) codegen stuff now happens in a FunctionPassManager, which paves the way for "fast -O0" stuff in the CFE later, and now LLC could lazily stream .bc files from disk to use less memory. 5. There are now many fewer #includes and the targets don't depend on the scalar xforms or libanalysis anymore (but codegen does). 6. Changing common code generator pass ordering stuff no longer requires touching all targets. 7. The JIT now has the option of "-fast" codegen or normal optimized codegen, which is now orthogonal to the fact that JIT'ing is being done. llvm-svn: 30081
* Make functions with an "asm" name propagate that asm name into the cbe.c file.Chris Lattner2006-07-281-0/+6
| | | | | | This fixes link errors on programs with these on targets with prefixes. llvm-svn: 29390
* __i386__, __i386, etc. are not defined for x86-64. Use __x86_64__.Evan Cheng2006-06-201-1/+2
| | | | llvm-svn: 28881
* Now that PR633 is implemented, the CBE can know to emit _setjmp/_longjmpChris Lattner2006-06-061-0/+6
| | | | | | | when available. This speeds up hexxagon from 18.61s to 16.61s with the CBE on PPC Mac OS (for reference, LLC is 15.48s and GCC is 23.35s). llvm-svn: 28697
* Add mingw support, patch contributed by AntonChris Lattner2006-06-021-1/+1
| | | | llvm-svn: 28661
* Fix casting so there's no warning on Alpha.Reid Spencer2006-05-311-1/+1
| | | | llvm-svn: 28605
* For PR786:Reid Spencer2006-05-241-1/+1
| | | | | | | | Minor tweaks in public headers and a few .cpp files so that LLVM can build successfully with -pedantic and projects using LLVM with -pedantic don't get warnings from LLVM. There's still more -pedantic warnings to fix. llvm-svn: 28453
* Print struct return functions and calls as actually returning the hiddenChris Lattner2006-05-231-75/+171
| | | | | | | | argument struct pointer, enabling ABI compatibility for the CBE with platforms with strange struct-return ABIs. This fixes 252.eon and CoyoteBench/fftbench on Darwin/X86 among other things. llvm-svn: 28442
* Add checks for __OpenBSD__.Jeff Cohen2006-04-171-1/+1
| | | | llvm-svn: 27761
* Modify how CBE handles #lines.Jim Laskey2006-03-231-9/+5
| | | | llvm-svn: 26990
* Eliminate IntrinsicLowering from TargetMachine.Chris Lattner2006-03-231-3/+3
| | | | | | Make the CBE and V9 backends create their own, since they're the only ones that use it. llvm-svn: 26974
* Handle builtins that directly correspond to GCC builtins.Chris Lattner2006-03-131-2/+25
| | | | llvm-svn: 26737
* Handle the removal of the debug chain.Jim Laskey2006-03-131-2/+2
| | | | llvm-svn: 26729
* Add #line support for CBE.Jim Laskey2006-03-081-0/+17
| | | | llvm-svn: 26621
* Two things:Chris Lattner2006-03-071-12/+89
| | | | | | | | 1. Don't emit debug info, or other llvm.metadata to the .cbe.c file. 2. Mark static ctors/dtors as such, so that bugpoint works on C++ code compiled with the new CFE. llvm-svn: 26602
* Another hack due to allowing multiple symbols with the same name.Chris Lattner2006-02-131-11/+52
| | | | llvm-svn: 26150
* Make the C writer work with packed types. printContainedStructs isRobert Bocchino2006-01-201-4/+49
| | | | | | still not quite right and will be fixed later. llvm-svn: 25488
* Simplify CWriter::printContainedStructs, also allowing it to work withChris Lattner2006-01-201-18/+11
| | | | | | PackedTypes as a side-effect. llvm-svn: 25485

* Add a new option to indicate we want the code generator to emit code ↵Chris Lattner2005-11-081-1/+1
| | | | | | quickly,not spending tons of time microoptimizing it. This is useful for an -O0style of build. llvm-svn: 24233

* Do not lower malloc's to pass "sizeof" expressions like this:Chris Lattner2005-03-031-1/+1
| | | | | | | | | | | | ltmp_0_7 = malloc(((unsigned )(&(((signed char (*)[784])/*NULL*/0)[1u])))); Instead, just emit the literal constant, like this: ltmp_0_7 = malloc(784u); This works around a bug in ICC 8.1 compiling the CBE generated code. :-( llvm-svn: 20415
