2005-10-14Eliminate PowerPC.td and PPC32.td, consolidating them into PPC.tdChris Lattner

2005-10-01Modify the ppc backend to use two register classes for FP: F8RC and F4RC.Chris Lattner
These are used to represent float and double values, and the two regclasses contain the same physical registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23577 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-24Split IMPLICIT_DEF into IMPLICIT_DEF_GPR and IMPLICIT_DEF_FP, so that theChris Lattner
instructions take a consistent reg class. Implement ISD::UNDEF in the dag->dag selector to generate this, fixing UnitTests/2003-07-06-IntOverflow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23028 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-21Support building non-PICNate Begeman
Remove the LoadHiAddr pseudo-instruction. Optimization of stores to and loads from statics. Force JIT to use new non-PIC codepaths. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22494 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-19Add completely untested support for mtcrf/mfcrf encodingChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21353 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-18Handle ExternalSymbol operands in the PPC JITChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21312 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-25Enable optimization suggested by Chris Lattner to not emit reloc stubs forNate Begeman
static global variables whose addresses are taken. This allows us to convert the following code for taking the address of a static function foo addis r2, r30, ha16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb") lwz r3, lo16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")(r2) which also includes linker stub code emitted at the end of the .s file not shown here, and replace it with this: addis r2, r30, ha16(l1__2E_foo_2-"L00001$pb") la r3, lo16(l1__2E_foo_2-"L00001$pb")(r2) which in addition to not needing linker help, also has no load instruction. For those not up on PowerPC mnemonics, la is shorthand for add immediate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18239 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-25There is not a 1-1 mappign between llvm blocks and PPC blocks, do not useChris Lattner
LLVM blocks as the keys for the branch rewriter. This fixes treeadd and many other programs with the JIT. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18223 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-24* Rename existing relocations to be more specificChris Lattner
* Add relocations for refernces to non-lazy darwin stubs and implement them correctly. With this change, we can correctly references external globals, and now all but two UnitTests and all but 1 Regression/C tests pass. More importantly, bugpoint-jit will start giving us useful testcases, instead of always telling us that references to external globals don't work :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18222 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-24Loads are relocatable tooChris Lattner

2004-11-24Calls do not need a MovPCtoLR instructionChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18197 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-24Get constant pools working. This fixes even more programs, allowing us toChris Lattner
pass 24/42 in UnitTests (up from 20). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18196 91177308-0d34-0410-b5e6-96231b3b80d8
2004-11-24Rewrite branches more closely to correct. This makes more stuff pass, andChris Lattner
stops the infinite loops! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18194 91177308-0d34-0410-b5e6-96231b3b80d8

2004-11-23Emit relocations for the global variable using instructions. This gets usChris Lattner
LA, LOADHiAddr, CALLpcrel, and MovePCtoLR working, though the constant pool probably is not right. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18144 91177308-0d34-0410-b5e6-96231b3b80d8
