2010-05-22Implement eh.sjlj.longjmp for ARM. Clean up the intrinsic a bit.Jim Grosbach
Followups: docs patch for the builtin and eh.sjlj.setjmp cleanup to match longjmp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104419 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-22Recognize more BUILD_VECTORs and VECTOR_SHUFFLEs that can be implemented byBob Wilson
copying VFP subregs. This exposed a bunch of dead code in the *spill-q.ll tests, so I tweaked those tests to keep that code from being optimized away. Radar 7872877. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104415 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-21Change ARM scheduling default to list-hybrid if the target supports floating ↵Evan Cheng
point instructions (and is not using soft float). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104307 91177308-0d34-0410-b5e6-96231b3b80d8

what for latency in hybrid mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104293 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-20Handle Neon v2f64 and v2i64 vector shuffles as register copies.Bob Wilson
This fixes the remaining issue with pr7167. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104257 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-19Code refactoring: pull SchedPreference enum from TargetLowering.h to ↵Evan Cheng
TargetMachine.h and put it in its own namespace. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104147 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-18Sink dag combine's post index load / store code that swap base ptr and index ↵Evan Cheng
into the target hook. Only the target knows whether the swap is safe. In Thumb2 mode, the offset must be an immediate. rdar://7998649 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104060 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-15Some cheap DAG combine goodness for multiplication with a particular constant.Anton Korobeynikov
This can be extended later on to handle more "complex" constants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103881 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-15Allow TargetLowering::getRegClassFor() to be called on illegal types. AlsoEvan Cheng
allow target to override it in order to map register classes to illegal but synthesizable types. e.g. v4i64, v8i64 for ARM / NEON. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103854 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-11Implement a bunch more TargetSelectionDAGInfo infrastructure.Dan Gohman
Move EmitTargetCodeForMemcpy, EmitTargetCodeForMemset, and EmitTargetCodeForMemmove out of TargetLowering and into SelectionDAGInfo to exercise this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103481 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-01Get rid of the EdgeMapping map. Instead, just check for BasicBlockDan Gohman
changes before doing phi lowering for switches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102809 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-17Use const qualifiers with TargetLowering. This eliminates severalDan Gohman
const_casts, and it reinforces the design of the Target classes being immutable. SelectionDAGISel::IsLegalToFold is now a static member function, because PIC16 uses it in an unconventional way. There is more room for API cleanup here. And PIC16's AsmPrinter no longer uses TargetLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101635 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-17Revise my previous change to ExpandBIT_CONVERT. I hadn't realized that thisBob Wilson
may be called when either the source or destination type is i64, and my change also hadn't fixed the most obvious problem -- assuming that i64 will only be bitconverted to f64, ignoring the various vector types.

2010-03-09The ARM EH experiment worked!Bill Wendling
Place the LSDA into the TEXT section for ARM platforms. This involves making the encoding indirect, pcrel, and sdata4 instead of an absolute pointer. The references to the type infos are then non-lazy pointers. Revision 98019 changed the encoding of non-lazy pointers to add the symbol to the non-lazy pointer definition if it's a local symbol (otherwise, it's external and set to '0' so that the loader can adjust it to the real value). This paved the way for this change to work on ARM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98068 91177308-0d34-0410-b5e6-96231b3b80d8
