* Implement a special algorithm for converting uint_to_fp for i32 values onBill Wendling2009-01-172-49/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | X86. This code: void f() { uint32_t x; float y = (float)x; } used to be: movl %eax, -8(%ebp) movl [2^52 double], -4(%ebp) movsd -8(%ebp), %xmm0 subsd [2^52 double], %xmm0 cvtsd2ss %xmm0, %xmm0 Is now: movsd [2^52 double], %xmm0 movsd %xmm0, %xmm1 movd %ecx, %xmm2 orps %xmm2, %xmm1 subsd %xmm0, %xmm1 cvtsd2ss %xmm1, %xmm0 This is faster on X86. Note that there's an extra load of %xmm0 into %xmm1. That will be fixed in a later coalescer fix. llvm-svn: 62404

* Fix PPC ISD::Declare isel and eliminate the need for ↵Evan Cheng2009-01-162-4/+21
| | | | | | PPCTargetLowering::LowerGlobalAddress to check if isVerifiedDebugInfoDesc() is true. Given the recent changes, it would falsely return true for a lot of GlobalAddressSDNode's. llvm-svn: 62373
* Support for multi-valued options in CommandLineMikhail Glushenkov2009-01-161-4/+40
| | | | | | | Makes possible to specify options that take multiple arguments (a-la -sectalign on Darwin). See documentation for details. llvm-svn: 62372
* Give IA64 a TargetSubtarget subclass, so that it canDan Gohman2009-01-163-0/+49
| | | | | | implement getSubtargetImpl. llvm-svn: 62369
* Instead of adding dependence edges between terminator instructionsDan Gohman2009-01-166-25/+65
| | | | | | | | | | | | | | and every other instruction in their blocks to keep the terminator instructions at the end, teach the post-RA scheduler how to operate on ranges of instructions, and exclude terminators from the range of instructions that get scheduled. Also, exclude mid-block labels, such as EH_LABEL instructions, and schedule code before them separately from code after them. This fixes problems with the post-RA scheduler moving code past EH_LABELs. llvm-svn: 62366
* If an anti-dependence uses a non-allocatable register, set AntiDepRegDan Gohman2009-01-161-1/+3
| | | | | | | to 0, to ensure that the subsequent code doesn't try to break the dependence. llvm-svn: 62365
* Use the getNode() accessor instead of accessing the NodeDan Gohman2009-01-161-1/+1
| | | | | | member directly, which is private as of r55504. llvm-svn: 62364
* Fix the check for an empty basic block to check for an empty SUnitsDan Gohman2009-01-161-2/+2
| | | | | | | | array instead, since this is what the scheduler actually cares about. And remove a check that is unnecessary, since it can assume that SUnits isn't empty. llvm-svn: 62362
* new nodes should be added to the worklist, not old nodes.Chris Lattner2009-01-161-1/+2

* Fix comments.Devang Patel2009-01-161-5/+5

* CreateVirtualRegisters does trivial copy coalescing. If a node def is used ↵Evan Cheng2009-01-162-56/+63
| | | | | | by a single CopyToReg, it reuses the virtual register assigned to the CopyToReg. This won't work for SDNode that is a clone or is itself cloned. Disable this optimization for those nodes or it can end up with non-SSA machine instructions. llvm-svn: 62356
* don't assert and die on out of range (undefined) shifts. This fixesChris Lattner2009-01-161-4/+16

* Use lightweight DebugInfo objects directly.Devang Patel2009-01-161-51/+50
| | | | llvm-svn: 62341
* Add support for non-zero __builtin_return_address values on X86.Bill Wendling2009-01-161-8/+17
| | | | llvm-svn: 62338
* Change isGVCompilationDisabled() semantics again. It should abort on any GV ↵Evan Cheng2009-01-161-1/+4
| | | | | | that's not constant whether it's "internal" or not. In a server / client environment, GV is returned in the same block of memory as code. However, the memory might not be writable. llvm-svn: 62336

* Fix a "comparison between signed and unsigned integer expressions"Dan Gohman2009-01-161-1/+1

* Reinstate r60509 from Dale:Nick Lewycky2009-01-161-0/+1
| | | | | | Make the debugging dump be a full line. llvm-svn: 62325
* Registry.h should not depend on CommandLine.h.Mikhail Glushenkov2009-01-165-1/+6
| | | | | | | Split Support/Registry.h into two files so that we have less to recompile every time CommandLine.h is changed. llvm-svn: 62312
* Delete trailing whitespace.Mikhail Glushenkov2009-01-165-325/+325

* ARMCompilationCallback should not save / restore vfp registers if vfp is not ↵Evan Cheng2009-01-161-2/+2

* Validate debug info values only if DwarfDebug is initialized.Devang Patel2009-01-161-1/+1
| | | | llvm-svn: 62298
* Clean up previous cast optimization a bit. Also make zext elimination a bit ↵Evan Cheng2009-01-161-30/+55
| | | | | | more aggressive: if it's not necessary to emit an AND (i.e. high bits are already zero), it's profitable to evaluate the operand at a different type. llvm-svn: 62297
* Any debug info symbol is only valid if atleast one compile unit is seen.Devang Patel2009-01-161-0/+4
| | | | llvm-svn: 62294
* Initial hazard recognizer support in post-pass scheduling. This includesDan Gohman2009-01-164-14/+120
| | | | | | | a new toy hazard recognizier heuristic which attempts to direct the scheduler to avoid clumping large groups of loads or stores too densely. llvm-svn: 62291
* Do not stumble over forward declared struct member. Devang Patel2009-01-161-0/+5
| | | | llvm-svn: 62288
* Validate dbg_* intrinsics before lowering them.Devang Patel2009-01-153-10/+55
| | | | llvm-svn: 62286
* Added missing support to widen an operand from a bit convert.Mon P Wang2009-01-152-0/+32
| | | | llvm-svn: 62285
* Generalize the HazardRecognizer interface so that it can be usedDan Gohman2009-01-159-42/+40
| | | | | | | to support MachineInstr-based scheduling in addition to SDNode-based scheduling. llvm-svn: 62284
* Simplify the MachineLICM pass by having it only traverse outerDan Gohman2009-01-151-122/+60
| | | | | | | | | loops, hoisting instructions all the way out in one step rather than hoisting them one nest level at a time. Also, make a few other code simplifications. This speeds up MachineLICM by several fold. llvm-svn: 62283
* Fix Alpha test and support for private linkage.Rafael Espindola2009-01-151-1/+2
| | | | llvm-svn: 62282
