* Don't allow DBG_VALUE to affect codegen.Dale Johannesen2010-02-111-0/+3

* Use array_pod_sort instead of std::sort for improved code size.Jakob Stoklund Olesen2010-02-111-2/+2
| | | | | | | Use SmallVector instead of std::vector for better speed when indirectbr has few successors. llvm-svn: 95879
* Use .empty() instead of .size().Bill Wendling2010-02-111-2/+2

* Don't print out a default newline when emitting the section offset. There areBill Wendling2010-02-112-2/+1
| | | | | | almost always comments afterwards that need printing. llvm-svn: 95839
* Reuse operand location when updating PHI instructions.Jakob Stoklund Olesen2010-02-111-7/+26
| | | | | | | | Calling RemoveOperand is very expensive on huge PHI instructions. This makes early tail duplication run twice as fast on the Firefox JavaScript interpreter. llvm-svn: 95832
* Remove duplicate successors from indirectbr instructions before building the ↵Jakob Stoklund Olesen2010-02-111-2/+8
| | | | | | | | | machine CFG. This makes early tail duplication run 60 times faster when compiling the Firefox JavaScript interpreter, see PR6186. llvm-svn: 95831
* The previous fix of widening divides that trap was too fragile as it depends ↵Mon P Wang2010-02-102-3/+107
| | | | | | | | | | | on custom lowering and requires that certain types exist in ValueTypes.h. Modified widening to check if an op can trap and if so, the widening algorithm will apply only the op on the defined elements. It is safer to do this in widening because the optimizer can't guarantee removing unused ops in some cases. llvm-svn: 95823
* Ignore debug info one more place during coalescing.Dale Johannesen2010-02-101-0/+2
| | | | llvm-svn: 95819
* Delete dead PHI machine instructions. These can be created due to typeBob Wilson2010-02-101-1/+1
| | | | | | | | | legalization even when the IR-level optimizer has removed dead phis, such as when the high half of an i64 value is unused on a 32-bit target. I had to adjust a few test cases that had dead phis. This is a partial fix for Radar 7627077. llvm-svn: 95816
* Skip debug info in a couple of places.Dale Johannesen2010-02-101-3/+7
| | | | llvm-svn: 95814
* Use an index instead of pointers into the vector. If the vector resizes, thenBill Wendling2010-02-102-12/+13
| | | | | | the pointer values could be invalid. llvm-svn: 95813
* When I rewrote this loop per Chris' preference IDale Johannesen2010-02-101-0/+3
| | | | | | changed its behavior. Oops. llvm-svn: 95811
* Fix several comments which had previously been "the the" where aDan Gohman2010-02-101-1/+1
| | | | | | different word was intended. llvm-svn: 95795

| | | | | | leave some obvious nops which dag combine used to clean up afterwards e.g. (trunk (ext n)) -> n. Look for them and squash them. llvm-svn: 95757
* Rewrite loop to suit Chris' preference.Dale Johannesen2010-02-101-16/+19
| | | | llvm-svn: 95749
* fix a layering violation: VirtRegRewriter.cpp shouldn't use AsmPrinter.h.Chris Lattner2010-02-102-5/+4
| | | | llvm-svn: 95748
* Remove duplicated #include.Evan Cheng2010-02-101-1/+0
| | | | llvm-svn: 95747
* Emit an error for illegal inline asm constraint (which uses illegal type) ↵Evan Cheng2010-02-102-1/+14

* fix missing #includes.Chris Lattner2010-02-103-1/+3
| | | | llvm-svn: 95745
* Improve comments a even more.Bill Wendling2010-02-101-3/+3
| | | | llvm-svn: 95740
* Skip DBG_VALUE many places in live intervals andDale Johannesen2010-02-102-38/+57
| | | | | | | | | register coalescing. This fixes many crashes and places where debug info affects codegen (when dbg.value is lowered to machine instructions, which it isn't yet in TOT). llvm-svn: 95739
* Move verbose asm instruction comments to using MCStreamer.Chris Lattner2010-02-101-74/+61
| | | | | | | | | | | | The major win of this is that the code is simpler and they print on the same line as the instruction again: movl %eax, 96(%esp) ## 4-byte Spill movl 96(%esp), %eax ## 4-byte Reload cmpl 92(%esp), %eax ## 4-byte Folded Reload jl LBB7_86 llvm-svn: 95738

* more comment updatesDale Johannesen2010-02-101-2/+2
| | | | llvm-svn: 95736
* Add isDebug argument to ChangeToRegister; this preventsDale Johannesen2010-02-101-1/+3
| | | | | | the field from being used uninitialized later in some cases. llvm-svn: 95735
* print all the newlines at the end of instructions withChris Lattner2010-02-101-4/+6
| | | | | | OutStreamer.AddBlankLine instead of textually. llvm-svn: 95734
* Fix comments to reflect renaming elsewhere.Dale Johannesen2010-02-103-4/+4
| | | | llvm-svn: 95730
* Only dump output in debug mode.David Greene2010-02-091-4/+5
| | | | llvm-svn: 95711
* Improve comments in the LSDA somewhat. They can be improved much more.Bill Wendling2010-02-091-10/+17
| | | | llvm-svn: 95707
* move target-independent opcodes out of TargetInstrInfoChris Lattner2010-02-0937-213/+163
| | | | | | | | | into TargetOpcodes.h. #include the new TargetOpcodes.h into MachineInstr. Add new inline accessors (like isPHI()) to MachineInstr, and start using them throughout the codebase. llvm-svn: 95687
* Remember to update live-in lists when coalescing physregs.Jakob Stoklund Olesen2010-02-091-0/+17
| | | | | | Patch by M Wahab! llvm-svn: 95668
* Skip DEBUG_VALUE in some places where it was affecting codegen.Dale Johannesen2010-02-093-0/+9
| | | | llvm-svn: 95647
* Add declaration attribute to a variable DIE, if there is a separate DIE for ↵Devang Patel2010-02-091-0/+1
| | | | | | the definition. llvm-svn: 95646
* Fixed a bug in the PBQP allocator's findCoalesces method.Lang Hames2010-02-091-6/+17
| | | | | | Previously spill registers, whose def indexes are not defined, would sometimes be improperly marked as coalescable with conflicting registers. The new findCoalesces routine conservatively assumes that any register with at least one undefined def is not coalescable with any register it interferes with. llvm-svn: 95636
* Added copy sensible construction & assignment to PBQP graphs and fixed a ↵Lang Hames2010-02-092-18/+85
| | | | | | memory access bug in the heuristic solver. llvm-svn: 95633
* Implement AsmPrinter support for several more operators which haveDan Gohman2010-02-091-0/+10
| | | | | | | direct MCExpr equivalents. Don't use MCExpr::Shr because it isn't consistent between targets. llvm-svn: 95620
* now that @GOTOFF is no longer represented as a suffix on aChris Lattner2010-02-081-6/+4
| | | | | | | MCSymbol, we can remove the 'suffix' argument of GetBlockAddressSymbol. Do so. llvm-svn: 95601
* ConstantFoldConstantExpression can theoretically return the originalDan Gohman2010-02-081-2/+4
| | | | | | expression; don't go into an infinite loop if it does. llvm-svn: 95591
* When CodeGen'ing unoptimized code, there may be unfolded constant expressionsDan Gohman2010-02-081-9/+11
| | | | | | | | | in global initializers. Instead of aborting, attempt to fold them on the spot. If folding succeeds, emit the folded expression instead. This fixes PR6255. llvm-svn: 95583
* Apply the 95471 fix to SelectionDAGBuilder as well;Dale Johannesen2010-02-081-0/+2
| | | | | | | we can get in here if FastISel gives up in a block. (Actually the two copies of this need to be unified. Later.) llvm-svn: 95579
* In guaranteed tailcall mode, don't decline the tailcall optimizationDan Gohman2010-02-081-7/+10
| | | | | | for blocks ending in "unreachable". llvm-svn: 95565
* Give DwarfPrinter a protected (but not virtual) destructor. CppcheckDuncan Sands2010-02-071-0/+2
| | | | | | | | | warns about this base class not having a virtual destructor, but since this class has no virtual methods and neither it or the types derived from it has a destructor, a protected trivial destructor will do (and shuts cppcheck up) the trick without the cost of introducing a vtable. llvm-svn: 95526
* Run codegen dce pass for all targets at all optimization levels. Previously it'sEvan Cheng2010-02-063-0/+14
| | | | | | | | | | only run for x86 with fastisel. I've found it being very effective in eliminating some obvious dead code as result of formal parameter lowering especially when tail call optimization eliminated the need for some of the loads from fixed frame objects. It also shrinks a number of the tests. A couple of tests no longer make sense and are now eliminated. llvm-svn: 95493
