* Revert r124611 - "Keep track of incoming argument's location while emitting ↵Devang Patel2011-02-211-12/+12
| | | | | | | | | | | LiveIns." In other words, do not keep track of argument's location. The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body. This requires some coordination with debugger to get this working. - The debugger needs to be aware of prolog_end attribute attached with line table entries. - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+) llvm-svn: 126155

* Various bits of framework needed for precise machine-level selectionAndrew Trick2010-12-245-13/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | DAG scheduling during isel. Most new functionality is currently guarded by -enable-sched-cycles and -enable-sched-hazard. Added InstrItineraryData::IssueWidth field, currently derived from ARM itineraries, but could be initialized differently on other targets. Added ScheduleHazardRecognizer::MaxLookAhead to indicate whether it is active, and if so how many cycles of state it holds. Added SchedulingPriorityQueue::HasReadyFilter to allowing gating entry into the scheduler's available queue. ScoreboardHazardRecognizer now accesses the ScheduleDAG in order to get information about it's SUnits, provides RecedeCycle for bottom-up scheduling, correctly computes scoreboard depth, tracks IssueCount, and considers potential stall cycles when checking for hazards. ScheduleDAGRRList now models machine cycles and hazards (under flags). It tracks MinAvailableCycle, drives the hazard recognizer and priority queue's ready filter, manages a new PendingQueue, properly accounts for stall cycles, etc. llvm-svn: 122541

* There are two reasons why we might want to useRafael Espindola2010-12-041-0/+4
| | | | | | | | | | | | | | | | foo = a - b .long foo instead of just .long a - b First, on darwin9 64 bits the assembler produces the wrong result. Second, if "a" is the end of the section all darwin assemblers (9, 10 and mc) will not consider a - b to be a constant but will if the dummy foo is created. Split how we handle these cases. The first one is something MC should take care of. The second one has to be handled by the caller. llvm-svn: 120889

* Wire up primitive support in the assembler backend for writing .o filesChris Lattner2010-11-155-1/+137
| | | | | | | | | | | | | | directly on the mac. This is very early, doesn't support relocations and has a terrible hack to avoid .machine from being printed, but despite that it generates an bitwise-identical-to-cctools .o file for stuff like this: define i32 @test() nounwind { ret i32 42 } I don't plan to continue pushing this forward, but if anyone else was interested in doing it, it should be really straight-forward. llvm-svn: 119136
* split out an encoder for memri operands, allowing a relocation to be ploppedChris Lattner2010-11-155-58/+68
| | | | | | | | | | | | | | | | into the immediate field. This allows us to encode stuff like this: lbz r3, lo16(__ZL4init)(r4) ; globalopt.cpp:5 ; encoding: [0x88,0x64,A,A] ; fixup A - offset: 0, value: lo16(__ZL4init), kind: fixup_ppc_lo16 stw r3, lo16(__ZL1s)(r5) ; globalopt.cpp:6 ; encoding: [0x90,0x65,A,A] ; fixup A - offset: 0, value: lo16(__ZL1s), kind: fixup_ppc_lo16 With this, we should have a completely function MCCodeEmitter for PPC, wewt. llvm-svn: 119134
* add support for encoding the lo14 forms used for a few PPC64 addressingChris Lattner2010-11-155-25/+45
| | | | | | | | | modes. For example, we now get: ld r3, lo16(_G)(r3) ; encoding: [0xe8,0x63,A,0bAAAAAA00] ; fixup A - offset: 0, value: lo16(_G), kind: fixup_ppc_lo14 llvm-svn: 119133
* fix a regression with the new instprinter: we lost the ability toChris Lattner2010-11-151-0/+22

* change direct branches to encode with the same encoding methodChris Lattner2010-11-153-23/+38
| | | | | | | | as direct calls. Change conditional branches to encode with their own method, simplifying the JIT encoder and making room for adding an mc fixup. llvm-svn: 119125
