2009-08-11SjLj based exception handling unwinding support. This patch is nasty, brutishJim Grosbach
and short. Well, it's kinda short. Definitely nasty and brutish. The front-end generates the register/unregister calls into the SjLj runtime, call-site indices and landing pad dispatch. The back end fills in the LSDA with the call-site information provided by the front end. Catch blocks are not yet implemented. Built on Darwin and verified no llvm-core "make check" regressions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78625 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-25More migration to raw_ostream, the water has dried up around the iostream hole.Daniel Dunbar
- Some clients which used DOUT have moved to DEBUG. We are deprecating the "magic" DOUT behavior which avoided calling printing functions when the statement was disabled. In addition to being unnecessary magic, it had the downside of leaving code in -Asserts builds, and of hiding potentially unnecessary computations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77019 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-23Reverting r76825 and r76828, since they caused clang runtime errors and some ↵Reid Kleckner
build failure involving memset. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76838 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-23Make the JIT code emitter properly retry and ask for more memory when it runsReid Kleckner
out of memory, and also make the default memory manager allocate more memory when it runs out. Also, switch function stubs and global data over to using the BumpPtrAllocator. This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB of memory, and instead allocates in 512K slabs. I suspect this size could go lower, especially on embedded platforms, now that more slabs can be allocated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76828 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76553 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-16Add line numbers to OProfile. To do this, I added a processDebugLoc()Jeffrey Yasskin
call to the MachineCodeEmitter interface and made copying the start line of a function not conditional on whether we're emitting Dwarf debug information. I'll propagate the processDebugLoc() calls to the non-X86 targets in a followup patch. In the long run, it'll probably be better to gather this information through the DwarfWriter, but the DwarfWriter currently depends on the AsmPrinter and TargetAsmInfo, and fixing that would be out of the way for this patch. There's a bug in OProfile 0.9.4 that makes it ignore line numbers for addresses above 4G, and a patch fixing it at http://thread.gmane.org/gmane.linux.oprofile/7634 Sample output: $ sudo opcontrol --reset; sudo opcontrol --start-daemon; sudo opcontrol --start; `pwd`/Debug/bin/lli fib.bc; sudo opcontrol --stop Signalling daemon... done Profiler running. fib(40) == 165580141 Stopping profiling. $ opreport -g -d -l `pwd`/Debug/bin/lli|head -60 Overflow stats not available CPU: Core 2, speed 1998 MHz (estimated) Counted CPU_CLK_UNHALTED events (Clock cycles when not halted) with a unit mask of 0x00 (Unhalted core cycles) count 100000 vma samples % linenr info image name symbol name 00007f67a30370b0 25489 61.2554 fib.c:24 10946.jo fib_left 00007f67a30370b0 1634 6.4106 fib.c:24 00007f67a30370b1 83 0.3256 fib.c:24 00007f67a30370b9 1997 7.8348 fib.c:24 00007f67a30370c6 2080 8.1604 fib.c:27 00007f67a30370c8 988 3.8762 fib.c:27 00007f67a30370cd 1315 5.1591 fib.c:27 00007f67a30370cf 251 0.9847 fib.c:27 00007f67a30370d3 1191 4.6726 fib.c:27 00007f67a30370d6 975 3.8252 fib.c:27 00007f67a30370db 1010 3.9625 fib.c:27 00007f67a30370dd 242 0.9494 fib.c:27 00007f67a30370e1 2782 10.9145 fib.c:28 00007f67a30370e5 3768 14.7828 fib.c:28 00007f67a30370eb 615 2.4128 (no location information) 00007f67a30370f3 6558 25.7287 (no location information) 00007f67a3037100 15603 37.4973 fib.c:29 10946.jo fib_right 00007f67a3037100 1646 10.5493 fib.c:29 00007f67a3037101 45 0.2884 fib.c:29 00007f67a3037109 2372 15.2022 fib.c:29 00007f67a3037116 2234 14.3178 fib.c:32 00007f67a3037118 612 3.9223 fib.c:32 00007f67a303711d 622 3.9864 fib.c:32 00007f67a303711f 385 2.4675 fib.c:32 00007f67a3037123 404 2.5892 fib.c:32 00007f67a3037126 634 4.0633 fib.c:32 00007f67a303712b 870 5.5759 fib.c:32 00007f67a303712d 62 0.3974 fib.c:32 00007f67a3037131 1848 11.8439 fib.c:33 00007f67a3037135 2840 18.2016 fib.c:33 00007f67a303713a 1 0.0064 fib.c:33 00007f67a303713b 1023 6.5564 (no location information) 00007f67a3037143 5 0.0320 (no location information) 000000000080c1e4 15 0.0360 MachineOperand.h:150 lli llvm::MachineOperand::isReg() const 000000000080c1e4 6 40.0000 MachineOperand.h:150 000000000080c1ec 2 13.3333 MachineOperand.h:150 ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76102 91177308-0d34-0410-b5e6-96231b3b80d8

Patch by Reid Kleckner! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75059 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-25Add a JITEventListener interface that gets called back when a new function isJeffrey Yasskin
emitted or the machine code for a function is freed. Chris mentioned that we may also want a notification when a stub is emitted, but that'll be a future change. I intend to use this to tell oprofile where functions are emitted and what lines correspond to what addresses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74157 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman
integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately.

code. Introduce a new class (MachineCodeInfo) that the JIT can fill in with details. Right now, just the address and the size of the machine code are reported. Patch by Evan Phoenix! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72040 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-27Under unusual circumstances (jitting a function that causes the creation ofNick Lewycky
another stub, but then never calling the jitted function) can cause the JIT to leave a stub in place. Judging by the comments this is a known deficiency, so we're just not going to use AssertingVH for the StubToFunctionTy map. Also shorten some lines longer than 80 columns. This fixes the "make check" failure with ocaml on x86-64 linux. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70185 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-13Fix some significant problems with constant pools that resulted in ↵Evan Cheng
unnecessary paddings between constant pool entries, larger than necessary alignments (e.g. 8 byte alignment for .literal4 sections), and potentially other issues. 1. ConstantPoolSDNode alignment field is log2 value of the alignment requirement. This is not consistent with other SDNode variants. 2. MachineConstantPool alignment field is also a log2 value. 3. However, some places are creating ConstantPoolSDNode with alignment value rather than log2 values. This creates entries with artificially large alignments, e.g. 256 for SSE vector values. 4. Constant pool entry offsets are computed when they are created. However, asm printer group them by sections. That means the offsets are no longer valid. However, asm printer uses them to determine size of padding between entries. 5. Asm printer uses expensive data structure multimap to track constant pool entries by sections. 6. Asm printer iterate over SmallPtrSet when it's emitting constant pool entries. This is non-deterministic. Solutions: 1. ConstantPoolSDNode alignment field is changed to keep non-log2 value. 2. MachineConstantPool alignment field is also changed to keep non-log2 value. 3. Functions that create ConstantPool nodes are passing in non-log2 alignments. 4. MachineConstantPoolEntry no longer keeps an offset field. It's replaced with an alignment field. Offsets are not computed when constant pool entries are created. They are computed on the fly in asm printer and JIT. 5. Asm printer uses cheaper data structure to group constant pool entries. 6. Asm printer compute entry offsets after grouping is done. 7. Change JIT code to compute entry offsets on the fly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66875 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-11Allow cross-process JIT to handle MachineRelocations of the ExternalSymbolNate Begeman
variety. For example, an i64 div might turn into a call to __divdi3 during legalization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66646 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-07Finish cross-process JIT work, and clean up previous work.Nate Begeman
1. When the JIT is asked to remove a function, updating it's mapping to 0, we invalidate any function stubs used only by that function. Now, also invalidate the JIT's mapping from the GV the stub pointed to, to the address of the GV. 2. When dlsym stubs for cross-process JIT are enabled, do not abort just because a named function cannot be found in the JIT's process. 3. Fix various assumptions about when it is ok to use the lazy resolver when non-lazy JITing is enabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66324 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-05When allocating stubs, keep track of which Functions are referencing the stub.Nate Begeman
This invalidates the stubs in the resolver map when they are no longer referenced, and should the JIT memory manager ever pick up a deallocateStub interface, the JIT could reclaim the memory for unused stubs as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66141 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Fix a thinko in the JIT where the address of a GV was only recorded in the mapNate Begeman
on failure to resolve it. Do not abort on failure to resolve an external symbol when using dlsym stubs, since the symbol may not be in the JIT's address space. Just use 0. Allow dlsym stubs to differentiate between GlobalVars and Functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66050 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-02Fix the calculation for how big the allocated stub needs to be.Nate Begeman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65895 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-18Add support to the JIT for true non-lazy operation. When a call to a functionNate Begeman
that has not been JIT'd yet, the callee is put on a list of pending functions to JIT. The call is directed through a stub, which is updated with the address of the function after it has been JIT'd. A new interface for allocating and updating empty stubs is provided. Add support for removing the ModuleProvider the JIT was created with, which would otherwise invalidate the JIT's PassManager, which is initialized with the ModuleProvider's Module. Add support under a new ExecutionEngine flag for emitting the infomration necessary to update Function and GlobalVariable stubs after JITing them, by recording the address of the stub and the name of the GlobalValue. This allows code to be copied from one address space to another, where libraries may live at different virtual addresses, and have the stubs updated with their new correct target addresses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64906 91177308-0d34-0410-b5e6-96231b3b80d8
