* Tweak cross-class coalescing to be more aggressive when the target class is ↵Jakob Stoklund Olesen2011-05-171-3/+9
| | | | | | | | | | | | | small. The greedy register allocator has live range splitting and register class inflation, so it can actually fully undo this join, including restoring the original register classes. We still don't want to do this for long live ranges, mostly because of the high register pressure of there are many constrained live ranges overlapping. llvm-svn: 131466

* Fix a bug in PerformEXTRACT_VECTOR_ELTCombine. The code created an ADD SDNodeNadav Rotem2011-05-171-2/+2

* Teach LiveInterval::isZeroLength about null SlotIndexes.Jakob Stoklund Olesen2011-05-161-1/+1
| | | | | | | | | | | | When instructions are deleted, they leave tombstone SlotIndex entries. The isZeroLength method should ignore these null indexes. This causes RABasic to sometimes spill a callee-saved register in the abi-isel.ll test, so don't run that test with -regalloc=basic. Prioritizing register allocation according to spill weight can cause more registers to be used. llvm-svn: 131436

| | | | llvm-svn: 131419
* Basic fast-isel of extractvalue. Not too helpful on its own, given the IR ↵Eli Friedman2011-05-161-0/+42
| | | | | | clang generates for cases like this, but it should become more useful soon. llvm-svn: 131417

| | | | | | | | | | ("T is 1 if the target symbol S has type STT_FUNC and the symbol addresses a Thumb instruction ;it is 0 otherwise." from "ELF for the ARM Architecture" 4.7.1.2) Patch by Koan-Sin Tan! llvm-svn: 131406
* Extra refactoring noticed by Eli Friedman.Rafael Espindola2011-05-161-9/+8
| | | | llvm-svn: 131405
* Don't do tail calls in a function that call setjmp. The stack might beRafael Espindola2011-05-163-37/+39

| | | | | | intrinsic from the x86 code to the generic code. llvm-svn: 131332
* Don't produce a vmovntdq if we don't have AVX support.Rafael Espindola2011-05-141-1/+1
| | | | llvm-svn: 131330
* Zap useless code; this hasn't done anything useful since fast-isel switched ↵Eli Friedman2011-05-141-29/+0
| | | | | | to being bottom-up (a very long time ago). llvm-svn: 131329
* Be a bit more permissive about symbols we don't understand. Just skip themJim Grosbach2011-05-131-4/+12
| | | | | | rather than throwing an error. llvm-svn: 131322
* ExecutionEngine: move createJIT() definition (v2)Dylan Noblesmith2011-05-132-19/+29
| | | | | | | As an ExecutionEngine class function, its definition really belongs in ExecutionEngine.cpp, not JIT.cpp. llvm-svn: 131320
* ExecutionEngine: push TargetMachine creation into clients (v2)Dylan Noblesmith2011-05-135-58/+28
| | | | | | | | In particular, into EngineBuilder. This should only impact the private API between the EE and EB classes, not external clients, since JITCtor and MCJITCtor are both protected members. llvm-svn: 131317
* ExecutionEngine: fix JIT/MCJIT selectTarget() duplication (v2)Dylan Noblesmith2011-05-139-117/+18
| | | | | | | This prepares for making JITCtor/MCJITCtor take a TargetMachine* directly from clients like EngineBuilder. llvm-svn: 131316
* Teach the RtDyld to tell the memory manager about how much space a functionJim Grosbach2011-05-131-3/+4
| | | | | | | actually takes rather than how much memory was allocated for it. This is more accurate and should help the manager pack things more effectively. llvm-svn: 131305
* Make codegen able to handle values of empty types. This is one wayRafael Espindola2011-05-133-6/+52

* Since I can't reproduce the failures from 131261, re-trying with aStuart Hastings2011-05-131-2/+6

* Non-fast-isel followup to 129634; correctly handle branches controlledStuart Hastings2011-05-121-2/+9
| | | | | | | | | | | | | by non-CMP expressions. The executable test case (129821) would test this as well, if we had an "-O0 -disable-arm-fast-isel" LLVM-GCC tester. Alas, the ARM assembly would be very difficult to check with FileCheck. The thumb2-cbnz.ll test is affected; it generates larger code (tst.w vs. cmp #0), but I believe the new version is correct. rdar://problem/9298790 llvm-svn: 131261

* MCJIT section loading should just skip non-text sections rather thanJim Grosbach2011-05-121-4/+4
| | | | | | | erroring out completely. Some modules produce sections that aren't referenced, so it's friendlier to clients like LLDB to just skip them, at least for now. llvm-svn: 131243
