2011-04-13Passing unroll parameters (unroll-count, threshold, and partial unroll) via ↵Junjie Gu
LoopUnroll class's ctor. Doing so will allow multiple context with different loop unroll parameters to run. This is a minor change and no effect on existing application. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129449 91177308-0d34-0410-b5e6-96231b3b80d8

Relocations between the object modules are properly resolved, as in the following trivial example: $ cat t.c int foo(); int main() { return foo(); } $ cat foo.c int foo() { return 65; } $ clang -c t.c -fno-asynchronous-unwind-tables $ clang -c foo.c -fno-asynchronous-unwind-tables $ llvm-rtdyld t.o foo.o ; echo $? loaded '_main' at: 0x10015c000 65 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129448 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-13Recommit r129383. PreRA scheduler heuristic fixes: VRegCycle, TokenFactor ↵Andrew Trick
latency. Additional fixes: Do something reasonable for subtargets with generic itineraries by handle node latency the same as for an empty itinerary. Now nodes default to unit latency unless an itinerary explicitly specifies a zero cycle stage or it is a TokenFactor chain. Original fixes: UnitsSharePred was a source of randomness in the scheduler: node priority depended on the queue data structure. I rewrote the recent VRegCycle heuristics to completely replace the old heuristic without any randomness. To make the ndoe latency adjustments work, I also needed to do something a little more reasonable with TokenFactor. I gave it zero latency to its consumers and always schedule it as low as possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129421 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-12MCJIT lazy relocation resolution and symbol address re-assignment.Jim Grosbach
Add handling for tracking the relocations on symbols and resolving them. Keep track of the relocations even after they are resolved so that if the RuntimeDyld client moves the object, it can update the address and any relocations to that object will be updated. For our trival object file load/run test harness (llvm-rtdyld), this enables relocations between functions located in the same object module. It should be trivially extendable to load multiple objects with mutual references. As a simple example, the following now works (running on x86_64 Darwin 10.6): $ cat t.c int bar() { return 65; } int main() { return bar(); } $ clang t.c -fno-asynchronous-unwind-tables -o t.o -c $ otool -vt t.o t.o: (__TEXT,__text) section _bar: 0000000000000000 pushq %rbp 0000000000000001 movq %rsp,%rbp 0000000000000004 movl $0x00000041,%eax 0000000000000009 popq %rbp 000000000000000a ret 000000000000000b nopl 0x00(%rax,%rax) _main: 0000000000000010 pushq %rbp 0000000000000011 movq %rsp,%rbp 0000000000000014 subq $0x10,%rsp 0000000000000018 movl $0x00000000,0xfc(%rbp) 000000000000001f callq 0x00000024 0000000000000024 addq $0x10,%rsp 0000000000000028 popq %rbp 0000000000000029 ret $ llvm-rtdyld t.o -debug-only=dyld ; echo $?
