2006-05-02Remove some stuff from the READMENate Begeman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28063 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-02Do not make the JIT memory manager manage the memory for globals. InsteadChris Lattner
just have the JIT malloc them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28062 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-02Minor cleanups, no functionality change.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28061 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-02Fix a purely hypothetical problem (for now): emitWord emits in the hostChris Lattner
byte format. This doesn't work when using the code emitter in a cross target environment. Since the code emitter is only really used by the JIT, this isn't a current problem, but if we ever start emitting .o files, it would be. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28060 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-02Refactor the machine code emitter interface to pull the pointers for the currentChris Lattner
code emission location into the base class, instead of being in the derived classes. This change means that low-level methods like emitByte/emitWord now are no longer virtual (yaay for speed), and we now have a framework to support growable code segments. This implements feature request #1 of PR469. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28059 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-02Extend printBasicBlockLabel a bit so that it can be used to print allNate Begeman
basic block labels, consolidating the code to do so in one place for each target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28050 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-01Fix a latent bug that my spiller patch last week exposed: we were leavingChris Lattner
instructions in the virtregfolded map that were deleted. Because they were deleted, newly allocated instructions could end up at the same address, magically finding themselves in the map. The solution is to remove entries from the map when we delete the instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28041 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-01Bottom up register-pressure reduction scheduler now pushes store operationsEvan Cheng
up the schedule. This helps code that looks like this: loads ... computations (first set) ... stores (first set) ... loads computations (seccond set) ... stores (seccond set) ... Without this change, the stores and computations are more likely to interleave: loads ... loads ... computations (first set) ... computations (second set) ... computations (first set) ... stores (first set) ... computations (second set) ... stores (stores set) ... This can increase the number of spills if we are unlucky. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28033 91177308-0d34-0410-b5e6-96231b3b80d8

2006-04-30Local spiller kills a store if the folded restore is turned into a copy.Evan Cheng
But this is incorrect if the spilled value live range extends beyond the current BB. It is currently controlled by a temporary option -spiller-check-liveout. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28024 91177308-0d34-0410-b5e6-96231b3b80d8

node can be folded. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28003 91177308-0d34-0410-b5e6-96231b3b80d8
2006-04-28When we have a two-address instruction where the input cannot be clobberedChris Lattner
and is already available, instead of falling back to emitting a load, fall back to emitting a reg-reg copy. This generates significantly better code for some SSE testcases, as SSE has lots of two-address instructions and none of them are read/modify/write. As one example, this change does: pshufd %XMM5, XMMWORD PTR [%ESP + 84], 255 xorps %XMM2, %XMM5 cmpltps %XMM1, %XMM0 - movaps XMMWORD PTR [%ESP + 52], %XMM0 - movapd %XMM6, XMMWORD PTR [%ESP + 52] + movaps %XMM6, %XMM0 cmpltps %XMM6, XMMWORD PTR [%ESP + 68] movapd XMMWORD PTR [%ESP + 52], %XMM6 movaps %XMM6, %XMM0 cmpltps %XMM6, XMMWORD PTR [%ESP + 36] cmpltps %XMM3, %XMM0 - movaps XMMWORD PTR [%ESP + 20], %XMM0 - movapd %XMM7, XMMWORD PTR [%ESP + 20] + movaps %XMM7, %XMM0 cmpltps %XMM7, XMMWORD PTR [%ESP + 4] movapd XMMWORD PTR [%ESP + 20], %XMM7 cmpltps %XMM4, %XMM0 ... which is far better than a store followed by a load! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28001 91177308-0d34-0410-b5e6-96231b3b80d8
