From a51245036e3f082da43f73c927383d00cfa4437c Mon Sep 17 00:00:00 2001 From: Misha Brukman Date: Fri, 6 Jun 2003 07:11:16 +0000 Subject: [PATCH] * Removed PreSelection pass because that is now done in the JIT * Removed instruction scheduling as it is too slow to run in a JIT environment * Removed other passes because they aren't necessary and can slow JIT down git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6652 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/SparcV9/SparcV9TargetMachine.cpp | 32 +++++++-------------- 1 file changed, 10 insertions(+), 22 deletions(-) diff --git a/lib/Target/SparcV9/SparcV9TargetMachine.cpp b/lib/Target/SparcV9/SparcV9TargetMachine.cpp index 1ad62aa821e..8472ce0929c 100644 --- a/lib/Target/SparcV9/SparcV9TargetMachine.cpp +++ b/lib/Target/SparcV9/SparcV9TargetMachine.cpp @@ -198,34 +198,24 @@ bool UltraSparc::addPassesToEmitAssembly(PassManager &PM, std::ostream &Out) // generation for the UltraSparc. // bool UltraSparc::addPassesToJITCompile(PassManager &PM) { + const TargetData &TD = getTargetData(); + + PM.add(new TargetData("lli", TD.isLittleEndian(), TD.getPointerSize(), + TD.getPointerAlignment(), TD.getDoubleAlignment())); + + // Replace malloc and free instructions with library calls. + // Do this after tracing until lli implements these lib calls. + // For now, it will emulate malloc and free internally. + PM.add(createLowerAllocationsPass()); + // FIXME: implement the switch instruction in the instruction selector.
