[LLVMdev] LLVM 3.3 JIT code speed
...n?
I tried to play with TargetOptions without any success…
Here is the kind of code we use to allocate the JIT:
EngineBuilder builder(fResult->fModule);
builder.setOptLevel(CodeGenOpt::Aggressive);
builder.setEngineKind(EngineKind::JIT);
builder.setUseMCJIT(true);
builder.setCodeModel(CodeModel::JITDefault);
builder.setMCPU(llvm::sys::getHostCPUName());
TargetOptions targetOptions;
targetOptions.NoFramePointerElim = true;
targetOptions.LessPreciseFPMADOption = true;
targetOptions.UnsafeFPMath = true;
targetOptions.NoInfsFPMath = true;

Position independent code writes absolute pointer
...t;The magic value is %i 0x%p && 0x%p\n", magicValue, &magicValue, pValue);
}
void setMagicValue(int value)
{
magicValue = value;
}
This is the code which I will load as PIC, for the JTMB I use the following settings:
JTMB->setRelocationModel(llvm::Reloc::PIC_);
JTMB->setCodeModel(llvm::CodeModel::Small);
The code will be loaded into a shared memory. Two process will execute the memory from there, calling "printMagicValue", "setMagicValue(120)" and "printMagicValue" again. Only the first process will JIT the code, every other process will access...

[LLVMdev] [MCJIT] Why does it produce non-PIC ELF code?
ELF that MCJIT writes on x86_64 has relocations in it. Particularly,
R_X86_64_PC32 relocations are used for the sections .gcc_except_table
and .eh_frame related to exception processing.
I am not sure where is general documentation on relocation types,
including R_X86_64_PC32. Looks like it's nowhere to be found on the web.
But 32-bit relocation can't be used in 64-bit code since it
