[LLVMdev] How to set constant pool section?

[Konstantin Vladimirov]

Hi,

Thanks for pointing direction. As far, as I understand by reversing,
logic, that I want to overwrite is digged into:

lib/MC/MCSectionELF.cpp

MCSectionELF::PrintSwitchToSection

  if (ShouldOmitSectionDirective(SectionName, MAI)) {
    OS << '\t' << getSectionName() << '\n';
    return;
  }

// otherwise print ".section" directive and then section name

So I need to overwrite ShouldOmitSectionDirective behavior. But this
method of MCSectionELF is not virtual.
As a workaround, I stubbed it in core LLVM code
(MCSectionELF::ShouldOmitSectionDirective), and everything works, but
it is ugly. May be you can advise further?

With best regards, Konstantin
