Building mcsema with clang12 error about mcsema HOT 10 CLOSED

You can patch the source by replacing createConstantPropagationPass with createInstSimplifyPass

This is an LLVM API change, I thought it was in 13, not 12 though.

got this error

simply removed that optimization and it compiles.

// fpm.add(llvm::createInstSimplifyPass());

Also "getTypeByName" is not in "llvm::Module" it seems? https://reviews.llvm.org/D78793

had to remove this code to get it compiling on llvm 12.

  auto seg_type = gModule->getTypeByName(type_name);
  if (seg_type) {
    return seg_type;
  }

@michaelbrownuc
any updates on issue?
I tried build latest version(82c3106) but error still occur. File compiles after removing optimization. But other error occurs.

After removing quotes and next try other error occur.

IIRC there are a few API changes to make, including the one in the second screenshot. In that case removing the -1 parameter should solve that compiler error.

@michaelbrownuc
now have this error

@michaelbrownuc now have this error

@invlpg seg_type is used and returned later in function GetSegmentType so just removing code doesnt work.

Line 106 in 87239ee

auto seg_type = gModule->getTypeByName(type_name);

  auto seg_type = gModule->getTypeByName(type_name);
  if (seg_type) {
    return seg_type;
  }

getTypeByName is moved to other place. Try this, it work for me

auto seg_type = llvm::StructType::getTypeByName(gModule->getContext(), type_name);

Thanks, it works.
