Using an MCStreamer Directly to produce an object file?
...".o" would be just fine to start with.
I seem to be able to create an aarch64 target without too much issue:
llvm::InitializeAllTargetInfos();
llvm::InitializeAllTargetMCs();
llvm::InitializeAllAsmParsers();
llvm::InitializeAllDisassemblers();
std::string Error;
std::string TripleName("aarch64-unknown-linux-gnu");
Triple TheTriple(Triple::normalize(TripleName));
const Target *TheTarget = TargetRegistry::lookupTarget(TripleName,
Error);
if (!TheTarget) {
std::cerr << "llvm_insts_to_binary(): " << Error;
return 1;
}
Then, I move on...

[LLVMdev] typeinfo for llvm::MCAsmInfo is missing
...I fully understand that the problem is a bit OT for llvmdev, but I'm stuck for two days now and I really need some direct push.
To the problem. I have a C++ shared library, that's working with llvm C++ api. Consider a function:
static Object llvm_Target_createMCAsmInfo(Object self, Object tripleName)
{
llvm::Target target = from_ruby<llvm::Target>(self);
char const *triple = from_ruby<char const *>(tripleName);
llvm::MCAsmInfo *MAI = target.createMCAsmInfo(triple);
return to_ruby<llvm::MCAsmInfo>(*MAI);
}
The problem here, is it's ok to use llvm::MCAsmInfo objects,...

[LLVMdev] Looking for ideas on how to make llvm-objdump handle both arm and thumb disassembly from the same object file
...r suggestions.
First a little back ground, the way darwin’s otool(1) does this is that it creates an llvm disassembler for both arm and thumb when disassembling a binary with 32-bit ARM cpu. It uses the C API in <llvm-c/Disassembler.h> and calls LLVMCreateDisasmCPU() twice, once with an arm TripleName and once with a matching thumb TripleName. Then for each 32-bit ARM cpu it will default to one or the other disassembler. Then as it disassembles and finds a symbol in the symbol table for the current PC being disassembled it will see of the symbol has the N_ARM_THUMB_DEF bit set or not. And the...

Problems using LLVM as a disassembler.
...a PC (program counter) parameter that worked. You
could use the PC as an offset within the buffer to start disassembling
from.
In LLVM 4.0 and above the only value of the PC parameter that works is zero.
Please can someone look into fixing this?
Kind Regards
James
P.S. Example code below:
TripleName = "x86_64-pc-linux-gnu";
// Get the target.
std::string Error;
DecodeAsmX86_64::TheTarget =
llvm::TargetRegistry::lookupTarget(TripleName, Error);
if (!TheTarget)
return 1;
...
// Set up disassembler.
DisAsm = TheTarget->createMCDisassembler(*STI, *Ctx);...
