llvm 5.0 release rc1 : ExecutionEngine fatal error on MCJIT::getFunctionAddress
Hi everyone,
In llvm 4.0 the MCJIT::getFunctionAddress function return 0 (a null
address) when the symbol is not found :
*uint64_t MCJIT::getSymbolAddress(const std::string &Name, bool
CheckFunctionsOnly) { std::string MangledName; { raw_string_ostream
MangledNameStream(MangledName);
Mangler::getNameWithPrefix(MangledNameStream, Name, getDataLayout()); }
return findSymbol(MangledName, CheckFunctionsOnly).getAddress();}*
Now with the current implementation (llvm 5.0 rc1 tag) :
*uint64_t MCJIT::getSymbolAddress(const std::string &Name, bool
C...

MCJIT, can't use with math functions
...ath library (e.g. @cosf) it seems to
have problems getting the address after successfully finding the symbol:
Failure value returned from cantFail wrapped call
UNREACHABLE executed at
~/toolchain/install/llvm-8.0-x86-debug/include/llvm/Support/Error.h:732!
if (auto Sym = CompileLayer.findSymbol(MangledNameStream.str(),true))
{
void* fptr = (void *)cantFail(Sym.getAddress());
The last statement fails with the above message.
Has anything related to using MCJIT with math library functions changed
since LLVM 6.0?
Best,
Frank

[LLVMdev] Thoughts about ExecutionEngine/MCJIT interface
Hi,
I think ExecutionEngine as a common interface for both Interpreter and
MCJIT is almost useless in the current form. There are separated methods in
ExecutionEngine for similar or the same features provided by Interpreter
and MCJIT, i.e. to get a pointer to function you should call
getPointerToFunction() for Interpreter or getFunctionAddress() for MCJIT.
Personally, I'm using MCJIT and
