Hi,

Due to a Debian build failure of Postgres, which uses LLVM for JIT compilation,
I noticed that the sparc target claims to have JIT support, but does not
actually support JIT compilation:

llvm/lib/Target/Sparc/TargetInfo/SparcTargetInfo.cpp :
extern "C" LLVM_EXTERNAL_VISIBILITY void LLVMInitializeSparcTargetInfo() {
  RegisterTarget<Triple::sparc, /*HasJIT=*/true> X(getTheSparcTarget(),
"sparc",
                                                   "Sparc", "Sparc");
  RegisterTarget<Triple::sparcv9, /*HasJIT=*/true> Y(
      getTheSparcV9Target(), "sparcv9", "Sparc V9", "Sparc");
  RegisterTarget<Triple::sparcel, /*HasJIT=*/true> Z(
      getTheSparcelTarget(), "sparcel", "Sparc LE", "Sparc");
}

but there's no relocation processing support at all:

llvm/lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp
void RuntimeDyldELF::resolveRelocation(const SectionEntry &Section,
                                       uint64_t Offset, uint64_t Value,
                                       uint32_t Type, int64_t Addend,
                                       uint64_t SymOffset, SID SectionID) {

So it appears that HasJIT should be set to false instead?

Regards,

Andres
