...le to ppc64le, but the "step over"
is not working for some cases.
When debugging, I can see that the disassembler analyze some instructions
forward, looking for a branch instruction
(llvm/tools/lldb/source/Plugins/Disassembler/llvm/DisassemblerLLVMC.cpp:87
- "const bool can_branch = mc_disasm_ptr->CanBranch(inst);"), while
trying to set the next breakpoint.
On this case, the instruction is the "bne cr7,0x2000092c", which is a branch,
but at llvm/lib/MC/MCInstrDesc.cpp:35 -
"if (isBranch() || isCall() || isReturn() || isIndirectBranch())" it returns false,
