...- "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,
making lldb do not set the correct breakpoint, so the execution does not stop
at next line, which should be the "step over" behavior.
The variable "Flags" for the disassembled instruction does not have the branch
flag.
I have tried to change the file...
