[lldb-dev] How is variable info retrieved in debugging for executables generated by llvm backend?

[杨勇勇]

Thank you, Clayton. It works now!

Our debugger server responds
"name:J28;generic:fp;bitsize:32;encoding:uint;format:hex;gcc:60;dwarf:60".
And I also set other "generic" attributes like sp, pc, ra, arg1~arg8 to
related registers.

I dig a little and find llvm dwarf generator uses
TargetRegisterInfo::getFrameRegister() to obtain frame base, and uses
TargetFrameLowering::getFrameIndexReference() to obtain frame base as well
as frame offset of a variable.

lldb is OK to check value of variable including both formal arguments and
locals, although some line numbers are still improper.
For example, in the case mentioned above, ".loc 1 2 0 prologue_end" is
actually the start point of prologue. Any suggestions?

Best regards.
