proc: refactor stack.go to use DWARF registers Instead of only tracking a few cherrypicked registers in stack.go track all DWARF registers. This is needed for cgo code and for the locationlists emitted by go in 1.10: * The debug_frame sections emitted by C compilers can not be used without tracking all registers * the loclists emitted by go1.10 need all registers of a frame to be interpreted. 2017-10-05 07:26:19 +00:00			`import (`
*: Update import name to github.com/go-delve/delve The repository is being switched from the personal account github.com/derekparker/delve to the organization account github.com/go-delve/delve. This patch updates imports and docs, while preserving things which should not be changed such as my name in the CHANGELOG and in TODO comments. 2019-01-04 18:39:25 +00:00			`"github.com/go-delve/delve/pkg/dwarf/frame"`

proc: support cgo stacktraces When creating a stack trace we should switch between the goroutine stack and the system stack (where cgo code is executed) as appropriate to reconstruct the logical stacktrace. Goroutines that are currently executing on the system stack will have the SystemStack flag set, frames of the goroutine stack will have a negative FrameOffset (like always) and frames of the system stack will have a positive FrameOffset (which is actually just the CFA value for the frame).
