Go1.11 uses the is_stmt flag of .debug_line to communicate which assembly instructions are good places for breakpoints, we should respect this flag. These changes were introduced by: * https://go-review.googlesource.com/c/go/+/102435/ Additionally when setting next breakpoints ignore all PC addresses that belong to the same line as the one currently under at the cursor. This matches the behavior of gdb and avoids stopping multiple times at the heading line of a for statement with go1.11. Change: https://go-review.googlesource.com/c/go/+/110416 adds the prologue_end flag to the .debug_line section to communicate the end of the stack-split prologue. We should use it instead of pattern matching the disassembly when available. Fixes #550 type of interfaces 'c7cde8b'.

dlv trace
Compile and begin tracing program.
Synopsis
Trace program execution.
The trace sub command will set a tracepoint on every function matching the provided regular expression and output information when tracepoint is hit. This is useful if you do not want to begin an entire debug session, but merely want to know what functions your process is executing.
dlv trace [package] regexp
Options
--output string Output path for the binary. (default "debug")
-p, --pid int Pid to attach to.
-s, --stack int Show stack trace with given depth.
Options inherited from parent commands
--accept-multiclient Allows a headless server to accept multiple client connections. Note that the server API is not reentrant and clients will have to coordinate.
--api-version int Selects API version when headless. (default 1)
--backend string Backend selection:
default Uses lldb on macOS, native everywhere else.
native Native backend.
lldb Uses lldb-server or debugserver.
rr Uses mozilla rr (https://github.com/mozilla/rr).
(default "default")
--build-flags string Build flags, to be passed to the compiler.
--headless Run debug server only, in headless mode.
--init string Init file, executed by the terminal client.
-l, --listen string Debugging server listen address. (default "localhost:0")
--log Enable debugging server logging.
--log-output string Comma separated list of components that should produce debug output, possible values:
debugger Log debugger commands
gdbwire Log connection to gdbserial backend
lldbout Copy output from debugserver/lldb to standard output
debuglineerr Log recoverable errors reading .debug_line
Defaults to "debugger" when logging is enabled with --log.
--wd string Working directory for running the program. (default ".")
