Merge branch 'bjorn/line-numbers-in-exceptions/OTP-9468' into major
* bjorn/line-numbers-in-exceptions/OTP-9468: (51 commits) debugger: By default, only save non-tail-recursive calls debugger: Add line_number_SUITE debugger: Include line numbers in exceptions Update examples in the documentation to include line numbers Update documentation for erlang:raise/3 and erlang:get_stacktrace/0 beam_lib: Retain the "Line" chunk when stripping BEAM files erl: Add +L to suppress loading of line number information compiler: Add no_line_info for suppressing line/1 instructions exception_SUITE: Test line numbers in exceptions common_test: Use line numbers in exceptions common_test tests: Don't do detailed testing of the stack backtrace test_server: Refactor init_per_testcase/3 into two functions Implement process_info(Pid, current_{location,stacktrace}) beam_emu: Factor out saving of stack trace from save_stacktrace() compiler: Don't create filenames starting with "./" ops.tab: Remove line instructions before tail-recursive calls Lookup and include filenames and line numbers in exceptions Fix decrement of continuation pointers Refactor building of the exception stacktrace BEAM loader: Load the line table ...
