* tests: misc test fixes for go1.14
- math.go is now ambiguous due to changes to the go runtime so specify
that we mean our own math.go in _fixtures
- go list -m requires vendor-mode to be disabled so pass '-mod=' to it
in case user has GOFLAGS=-mod=vendor
- update version of go/packages, required to work with go 1.14 (and
executed go mod vendor)
- Increased goroutine migration in one development version of Go 1.14
revealed a problem with TestCheckpoints in command_test.go and
rr_test.go. The tests were always wrong because Restart(checkpoint)
doesn't change the current thread but we can't assume that when the
checkpoint was taken the current goroutine was running on the same
thread.
* goversion: update maximum supported version
* Makefile: disable testing lldb-server backend on linux with Go 1.14
There seems to be some incompatibility with lldb-server version 6.0.0
on linux and Go 1.14.
* proc/gdbserial: better handling of signals
- if multiple signals are received simultaneously propagate all of them to the
target threads instead of only one.
- debugserver will drop an interrupt request if a target thread simultaneously
receives a signal, handle this situation.
* dwarf/line: normalize backslashes for windows executables
Starting with Go 1.14 the compiler sometimes emits backslashes as well
as forward slashes in debug_line, normalize everything to / for
conformity with the behavior of previous versions.
* proc/native: partial support for Windows async preempt mechanism
See https://github.com/golang/go/issues/36494 for a description of why
full support for 1.14 under windows is problematic.
* proc/native: disable Go 1.14 async preemption on Windows
See https://github.com/golang/go/issues/36494
* proc: separate amd64-arch code
separate amd64 code about stacktrace, so we can add arm64 stacktrace code.
* proc: implemente stacktrace of arm64
* delve now can use stack, frame commands on arm64-arch debug.

* test: remove skip-code of stacktrace on arm64
* add LR DWARF register and remove skip-code for fixed tests
* proc: fix the Continue command after the hardcoded breakpoint on arm64
Arm64 use hardware breakpoint, and it will not set PC to the next instruction like amd64. We should move PC in both runtime.breakpoints and hardcoded breakpoints(probably cgo).
* proc: implement cgo stacktrace on arm64
* proc: combine amd64_stack.go and arm64_stack.go file
* proc: reorganize the stacktrace code
* move SwitchStack function arch-related
* fix Continue command after manual stop on arm64
* add timeout flag to make.go to enable infinite timeouts

arm64 use hardware breakpoint, and it will not set PC to the next instruction like amd64. Let adjustPC always fasle in arm64, in case of infinite loop.
* proc/linux: do not route signals to threads while stopping
While we are trying to stop the process we should not route signals
sent to threads because that will result in threads being resumed.
Also keep better track of which threads are stopped.
This fixes an incompatibility with Go 1.14, which sends a lot of
signals to its threads to implement non-cooperative preemption,
resulting in Delve hanging waiting for an already-stopped thread to
stop.
In principle however this bug has nothing to do with Go 1.14 and could
manifest in any instance of high signal pressure.
* Makefile: discard stderr of "go list"
In module mode "go" will print messages about downloading modules to
stderr, we shouldn't confuse them for the real command output.
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.
Support for position independent executables (PIE) on the native linux
backend, the gdbserver backend on linux and the core backend.
Also implemented in the windows native backend, but it can't be tested
because go doesn't support PIE on windows yet.
On macOS 10.14 Apple changed the command line tools so that system
headers now need to be manually installed.
Instead of adding one extra install step to the install procedure add a
build tag to allow compilation of delve without the native backend on
macOS. By default (i.e. when using `go get`) this is how delve will be
compiled on macOS, the make script is changed to enable compiling the
native backend if the required dependencies have been installed.
Insure that both configuration still build correctly on Travis CI and
change the documentation to describe how to compile the native backend
and that it isn't normally needed.
Fixes#1359
We were using our makefile not for the intended purpose of makefiles
but to multiplex a series of small scripts.
We can easily achieve the same result in a more reasonable programming
language and as a bonus we don't need to install a version of make on
windows anymore.
Additionally our test script had become fairly complicated and will
become even more complicated when testing of PIE buildmode is
introduced.
Allows the tests to run on Windows without having to install Mingw
(although we still want it installed so that we can run cgo tests on
Windows).
Fixes building when GOPATH isn't set.
Fixes#759
