misc/ios: add support for running programs on the iOS simulator

2020-10-03T17:02:58+00:00

Update the README to mention the emulator. Remove reference to gomobile
while here; there are multiple ways to develop for iOS today, including
using the c-archive buildmode directly.

all: remove scattered remnants of darwin/arm

2020-04-08T18:35:49+00:00

This removes all conditions and conditional code (that I could find)
that depended on darwin/arm.

Fixes #35439 (since that only happened on darwin/arm)
Fixes #37611.

runtime/cgo: declare variable setg_gcc as static

2019-04-18T00:06:12+00:00

variable setg_gcc in runtime/cgo/*.c should be static, otherwise it
will be mixed with the function of the same name in runtime/asm_*.s or
tls_*.s, which causes an error when building PIE with internal linking
mode.

misc/ios,runtime/cgo: remove SIGINT handshake for the iOS exec wrapper

2018-04-10T16:30:07+00:00

Once upon a time, the iOS exec wrapper needed to change the current
working directory for the binary being tested. To allow that, the
runtime raised a SIGINT signal that the wrapper caught, changed the
working directory and resumed the process.

These days, the current working directory is passed from the wrapper
to the runtime through a special entry in the app metadata and the
SIGINT handshake is not necessary anymore.

Remove the signaling from the runtime and the exec harness.

runtime/cgo: make sure nil is undefined before defining it

2018-03-07T21:08:19+00:00

While working on standalone builds of gomobile bindings, I ran into
errors on the form:

gcc_darwin_arm.c:30:31: error: ambiguous expansion of macro 'nil' [-Werror,-Wambiguous-macro]
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS11.2.sdk/usr/include/MacTypes.h:94:15: note: expanding this definition of 'nil'

Fix it by undefining nil before defining it in libcgo.h.

misc/ios,cmd/go, runtime/cgo: fix iOS test harness (again)

2017-03-04T01:43:13+00:00

The iOS test harness was recently changed in response to lldb bugs
to replace breakpoints with the SIGUSR2 signal (CL 34926), and to
pass the current directory in the test binary arguments (CL 35152).
Both the signal sending and working directory setup is done from
the go test driver.

However, the new method doesn't work with tests where a C program is
the test driver instead of go test: the current working directory
will not be changed and SIGUSR2 is not raised.

Instead of copying that logic into any C test program, rework the
test harness (again) to move the setup logic to the early runtime
cgo setup code. That way, the harness will run even in the library
build modes.

Then, use the app Info.plist file to pass the working
directory, removing the need to alter the arguments after running.

Finally, use the SIGINT signal instead of SIGUSR2 to avoid
manipulating the signal masks or handlers.

Fixes the testcarchive tests on iOS.

With this CL, both darwin/arm and darwin/arm64 passes all.bash.

This CL replaces CL 34926, CL 35152 as well as the fixup CL
35123 and CL 35255. They are reverted in CLs earlier in the
relation chain.
