This is to better allow configuration on various, unknown compilers.
Previously, we hardcoded how thread local storage was specified for a
few different compilers, but we were not following and C standard. In
C11, there is a standardized storage specifier _Thread_local for this
storage class, however this is now deprecated in various C++ compilers
for a new keyword, confusingly. Janet also does not claim to require the
C11 standard, so for maximum flexibilty, the storage specifier must be
specified at configure time.
In the cross compilation case, we need to resolve our
dependencies on libc twice, once for the build machine and once for the
target machine. This includes pthreads, -libc, and android-spawn.
Allows for builting with cosmopolitan, both with meson
and Makefile. Use:
CC=comsocc meson setup -Dipv6=false -Ddynamic_modules=false
-Dshared=false -Dos_name=cosmopolitan
to configure for cosmopolitan build.
By default, use more traditional linking pattern with meson.
The janet.exe will now link to janet-x.x.dll on windows (and
similar for linux/posix) when built with meson. This is slightly
less efficient and means that janet.exe built this way is no longer
standalone (you would need to move the dll along with the exe), but
plays better with most build systems.
This allows a configuration workflow that is a bit simpler than before
and doesn't requiring applying patches. Instead, add a config.mk to
source dir with JANETCONF_HEADER=myconfig.h and compile as usual.
The patching workflow will of course still work exactly as before.
Adds extra information to default information from supervisor
channels. For threaded channels as supervisors, we don't get
the source fiber so identifying the source of messages was not
possible. This change allows better multithreading with supervisors.
