Revision(s) 39739, 39749, 39860, 39862, 39865, 39869, 39871, 39903, 39905, 39917, 39956, 39959-39960, 39969, 39971, 39980, 39987, 40198-40201, 40472, 40532, 40535-40536 from trunk:
* Android: The list of supported syscalls has been auto-generated directly from android sources for each CPU.
* Minor adjustments to make all compilable with the proper list of Android syscalls.
........
* Re-generated lists of android syscalls by a new script. The lists are more correct now. The script's location: https://svn.freepascal.org/svn/fpcbuild/scripts/android
........
* Fixed UnhookSignal when RTL_SIGDEFAULT is passed. The bug have caused crash on aarch64-android due to out of bounds read of the rtlsig2ossig[] array.
........
+ Added support for the aarch64-android target.
........
* Set ICU data dir if it is not set by the system. It fixes issues on newer Android versions.
* Added more predefined ICU versions.
........
* android: Use the current dir as temp.
........
* Corrected TUContext record for aarch64-linux and aarch64-android. It fixes obtaining of an address of the instruction where a signal has thrown.
........
* Enabled safecall support for aarch64 to be on par with other cpus.
........
* Android: Reworked the startup code to use no assembly instructions. Generic assembler startup files contains only section data and are compiled for each CPU.
* Android: argc and argv are correct for shared libraries.
........
* Use syscall_nr_renameat for android.
........
+ added support for x86_64-android target.
........
+ Added the auto-generated list syscalls for mips64-android. It will be needed when mips64 is supported.
........
* x86_64-android requires sigreturn for proper signal handling.
........
* Register external gas assembler for aarch64-android and x86_64-android.
........
* Enabled compilation of the cpu unit for arm-android and x86_64-android.
........
* ucnv_open() must be called with some SSE exception masked on x86_64-android.
* Call u_init() during initialization.
........
* Create the ".note.gnu.build-id" section for android. It fixes debugging of shared libs in Android Studio.
........
* android: Removed cwstring from the uses clause of the unix unit. Use cwstring indirectly. It allows to avoid using cwstring if needed.
........
* ICU v3.8 on Android 1.5-2.1 is buggy and can't be unloaded properly.
........
* Fixed locale detection on new Android versions.
........
* Fixed obtaining a time zone information for 64-bit android.
........
* Since Android 8 the net.dnsX properties can't be read. Use Google Public DNS servers.
........
* android: Use libc for sockets since the "accept" syscall is blocked by SECCOMP, but the "accept4" alternative is not available on old Android versions (2.3 and older).
........
* android: Regenerated syscalls.
........
* android: Disabled usage of the "pselect6" and "ppoll" syscalls for arm-android. These syscalls are not available on old Android versions (2.3 or older).

The linker will always change BL to BLX if necessary, but not vice versa (linker version dependent).
"BLX label" ALWAYS changes the instruction set. It changes a processor in ARM state to Thumb state,
or a processor in Thumb state to ARM state.

Therefore if a shared library is loaded by JVM ( using dlopen() ),
it is not possible to use dlopen() in a units initialization code -
dlopen() simply hangs.
To workaround this issue, if a library exports JNI_OnLoad(), then
no unit initialization is performed during library load.
The initialization is called when JVM has loaded the library and calls
JNI_OnLoad().
git-svn-id: trunk@34406 -
* Cleanup of Android linker.
* Use only INSERT command in the linker script to inject custom .fpc sections. Whole linker script duplication is nor needed anymore.
* Use BFD linker, since GOLD linker does not support INSERT command. Other incompatibilities may also exist.
* Enable tf_smartlink_sections for i386-android.
* i386-android is broken after this commit. Will be fixed later.
