Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      It's not Google's fault. ARM defined the EABI stack unwinder strangely. Android didn't support exceptions at first.https://twitter.com/RichFelker/status/711009996419559425 …

      @jhamby @jserv Huh? This must be something bogus about how Google built the toolchain. GCC has not used "SJLJ" since, like, ages ago.

      @jhamby I know ARM has their own wacky thing instead of using normal dwarf tables, but GCC supported it since way back.

      @jhamby If Google used SJLJ for Android it's because they were overriding the GCC defaults and doing something dumb.

          .@RichFelker Google didn't use SJLJ for Android. I misread the headers. Google didn't support C++ exceptions in the NDK API until later.

          .@RichFelker The worst C++ ABI for ARM was Symbian. They used an ancient version of GCC, rolled their own SJLJ-style exceptions with macros.

          .@RichFelker My basic complaint with Android is it's "the revenge of BeOS". They forced Java on developers, just like BeOS forced C++ APIs.

          .@RichFelker Two basic complaints with BeOS in 1997: 1) the fragile base class problem, which they solved by padding public C++ classes.

          .@RichFelker 2) BeOS forced developers to use threads, which led to tons of race conditions. Each BWindow needed its own event loop thread.

          .@RichFelker So my impression of Android is: ex-Be devs (Travis Geiselbrecht, Dianne Hackborn, et al) rewrote BeOS in Java instead of C++.

          .@RichFelker The major architectural difference was to use a single UI event thread, just like every other GUI API that became successful.

          .@RichFelker My major complaint with Android is that all apps are forced to run the Java VM in user space to interface with the system.
