+/* This file contains dummy references to libgcc.a functions to force the
+ * dynamic linker to copy their definition into the final libc.so binary.
+ *
+ * They are required to ensure backwards binary compatibility with
+ * Android 1.5 and Android 1.6 system images. Some applications built
+ * using the NDK require them to be here.
+ *
+ * Now, for a more elaborate description of the issue:
+ *
+ * libgcc.a is a compiler-specific library containing various helper
+ * functions used to implement certain operations that are not necessarily
+ * supported by the target CPU. For example, integer division doesn't have a
+ * corresponding CPU instruction on ARMv5, and is instead implemented in the
+ * compiler-generated machine code as a call to an __idiv helper function.
+ *
+ * Normally, one has to place libgcc.a in the link command used to generate
+ * target binaries (shared libraries and executables) after all objects and
+ * static libraries, but before dependent shared libraries, i.e. something
+ * like:
+ *         gcc <options> -o libfoo.so  foo.a libgcc.a -lc -lm
+ *
+ * This ensures that any helper function needed by the code in foo.a is copied
+ * into the final libfoo.so. Unfortunately, the Android build system has been
+ * using this instead:
+ *
+ *         gcc <options> -o libfoo.so foo.a -lc -lm libgcc.a
+ *
+ * The problem with this is that if one helper function needed by foo.a has
+ * already been copied into libc.so or libm.so, then nothing will be copied
+ * into libfoo.so. Instead, a symbol import definition will be added to it
+ * so libfoo.so can directly call the one in libc.so at runtime.
+ *
+ * When changing toolchains for 2.0, the set of helper functions copied to
+ * libc.so changed, which resulted in some native shared libraries generated
+ * with the NDK to fail to load properly.
+ *
+ * The NDK has been fixed after 1.6_r1 to use the correct link command, so
+ * any native shared library generated with it should now be safe from that
+ * problem. On the other hand, existing shared libraries distributed with
+ * applications that were generated with a previous version of the NDK
+ * still need all 1.5/1.6 helper functions in libc.so and libn.so
+ *
+ * Final note: some of the functions below should really be in libm.so to
+ *             completely reflect the state of 1.5/1.6 system images. However,
+ *             since libm.so depends on libc.so, it's easier to put all of
+ *             these in libc.so instead, since the dynamic linker will always
+ *             search in libc.so before libm.so for dependencies.
