+ * and will be preserved by the function/method called according to APCS [ARM Procedure

+/* Under the Mac OS X PowerPC ABI, the first 8 integer and 13 floating point
+ * parameters are delivered in registers and are not on the stack, although
+ * stack space is allocated for them. The integer parameters are delivered
+ * in GPRs r3 through r10. The first 8 words of the parameter area on the

+ * the stack, but not in both. Although the first floating point parameters
+ * are passed in floating point registers, GPR space and stack space is
+ * reserved for them as well.
+ *
+ * SharedStub has passed pointers to the parameter section of the stack
+ * and saved copies of the GPRs and FPRs used for parameter passing. We
+ * don't care about the first parameter (which is delivered here as the self
+ * pointer), so SharedStub pointed us past that. argsGPR thus points to GPR
+ * r4 (corresponding to the first argument after the self pointer) and
+ * argsStack points to the parameter section of the caller's stack frame
+ * reserved for the same argument. This way, it is possible to reference
+ * either argsGPR or argsStack with the same index.
+ *
+ * Contrary to the assumption made by the previous implementation, the
+ * Mac OS X PowerPC ABI doesn't impose any special alignment restrictions on
+ * parameter sections of stacks. Values that are 64 bits wide appear on the

+
+ <h3>Overview</h3>
+
+ <blockquote>
+ <a href="http://www.mozilla.org/scriptable/xptcall-faq.html"> xptcall</a>
+ is a library that supports both invoking methods on arbitrary xpcom
+ objects and implementing classes whose objects can impersonate any xpcom
+ interface. It does this using platform specific assembly language code.
+ This code needs to be ported to all platforms that want to support xptcall
+ (and thus mozilla).
+ </blockquote>
+
+ <h3>The tree</h3>

+ </blockquote>
+
+ <h3>Theory of operation</h3>
+
+ <blockquote>
+ There are really two pieces of functionality: <i>invoke</i> and
+ <i>stubs</i>...
+
+ <p>
+ The <b><i>invoke</i></b> functionality requires the implementation of
+ the following on each platform (from
+ <a
+ href="http://lxr.mozilla.org/mozilla/source/xpcom/reflect/xptcall/xptcall.h"
+ >xptcall/xptcall.h</a
+ >):
+ </p>
+
+ <pre>
+XPTC_PUBLIC_API(nsresult)
+NS_InvokeByIndex(nsISupports* that, uint32_t methodIndex,
+ uint32_t paramCount, nsXPTCVariant* params);
+</pre
+ >
+
+ Calling code is expected to supply an array of
+ <code>nsXPTCVariant</code> structs. These are discriminated unions
+ describing the type and value of each parameter of the target function.
+ The platform specific code then builds a call frame and invokes the method
+ indicated by the index <code>methodIndex</code> on the xpcom interface
+ <code>that</code>.
+
+ <p>
+ Here are examples of this implementation for
+ <a
+ href="http://lxr.mozilla.org/mozilla/source/xpcom/reflect/xptcall/md/win32/xptcinvoke.cpp"
+ >Win32</a
+ >
+ and
+ <a
+ href="http://lxr.mozilla.org/mozilla/source/xpcom/reflect/xptcall/md/unix/xptcinvoke_unixish_x86.cpp"
+ >Linux x86, NetBSD x86, and FreeBSD</a
+ >. Both of these implementations use the basic strategy of: figure out
+ how much stack space is needed for the params, make the space in a new
+ frame, copy the params to that space, invoke the method, cleanup and
+ return. C++ is used where appropriate, Assembly language is used where
+ necessary. Inline assembly language is used here, but it is equally
+ valid to use separate assembly language source files. Porters can decide
+ how best to do this for their platforms.
+ </p>
+
+ <p>
+ The <b><i>stubs</i></b> functionality is more complex. The goal here is
+ a class whose vtbl can look like the vtbl of any arbitrary xpcom
+ interface. Objects of this class can then be built to impersonate any
+ xpcom object. The base interface for this is (from
+ <a
+ href="http://lxr.mozilla.org/mozilla/source/xpcom/reflect/xptcall/xptcall.h"
+ >xptcall/xptcall.h</a
+ >):
+ </p>
+
+ <pre>
+class nsXPTCStubBase : public nsISupports
+{
+public:
+ // Include generated vtbl stub declarations.
+ // These are virtual and *also* implemented by this class..
+#include "xptcstubsdecl.inc"
+
+ // The following methods must be provided by inheritor of this class.
+
+ // return a refcounted pointer to the InterfaceInfo for this object
+ // NOTE: on some platforms this MUST not fail or we crash!
+ NS_IMETHOD GetInterfaceInfo(const nsXPTInterfaceInfo** info) = 0;
+
+ // call this method and return result
+ NS_IMETHOD CallMethod(uint16_t methodIndex,
+ const nsXPTMethodInfo* info,
+ nsXPTCMiniVariant* params) = 0;
+};
+</pre
+ >
+
+ Code that wishes to make use of this <i>stubs</i> functionality (such as
+ <a href="http://www.mozilla.org/scriptable/">XPConnect</a>) implement a
+ class which inherits from <code>nsXPTCStubBase</code> and implements the
+ <code>GetInterfaceInfo</code> and <code>CallMethod</code> to let the
+ platform specific code know how to get interface information and how to
+ dispatch methods once their parameters have been pulled out of the
+ platform specific calling frame.
+
+ <p>
+ Porters of this functionality implement the platform specific code for
+ the
+ <i>stub</i> methods that fill the vtbl for this class. The idea here is
+ that the class has a vtbl full of a large number of generic stubs. All
+ instances of this class share that vtbl and the same stubs. The stubs
+ forward calls to a platform specific method that uses the interface
+ information supplied by the overridden <code>GetInterfaceInfo</code> to
+ extract the parameters and build an array of platform independent
+ <code>nsXPTCMiniVariant</code> structs which are in turn passed on to
+ the overridden <code>CallMethod</code>. The platform dependent code is
+ responsible for doing any cleanup and returning.
+ </p>
+
+ <p>
+ The stub methods are declared in
+ <a
+ href="http://lxr.mozilla.org/mozilla/source/xpcom/reflect/xptcall/xptcstubsdecl.inc"
+ >xptcall/xptcstubsdecl.inc</a
+ >. These are '#included' into the declaration of
+ <code>nsXPTCStubBase</code>. A similar include file (<a
+ href="http://lxr.mozilla.org/mozilla/source/xpcom/reflect/xptcall/xptcstubsdef.inc"
+ >xptcall/xptcstubsdef.inc</a
+ >) is expanded using platform specific macros to define the stub
+ functions. These '.inc' files are checked into cvs. However, they can be
+ regenerated as necessary (i.e. to change the number of stubs or to
+ change their specific declaration) using the Perl script
+ <a
+ href="http://lxr.mozilla.org/mozilla/source/xpcom/reflect/xptcall/genstubs.pl"
+ >xptcall/genstubs.pl</a
+ >.
+ </p>
+
+ <p>
+ Here are examples of this implementation for
+ <a
+ href="http://lxr.mozilla.org/mozilla/source/xpcom/reflect/xptcall/md/win32/xptcstubs.cpp"
+ >Win32</a
+ >
+ and
+ <a
+ href="http://lxr.mozilla.org/mozilla/source/xpcom/reflect/xptcall/md/unix/xptcstubs_unixish_x86.cpp"
+ >Linux x86, NetBSD x86, and FreeBSD</a
+ >. Both of these examples use inline assembly language. That is just how
+ I decided to do it. You can do it as you choose.
+ </p>
+
+ <p>
+ The Win32 version is somewhat tighter because the __declspec(naked)
+ feature allows for very small stubs. However, the __stdcall requires the
+ callee to clean up the stack, so it is imperative that the interface
+ information scheme allow the code to determine the correct stack pointer
+ fixup for return without fail, else the process will crash.
+ </p>
+
+ <p>
+ I opted to use inline assembler for the gcc Linux x86 port. I ended up
+ with larger stubs than I would have preferred rather than battle the
+ compiler over what would happen to the stack before my asm code began
+ running.
+ </p>
+
+ <p>
+ I believe that the non-assembly parts of these files can be copied and
+ reused with minimal (but not zero) platform specific tweaks. Feel free
+ to copy and paste as necessary. Please remember that safety and
+ reliability are more important than speed optimizations. This code is
+ primarily used to connect XPCOM components with JavaScript; function
+ call overhead is a <b>tiny</b> part of the time involved.
+ </p>
+
+ <p>
+ I put together
+ <a
+ href="http://lxr.mozilla.org/mozilla/source/xpcom/reflect/xptcall/md/test"
+ >xptcall/md/test
+ </a>
+ as a place to evolve the basic functionality as a port is coming
+ together. Not all of the functionality is exercised, but it is a place
+ to get started.
+ <a
+ href="http://lxr.mozilla.org/mozilla/source/xpcom/reflect/xptcall/tests"
+ >xptcall/tests
+ </a>
+ has an api level test for <code>NS_InvokeByIndex</code>, but no tests
+ for the <i>stubs</i> functionality. Such a test ought to be written, but
+ this has not yet been done.
+ </p>
+
+ <p>
+ A full 'test' at this point requires building the client and running the
+ XPConnect test called <i>TestXPC</i> in
+ <a href="http://lxr.mozilla.org/mozilla/source/js/xpconnect/tests"
+ >mozilla/js/xpconnect/tests </a
+ >.
