23	/** @page pg_vboxrem_amd64 VBoxREM Hacks on AMD64
24	*
25	* There are problems with building BoxREM both on WIN64 and 64-bit linux.
26	*
27	* On linux binutils refuses to link shared objects without -fPIC compiled code
28	* (bitches about some fixup types). But when trying to build with -fPIC dyngen
29	* doesn't like the code anymore. Sweet. The current solution is to build the
30	* VBoxREM code as a relocatable module and use our ELF loader to load it.
31	*
32	* On WIN64 we're not aware of any GCC port which can emit code using the MSC
33	* calling convention. So, we're in for some real fun here. The choice is between
34	* porting GCC to AMD64 WIN64 and comming up with some kind of wrapper around
35	* either the win32 build or the 64-bit linux build.
36	*
37	* -# Porting GCC will be a lot of work. For one thing the calling convention differs
38	* and messing with such stuff can easily create ugly bugs. We would also have to
39	* do some binutils changes, but I think those are rather small compared to GCC.
40	* (That said, the MSC calling convention is far simpler than the linux one, it
41	* reminds me of _Optlink which we have working already.)
42	* -# Wrapping win32 code will work, but addresses outside the first 4GB are
43	* inaccessible and we will have to create 32-64 thunks for all imported functions.
44	* (To switch between 32-bit and 64-bit is load the right CS using far jmps (32->64)
45	* or far returns (both).)
46	* -# Wrapping 64-bit linux code might be the easier solution. The requirements here
47	* are:
48	* - Remove all CRT references we possibly, either by using intrinsics or using
49	* IPRT. Part of IPRT will be linked into VBoxREM2.rel, this will be yet another
50	* IPRT mode which I've dubbed 'no-crt'. The no-crt mode provide basic non-system
51	* dependent stuff.
52	* - Compile and link it into a relocatable object (include the gcc intrinsics
53	* in libgcc). Call this VBoxREM2.rel.
54	* - Write a wrapper dll, VBoxREM.dll, for which during REMR3Init() will load
55	* VBoxREM2.rel (using IPRT) and generate calling convention wrappers
56	* for all IPRT functions and VBoxVMM functions that it uses. All exports
57	* will be wrapped vice versa.
58	* - For building on windows hosts, we will use a mingw32 hosted cross compiler.
59	* and add a 'no-crt' mode to IPRT where it provides the necessary CRT headers
60	* and function implementations.
61	*
62	* The 3rd solution will be tried out first since it requires the least effort and
63	* will let us make use of the full 64-bit register set.
64	*
65	*
66	*
67	* @section sec_vboxrem_amd64_compare Comparing the GCC and MSC calling conventions
68	*
69	* GCC expects the following (cut & past from page 20 in the ABI draft 0.96):
70	*
71	* @verbatim
72	%rax temporary register; with variable arguments passes information about the
73	number of SSE registers used; 1st return register.
74	[Not preserved]
75	%rbx callee-saved register; optionally used as base pointer.
76	[Preserved]
77	%rcx used to pass 4th integer argument to functions.
78	[Not preserved]
79	%rdx used to pass 3rd argument to functions; 2nd return register
80	[Not preserved]
81	%rsp stack pointer
82	[Preserved]
83	%rbp callee-saved register; optionally used as frame pointer

102	[Not preserved]
103	%xmm8-%xmm15 temporary registers
104	[Not preserved]
105	%mmx0-%mmx7 temporary registers
106	[Not preserved]
107	%st0 temporary register; used to return long double arguments
108	[Not preserved]
109	%st1 temporary registers; used to return long double arguments
110	[Not preserved]
111	%st2-%st7 temporary registers
112	[Not preserved]
113	%fs Reserved for system use (as thread specific data register)
114	[Not preserved]
115	@endverbatim
116	*
117	* Direction flag is preserved as cleared.
118	* The stack must be aligned on a 16-byte boundrary before the 'call/jmp' instruction.
119	*
120	*
121	*
122	* MSC expects the following:
123	* @verbatim
124	rax return value, not preserved.
125	rbx preserved.
126	rcx 1st argument, integer, not preserved.
127	rdx 2nd argument, integer, not preserved.
128	rbp preserved.
129	rsp preserved.
130	rsi preserved.
131	rdi preserved.
132	r8 3rd argument, integer, not preserved.
133	r9 4th argument, integer, not preserved.
134	r10 scratch register, not preserved.
135	r11 scratch register, not preserved.
136	r12-r15 preserved.
137	xmm0 1st argument, fp, return value, not preserved.
138	xmm1 2st argument, fp, not preserved.
139	xmm2 3st argument, fp, not preserved.
140	xmm3 4st argument, fp, not preserved.
141	xmm4-xmm5 scratch, not preserved.
142	xmm6-xmm15 preserved.
143	@endverbatim
144	*
145	* Dunno what the direction flag is...
146	* The stack must be aligned on a 16-byte boundrary before the 'call/jmp' instruction.
147	*
148	*
149	* Thus, When GCC code is calling MSC code we don't really have to preserve
150	* anything. But but MSC code is calling GCC code, we'll have to save esi and edi.
