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	* %rax temporary register; with variable arguments passes information about the
72	* number of SSE registers used; 1st return register.
73	* [Not preserved]
74	* %rbx callee-saved register; optionally used as base pointer.
75	* [Preserved]
76	* %rcx used to pass 4th integer argument to functions.
77	* [Not preserved]
78	* %rdx used to pass 3rd argument to functions; 2nd return register
79	* [Not preserved]
80	* %rsp stack pointer
81	* [Preserved]
82	* %rbp callee-saved register; optionally used as frame pointer
83	* [Preserved]
84	* %rsi used to pass 2nd argument to functions
85	* [Not preserved]
86	* %rdi used to pass 1st argument to functions
87	* [Not preserved]
88	* %r8 used to pass 5th argument to functions
89	* [Not preserved]
90	* %r9 used to pass 6th argument to functions
91	* [Not preserved]
92	* %r10 temporary register, used for passing a functions static chain pointer
93	* [Not preserved]
94	* %r11 temporary register
95	* [Not preserved]
96	* %r12-r15 callee-saved registers
97	* [Preserved]
98	* %xmm0-%xmm1 used to pass and return floating point arguments
99	* [Not preserved]
100	* %xmm2-%xmm7 used to pass floating point arguments
101	* [Not preserved]
102	* %xmm8-%xmm15 temporary registers
103	* [Not preserved]
104	* %mmx0-%mmx7 temporary registers
105	* [Not preserved]
106	* %st0 temporary register; used to return long double arguments
107	* [Not preserved]
108	* %st1 temporary registers; used to return long double arguments
109	* [Not preserved]
110	* %st2-%st7 temporary registers
111	* [Not preserved]
112	* %fs Reserved for system use (as thread specific data register)
113	* [Not preserved]
114	*
115	* Direction flag is preserved as cleared.
116	* The stack must be aligned on a 16-byte boundrary before the 'call/jmp' instruction.
117	*
118	*
119	*
120	* MSC expects the following:
121	* rax return value, not preserved.
122	* rbx preserved.
123	* rcx 1st argument, integer, not preserved.
124	* rdx 2nd argument, integer, not preserved.
125	* rbp preserved.
126	* rsp preserved.
127	* rsi preserved.
128	* rdi preserved.
129	* r8 3rd argument, integer, not preserved.
130	* r9 4th argument, integer, not preserved.
131	* r10 scratch register, not preserved.
132	* r11 scratch register, not preserved.
133	* r12-r15 preserved.
134	* xmm0 1st argument, fp, return value, not preserved.
135	* xmm1 2st argument, fp, not preserved.
136	* xmm2 3st argument, fp, not preserved.
137	* xmm3 4st argument, fp, not preserved.
138	* xmm4-xmm5 scratch, not preserved.
139	* xmm6-xmm15 preserved.
140	*
141	* Dunno what the direction flag is...
142	* The stack must be aligned on a 16-byte boundrary before the 'call/jmp' instruction.
143	*
144	*
145	* Thus, When GCC code is calling MSC code we don't really have to preserve
146	* anything. But but MSC code is calling GCC code, we'll have to save esi and edi.
