18	*
19	* There are problems with building BoxREM both on WIN64 and 64-bit linux.
20	*
21	* On linux binutils refuses to link shared objects without -fPIC compiled code
22	* (bitches about some fixup types). But when trying to build with -fPIC dyngen
23	* doesn't like the code anymore. Sweet. The current solution is to build the
24	* VBoxREM code as a relocatable module and use our ELF loader to load it.
25	*
26	* On WIN64 we're not aware of any GCC port which can emit code using the MSC
27	* calling convention. So, we're in for some real fun here. The choice is between
28	* porting GCC to AMD64 WIN64 and comming up with some kind of wrapper around
29	* either the win32 build or the 64-bit linux build.
30	*
31	* -# Porting GCC will be a lot of work. For one thing the calling convention differs
32	* and messing with such stuff can easily create ugly bugs. We would also have to
33	* do some binutils changes, but I think those are rather small compared to GCC.
34	* (That said, the MSC calling convention is far simpler than the linux one, it
35	* reminds me of _Optlink which we have working already.)
36	* -# Wrapping win32 code will work, but addresses outside the first 4GB are
37	* inaccessible and we will have to create 32-64 thunks for all imported functions.
38	* (To switch between 32-bit and 64-bit is load the right CS using far jmps (32->64)
39	* or far returns (both).)
40	* -# Wrapping 64-bit linux code might be the easier solution. The requirements here
41	* are:
42	* - Remove all CRT references we possibly, either by using intrinsics or using
43	* IPRT. Part of IPRT will be linked into VBoxREM2.rel, this will be yet another
44	* IPRT mode which I've dubbed 'no-crt'. The no-crt mode provide basic non-system
45	* dependent stuff.
46	* - Compile and link it into a relocatable object (include the gcc intrinsics
47	* in libgcc). Call this VBoxREM2.rel.
48	* - Write a wrapper dll, VBoxREM.dll, for which during REMR3Init() will load
49	* VBoxREM2.rel (using IPRT) and generate calling convention wrappers
50	* for all IPRT functions and VBoxVMM functions that it uses. All exports
51	* will be wrapped vice versa.
52	* - For building on windows hosts, we will use a mingw32 hosted cross compiler.
53	* and add a 'no-crt' mode to IPRT where it provides the necessary CRT headers
54	* and function implementations.
55	*
56	* The 3rd solution will be tried out first since it requires the least effort and
57	* will let us make use of the full 64-bit register set.
58	*
59	*
60	*
61	* @section sec_vboxrem_amd64_compare Comparing the GCC and MSC calling conventions
62	*
63	* GCC expects the following (cut & past from page 20 in the ABI draft 0.96):
64	*
65	* %rax temporary register; with variable arguments passes information about the
66	* number of SSE registers used; 1st return register.
67	* [Not preserved]
68	* %rbx callee-saved register; optionally used as base pointer.
69	* [Preserved]
70	* %rcx used to pass 4th integer argument to functions.
71	* [Not preserved]
72	* %rdx used to pass 3rd argument to functions; 2nd return register
73	* [Not preserved]
74	* %rsp stack pointer
75	* [Preserved]
76	* %rbp callee-saved register; optionally used as frame pointer
77	* [Preserved]
78	* %rsi used to pass 2nd argument to functions
79	* [Not preserved]
80	* %rdi used to pass 1st argument to functions
81	* [Not preserved]
82	* %r8 used to pass 5th argument to functions
83	* [Not preserved]
84	* %r9 used to pass 6th argument to functions
85	* [Not preserved]
86	* %r10 temporary register, used for passing a functions static chain pointer
87	* [Not preserved]
88	* %r11 temporary register
89	* [Not preserved]
90	* %r12-r15 callee-saved registers
91	* [Preserved]
92	* %xmm0%xmm1 used to pass and return floating point arguments
93	* [Not preserved]
94	* %xmm2%xmm7 used to pass floating point arguments
95	* [Not preserved]
96	* %xmm8%xmm15 temporary registers
97	* [Not preserved]
98	* %mmx0%mmx7 temporary registers
99	* [Not preserved]
100	* %st0 temporary register; used to return long double arguments
101	* [Not preserved]
102	* %st1 temporary registers; used to return long double arguments
103	* [Not preserved]
104	* %st2%st7 temporary registers
105	* [Not preserved]
106	* %fs Reserved for system use (as thread specific data register)
107	* [Not preserved]
108	*
109	* Direction flag is preserved as cleared.
110	* The stack must be aligned on a 16-byte boundrary before the 'call/jmp' instruction.
111	*
112	*
113	*
114	* MSC expects the following:
115	* rax return value, not preserved.
116	* rbx preserved.
117	* rcx 1st argument, integer, not preserved.
118	* rdx 2nd argument, integer, not preserved.
119	* rbp preserved.
120	* rsp preserved.
121	* rsi preserved.
122	* rdi preserved.
123	* r8 3rd argument, integer, not preserved.
124	* r9 4th argument, integer, not preserved.
125	* r10 scratch register, not preserved.
126	* r11 scratch register, not preserved.
127	* r12-r15 preserved.
128	* xmm0 1st argument, fp, return value, not preserved.
129	* xmm1 2st argument, fp, not preserved.
130	* xmm2 3st argument, fp, not preserved.
131	* xmm3 4st argument, fp, not preserved.
132	* xmm4-xmm5 scratch, not preserved.
133	* xmm6-xmm15 preserved.
134	*
135	* Dunno what the direction flag is...
136	* The stack must be aligned on a 16-byte boundrary before the 'call/jmp' instruction.
137	*
138	*
139	* Thus, When GCC code is calling MSC code we don't really have to preserve
140	* anything. But but MSC code is calling GCC code, we'll have to save esi and edi.
