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 function’s 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.
