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 function’s 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.
