Last change on this file since 55980 was 55980, checked in by vboxsync, 10 years ago

iprt/log.h,++: Added extended logger instance getters that also checks whether the given logger and group-flags are enabled, making the LogRel* checks more efficient in avoid uncessary RTLogLoggerEx parameter building and calls. Ditto for debug logging. The LOG_INSTANCE and LOG_REL_INSTANCE tricks are gone for now.

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