But when trying to build with -fPIC dyngen * doesn't like the code anymore. Sweet. The current solution is to build the * VBoxREM code as a relocatable module and use our ELF loader to load it. * * On WIN64 we're not aware of any GCC port which can emit code using the MSC * calling convention. So, we're in for some real fun here. The choice is between * porting GCC to AMD64 WIN64 and comming up with some kind of wrapper around * either the win32 build or the 64-bit linux build. * * -# Porting GCC will be a lot of work. For one thing the calling convention differs * and messing with such stuff can easily create ugly bugs. We would also have to * do some binutils changes, but I think those are rather small compared to GCC. * (That said, the MSC calling convention is far simpler than the linux one, it * reminds me of _Optlink which we have working already.) * -# Wrapping win32 code will work, but addresses outside the first 4GB are * inaccessible and we will have to create 32-64 thunks for all imported functions. * (To switch between 32-bit and 64-bit is load the right CS using far jmps (32->64) * or far returns (both).) * -# Wrapping 64-bit linux code might be the easier solution. The requirements here * are: * - Remove all CRT references we possibly, either by using intrinsics or using * IPRT. Part of IPRT will be linked into VBoxREM2.rel, this will be yet another * IPRT mode which I've dubbed 'no-crt'. The no-crt mode provide basic non-system * dependent stuff. * - Compile and link it into a relocatable object (include the gcc intrinsics * in libgcc). Call this VBoxREM2.rel. * - Write a wrapper dll, VBoxREM.dll, for which during REMR3Init() will load * VBoxREM2.rel (using IPRT) and generate calling convention wrappers * for all IPRT functions and VBoxVMM functions that it uses. All exports * will be wrapped vice versa. * - For building on windows hosts, we will use a mingw32 hosted cross compiler. * and add a 'no-crt' mode to IPRT where it provides the necessary CRT headers * and function implementations. * * The 3rd solution will be tried out first since it requires the least effort and * will let us make use of the full 64-bit register set. * * * * @section sec_vboxrem_amd64_compare Comparing the GCC and MSC calling conventions * * GCC expects the following (cut & past from page 20 in the ABI draft 0.96): * * %rax temporary register; with variable arguments passes information about the * number of SSE registers used; 1st return register. * [Not preserved] * %rbx callee-saved register; optionally used as base pointer. * [Preserved] * %rcx used to pass 4th integer argument to functions. * [Not preserved] * %rdx used to pass 3rd argument to functions; 2nd return register * [Not preserved] * %rsp stack pointer * [Preserved] * %rbp callee-saved register; optionally used as frame pointer * [Preserved] * %rsi used to pass 2nd argument to functions * [Not preserved] * %rdi used to pass 1st argument to functions * [Not preserved] * %r8 used to pass 5th argument to functions * [Not preserved] * %r9 used to pass 6th argument to functions * [Not preserved] * %r10 temporary register, used for passing a function’s static chain pointer * [Not preserved] * %r11 temporary register * [Not preserved] * %r12-r15 callee-saved registers * [Preserved] * %xmm0-%xmm1 used to pass and return floating point arguments * [Not preserved] * %xmm2-%xmm7 used to pass floating point arguments * [Not preserved] * %xmm8-%xmm15 temporary registers * [Not preserved] * %mmx0-%mmx7 temporary registers * [Not preserved] * %st0 temporary register; used to return long double arguments * [Not preserved] * %st1 temporary registers; used to return long double arguments * [Not preserved] * %st2-%st7 temporary registers * [Not preserved] * %fs Reserved for system use (as thread specific data register) * [Not preserved] * * Direction flag is preserved as cleared. * The stack must be aligned on a 16-byte boundrary before the 'call/jmp' instruction. * * * * MSC expects the following: * rax return value, not preserved. * rbx preserved. * rcx 1st argument, integer, not preserved. * rdx 2nd argument, integer, not preserved. * rbp preserved. * rsp preserved. * rsi preserved. * rdi preserved. * r8 3rd argument, integer, not preserved. * r9 4th argument, integer, not preserved. * r10 scratch register, not preserved. * r11 scratch register, not preserved. * r12-r15 preserved. * xmm0 1st argument, fp, return value, not preserved. * xmm1 2st argument, fp, not preserved. * xmm2 3st argument, fp, not preserved. * xmm3 4st argument, fp, not preserved. * xmm4-xmm5 scratch, not preserved. * xmm6-xmm15 preserved. * * Dunno what the direction flag is... * The stack must be aligned on a 16-byte boundrary before the 'call/jmp' instruction. * * * Thus, When GCC code is calling MSC code we don't really have to preserve * anything. But but MSC code is calling GCC code, we'll have to save esi and edi. * */ /******************************************************************************* * Defined Constants And Macros * *******************************************************************************/ /** @def USE_REM_STUBS * Define USE_REM_STUBS to stub the entire REM stuff.
