c5af65fe5f Fix passing arg9 (qvm only), arg10, and arg11 to vmMain for native libs and non-i386 compiled or interpated qvms. (Currently they aren't use in vmMain in game, cgame, or ui.) 
Fix passing args[11] to args[15] from vm to engine on ppc64 and sparc64. Some of the args are used by game bot prediction syscalls. May have been causing bugs. Note: This was fixed for x86_64 in r2163.

ffac0e6757 Move argument passing from VM to engine to global variables which allows to get rid of lots of OS specific stuff and also fixes errors that happens when compilers add lots of boilerplate to the DoSyscall() function 2012-08-08 09:34:03 +00:00

03201aff22 - Add MASM assembler files for MSVC x64 projects to support vm_x86 in x64 mode 
- Clean up ftol()/snapvector() mess
- Make use of SSE instructions for ftol()/snapvector() if available
- move ftol/snapvector pure assembler to inline assembler, this will add x86_64 and improve support for different calling conventions
- Set FPU control word at program startup to get consistent behaviour on all platforms

71b8fe477d - Use EmitCallDoSyscall() to call the jump violations function which guarantees 16-byte stack alignment 
- Add x64 code for MSVC _asm() blocks, not tested yet.

4b1418c4ad - Implement opStack protection: Use register %ebx for scaled indexed addressing mode to access opStack, make opStack push/pop operate on %bl portion only 
- Add a third pass to VM compilation for computation of jump address offsets, removing the need to dereference into vm->instructionPointers[] for every call/jump
- Make use of 0F opcode prefix relative jumps
- Call Com_Memcpy for OP_BLOCK_COPY
- Fix several missing range checks for vm->dataBase memory access

4c242115dc - change long to intptr_t for 64bit windows compatability 
- change vmMain arguments back to int. 64bit types are apparently not
  needed there. Only the syscall function needs them.

ffdc69f138 * Deleted code/unix/vm_x86.c - wtf was that about anyway? 
* Removed HAVE_VM_NATIVE
* Removed DLL_ONLY
* Replace HAVE_VM_COMPILED with NO_VM_COMPILED -- this means the JIT compiler
  should be enabled on the OS X and VC builds now
* Remove the remainder of the freetype building stuff

d5fbff3f44 revert int->long change as it breaks on 64bit. Actually only 
VM_CallInterpreted hurts as VM_CallCompiled is only used on 32bit. Use
same arg types for consistency nevertheless.
