Zack Middleton 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.

Thilo Schulz 83522282f1 Various fixes to vm_interpreted.c: 
- Add opStack protection
- Fix dataMask check for OP_BLOCK_COPY
- Add instruction number check for conditional jumps
- Make errors in VM_PrepareInterpreter nonfatal

Thilo Schulz 9219cde4e8 - Small change to search path order - local files not in .pk3s take precedence over files in pk3s. Should make life easier for modders/mappers wanting to override textures that are already contained in some older pk3 
- Make VM loading more robust, change loading order: when vm_* == 0 first try loading DLL, then QVM in *each* search directory/path
- Fix FS_FileForHandle that would return a FILE pointer to invalid file handle 0

Thilo Schulz c174143dc2 - Add x86_64 support to vm_x86.c 
- Fix warning on mingw64

Thilo Schulz 61d6e6eb68 Use scaled indexing mode n=4 for addressing opStack, this way we can use the 8 bit offset value in %%bl to address an OPSTACK_SIZE of 1024 which was the old value. 2011-05-18 00:17:02 +00:00
Thilo Schulz c7a68bf283 - Set default opStack size to 256 
- Fix integer wraparound. opStack offset in rbx will always be >= 0
 2011-05-16 18:17:01 +00:00
Thilo Schulz 017bc7e5da - Add vm_x86.c optimization patch by Eugene C. 
- Remove ASM syntax specific code (AT&T vs MASM) for OP_CALL and replace with machine code

Ludwig Nussel 469c986640 more security checks in interpreter (#4249) 2009-11-01 19:58:07 +00:00
Ludwig Nussel cc9a74a218 Define stack sizes at central place 
also reverts bug 4282 as stack is included in bss already so nothing that needs fixing
 2009-11-01 19:58:03 +00:00
Ludwig Nussel 7a5243a3b2 use vm->callLevel to count recursive calls to VM_Call 
Throw an error if vm->callLevel is set and VM_Free is called.

Tim Angus 672cfbf16f * Merge unified-sdl to trunk 
* Bump Q3_VERSION to 1.35
 2007-09-05 18:17:46 +00:00
Ludwig Nussel 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.

Tim Angus 05e8ab9538 * Added STATUS 
* Updated TODO
* Moved ChangeLog to root
* Updated ChangeLog
* s/Foobar/Quake III Arena Source Code/
* Biggest patch EVAR. I wonder how many mail boxes this will fill...
 2005-10-29 01:53:09 +00:00
Tim Angus 3a2ad50406 * Moved various source files from their mod sdk locations to places more 
appropriate for open source Q3
* This patch looks bigger than it really is, however it will probably break the
  VC and OS X builds (easy to fix though)

Tim Angus 35cb35ff61 * (Non-trivial) fix to the "opStack corrupted in compiled code" bug 2005-10-13 14:47:00 +00:00
Ludwig Nussel 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.

Tim Angus cde9e9e93c * Fixed some long/int warnings, hopefully this doesn't disrupt the MSVC and/or 64bit builds 2005-09-26 16:13:14 +00:00
Ludwig Nussel 88171d6bb7 support for 64bit native mods 2005-08-30 20:30:17 +00:00
