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

e08299faf4 - Do assignment of value 0xDEADBEEF after the 4-byte alignment
- Add all GPR to clobber list as GCC function callAsmCall seems to change register r11 without saving it to stack first, which may result in SIGSEGV in VM_CallCompiled()

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

5aa3da2f84 - Fix SEGV in while loop getop() after t = b = 0
- Fix iss8, iss16 and iss32 which would not correctly detect 32-bit signed integer range
- Add support for "addb", "subb" etc. assembler mnemonic
- Change opStack protection for x86_64 VM: No overflow checks necessary anymore as offset register is 1 byte long only
