amxmodx/amxmodx/amxexecn.asm
David Anderson b7c0c47c05 New "debug" status for amxx plugins. 
Correctly switches between amx_opcodelist and nodebug.
Fixed metamod and amxmodx GPL alignment.
Fixed debug mode not being set for non-JIT.

Raw Blame History

; AMXEXECN.ASM Abstract Machine for the "Small" language
;
;Some notes:
; * This file was adapted from AMXEXEC.ASM (for MASM/TASM/WASM). This
; version is for NASM (Netwide Assembler). NASM uses Intel syntax for
; the mnemonics, but it is not compatible with MASM.
; * The "calling convention" is __cdecl for the amx_exec_asm() itself and
; __cdecl or __stdcall for the native routines (the default is __cdecl,
; define the macro STDECL to set __stdcall).
; * The borland compiler uses different segment definitions as Microsoft
; Visual C/C++ and GNU GCC. To assemble the abstract machine with "Borland"
; segments, add the definition "BORLAND" on the command line.
; * You will need to compile the standard AMX.C file with the macro ASM32
; defined. On the command line, use:
; nasmw -f obj -d BORLAND amxexecn.asm
; bcc32 -DASM32 srun.c amx.c amxcore.c amxcons.c amxexecn.obj
; or
; nasmw -f win32 amxexecn.asm
; or
; nasm -f elf amxexecn.asm
; gcc -o srun -DLINUX -DASM32 -I../linux srun.c amx.c amxcore.c amxcons.c amxexecn.o
; * See the notes in AMXEXEC.ASM for more information and a change log).

;History (list of changes)
;-------------------------
; 6 march 2004 by Thiadmer Riemersma
; Corrected a bug in OP_FILL, where a cell preceding the array would
; be overwritten (zero'ed out). This bug was brought to my attention
; by Robert Daniels.
; 2 february 2004 by Thiadmer Riemersma (TR)
; Added checking of the return address in the RET and RETN opcodes.
; Changed handling of LINE opcode, so that the debugger can force a
; sleep.
; 22 december 2003 by Thiadmer Riemersma (TR)
; Added support for the SYMTAG and SYSCALL.D opcodes
; 3 october 2003 by Thiadmer Riemersma (TR)
; Added "non-debug" versions of various opcodes, to avoid repetitive
; checking of the "debug" flag.
; 15 September 2003 by Thiadmer Riemersma (TR)
; Minor corrections, mostly to support older versions of NASM
; 26 January 2003 by Thiadmer Riemersma (TR)
; Port to NASM
