Informationen

GenCodeHook.pas (CodeLen.pas, CodeMem.pas, CodeMemOpt.pas)

Delphi unit containing functions to do a generic code hook by replacing the
code location to be patched by a jump to the new location. Additionally, a
new code fragment is created that allows to call the old function. See the
included README.txt for more information and how to use it.

Änderungen

2005-10-23: Version 1.4

Almost complete rewrite of CodeLen.pas with the new functions "AnalyzeCpuInstructionSequence", "LengthOfCpuInstructionSequence", and "CopyCpuInstructionSequence".
Modified "CreateGenericCodeHook" to use two different branch types instead of a pc-relative displacement.
Removed the flag "Is16Bit" - did never work for 16-bit code.
Still no support for Windows 95/98/Me system area ($80000000-$FFFFFFFF).

Version 1.3 (non-public)

Removed from WebSite because of several problems regarding relocation of relative displacements, and with Windows 9x/Me and global hooks.
Added "AnalyzeCpuInstruction" for a thorough analysis of the instruction, including referenced code and data memory.

2005-09-16: Version 1.2

First public version (added sample application).
Enhanced "PatchMemory" by first overwriting the first byte with $CC.
Added some AMD specific instructions and 3DNow to "CodeLen.pas".

2005-09-15: Version 1.1

Added module "CodeMem.pas" for extensible code memory allocation.
Wrote optimized code memory manager "CodeMemOpt.pas".
Enhanced "PatchMemory" by "FlushInstructionCache".
Added function "IsJumpInstruction" to "CodeLen.pas".

2005-09-15: Version 1.0

Initial version, derived from the "PrintToFile" project.
