Date: Sat, 2 Feb 2008 22:08:05 +0100 From: Marcus von Appen To: sdl@lists.libsdl.org Subject: [SDL] [Patch] SDL-1.2 SDL_revcpy() asm patch for the cld flag Hi, as reported through the FreeBSD bug tracking system in SDL 1.2.13 (and in the 1.2 branch, if I see that correctly) the SDL_revcpy() macro sets the direction flag (std), but does not clear it afterwards (cld), which is wrong according to the GCC and SYS V specs. This can cause some weird side effects, which in turn can lead to memory corruption. You can read the full report with a detailed description and test program at http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/120052 Attached is the submitted patch, which fixes the issue.

==============================================================================
Using the Simple DirectMedia Layer with MacOS 7,8,9 on PPC
==============================================================================

These instructions are for people using the Apple MPW environment:
http://developer.apple.com/tools/mpw-tools/

CodeWarrior projects are available in the CWprojects directory.

==============================================================================
I.  Building the Simple DirectMedia Layer libraries:
    (This step isn't necessary if you have the SDL binary distribution)

  First, unpack the MPWmake.sea.hqx archive and move SDL.make into the
  SDL directory.

  Start MPW

  Set the current directory within MPW to the SDL toplevel directory.

  Build "SDL"  (Type Command-B and enter "SDL" in the dialog)

  If everything compiles successfully, you now have the PPC libraries
  "SDL" and "SDLmain.o" in the 'lib' subdirectory.

==============================================================================
II. Building the Simple DirectMedia Layer test programs:

  First, unpack the MPWmake.sea.hqx archive, move the new rsrc directory to
  the main SDL directory, and move the makefiles in the new test subdirectory
  to the SDL 'test' subdirectory.

  Start MPW

  Set the current directory within MPW to the SDL 'test' subdirectory.

  Build the programs that have an associated MPW makefile (file ending
  with .make), including "testwin", "testalpha", and "graywin".

  Copy the SDL library file into the test directory, and run!

==============================================================================
III. Building the Simple DirectMedia Layer demo programs:

  Copy one of the test program Makefiles to the demo directory
  and modify it to match the sources in the demo.

==============================================================================
IV.  Enjoy! :)

  If you have a project you'd like me to know about, or want to ask questions,
  go ahead and join the SDL developer's mailing list by sending e-mail to:

	sdl-request@libsdl.org

  and put "subscribe" into the subject of the message. Or alternatively you
  can use the web interface:
