Hello, I'm interested in getting Valgrind working on PPC/Darwin. I see PPC and Darwin are already supported, so I see the last obstacle is "platform-specific code" for this combination of CPU and OS. What changes should be introduced into Valgrind sources to get it working? I'd like to try, but never worked with Valgrind sources. -- Regards, Konstantin |

Such a port would be unlikely to be incorporated into the Valgrind distribution because the maintenance effort wouldn't be worth the tiny audience for it. Nick |

It's a lot of work. To get some idea how much, grep the entire tree for #if defined(VGP_x86_darwin). You'd have to make an equivalent version for ppc32_darwin. There are a lot of such places, perhaps 100. J |

Not so many - only about 50 :) However, things are very complicated, and comments are not thorough enough for me to understand high-level logic Could you add some documentation about porting Valgrind to other platforms in future? -- Regards, Konstantin |
