From ba4537805da7023ae48cef0cdc06e6724156c596 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 13 Jun 2016 11:57:18 +0100 Subject: linux-user: Create a hostdep.h for each host architecture In commit 4d330cee37a21 a new hostdep.h file was added, with the intent that host architectures which needed one could provide it, and the build system would automatically fall back to a generic version if there was no version for the host architecture. Although this works, it has a flaw: if a subsequent commit switches an architecture from "uses generic/hostdep.h" to "uses its own hostdep.h" nothing in the makefile dependencies notices this and so doing a rebuild without a manual 'make clean' will fail. So we drop the idea of having a 'generic' version in favour of every architecture we support having its own hostdep.h, even if it doesn't have anything in it. (There are only thirteen of these.) If the dependency files claim that an object file depends on a nonexistent file, our dependency system means that make will rebuild the object file, and regenerate the dependencies in the process. So moving between trees prior to this commit and trees after this commit works without requiring a 'make clean'.
