2012-01-25Delete the driver's HostInfo class. This abstraction just never reallyChandler Carruth
did anything. The two big pieces of functionality it tried to provide was to cache the ToolChain objects for each target, and to figure out the exact target based on the flag set coming in to an invocation. However, it had a lot of flaws even with those goals: - Neither of these have anything to do with the host, or its info. - The HostInfo class was setup as a full blown class *hierarchy* with a separate implementation for each "host" OS. This required dispatching just to create the objects in the first place. - The hierarchy claimed to represent the host, when in fact it was based on the target OS. - Each leaf in the hierarchy was responsible for implementing the flag processing and caching, resulting in a *lot* of copy-paste code and quite a few bugs. - The caching was consistently done based on architecture alone, even though *any* aspect of the targeted triple might change the behavior of the configured toolchain. - Flag processing was already being done in the Driver proper, separating the flag handling even more than it already is. Instead of this, we can simply have the dispatch logic in the Driver which previously created a HostInfo object create the ToolChain objects. Adding caching in the Driver layer is a tiny amount of code. Finally, pulling the flag processing into the Driver puts it where it belongs and consolidates it in one location. The result is that two functions, and maybe 100 lines of new code replace over 10 classes and 800 lines of code. Woot. This also paves the way to introduce more detailed ToolChain objects for various OSes without threading through a new HostInfo type as well, and the accompanying boiler plate. That, of course, was the yak I started to shave that began this entire refactoring escapade. Wheee! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148950 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-25Switch the ToolChain types to all store a Driver reference rather thanChandler Carruth
a HostInfo reference. Nothing about the HostInfo was used by any toolchain except digging out the driver from it. This just makes that a lot more direct. The change was accomplished entirely mechanically. It's one step closer to removing the shim full of buggy copy/paste code that is HostInfo. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148945 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-24Remove HostInfo::useDriverDriver(). This was only used in two placesChandler Carruth
inside the innards of the Driver implementation, and only ever implemented to return 'true' for the Darwin OSes. Instead use a more direct query on the target triple and a comment to document why the target matters here. If anyone is worried about this predicate getting wider use or improper use, I can make it a local or private predicate in the driver. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148797 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-16Make the triple an explicit argument of FindTargetProgramPath.Joerg Sonnenberger
Preserve the original triple in the NetBSD toolchain when using -m32 or -m64 and the resulting effective target is different from the triple it started with. This allows -m32 to use the same assembler/linking in cross-compiling mode and avoids confusion about passing down target specific flags in that case like --32. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131404 91177308-0d34-0410-b5e6-96231b3b80d8
