2012-02-15First pass at Solaris toolchain support. This version compiles and links helloDavid Chisnall
world on Solaris 11 for both x86 and x86-64 using the built-in assembler and Solaris (not GNU) ld, however it currently relies on a hard-coded GCC location to find crtbegin.o and crtend.o, as well as libgcc and libgcc_eh. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150580 91177308-0d34-0410-b5e6-96231b3b80d8

(clang r149497 / llvm r149498) Also include the config.h header after all other headers, per the LLVM coding standards.

2012-01-31Revert r149083 which is not the direction we're going in the ClangChandler Carruth
driver based on discussions with Doug Gregor. There are several issues: 1) The patch was not reviewed prior to commit and there were review comments. 2) The design of the functionality (triple-prefixed tool invocation) isn't the design we want for Clang going forward: it focuses on the "user triple" rather than on the "toolchain triple", and forces that bit of state into the API of every single toolchain instead of handling it automatically in the common base classes. 3) The tests provided are not stable. They fail on a few Linux variants (Gentoo among them) and on mingw32 and some other environments. I *am* interested in the Clang driver being able to invoke triple-prefixed tools, but we need to design that feature the right way. This patch just extends the previous hack without fixing the underlying problems with it. I'm working on a new design for this that I will mail for review by tomorrow. I am aware that this removes functionality that NetBSD relies on, but this is ToT, not a release. This functionality hasn't been properly designed, implemented, and tested yet. We can't "regress" until we get something that really works, both with the immediate use cases and with long term maintenance of the Clang driver. For reference, the original commit log: Keep track of the original target the user specified before normalization. This used to be captured in DefaultTargetTriple and is used for the (optional) $triple-$tool lookup for cross-compilation. Do this properly by making it an attribute of the toolchain and use it in combination with the computed triple as index for the toolchain lookup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149337 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-25Remove the 'ToolTriple' concept from the NetBSD toolchain along with myChandler Carruth
gross hack to provide it from my previous patch removing HostInfo. This was enshrining (and hiding from my searches) the concept of storing and diff-ing the host and target triples. We don't have the host triple reliably available, so we need to merely inspect the target system. I've changed the logic in selecting library search paths for NetBSD to match what I provided for FreeBSD -- we include both search paths, but put the 32-bit-on-64-bit-host path first so it trumps. NetBSD maintainers, you may want to tweak this, or feel free to ask me to tweak it. I've left a FIXME here about the challeng I see in fixing this properly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148952 91177308-0d34-0410-b5e6-96231b3b80d8

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
2012-01-25Remove the TargetTriple object that I added to the Driver recently. ThisChandler Carruth
helped stage the refactoring of things a bit, but really isn't the right place for it. The driver may be responsible for compilations with many different targets. In those cases, having a target triple in the driver is actively misleading because for many of those compilations that is not actually the triple being targeted. This moves the last remaining users of the Driver's target triple to instead use the ToolChain's target triple. The toolchain has a single, concrete target it operates over, making this a more stable and natural home for it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148942 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-24Start hoisting the logic for computing the target triple into its ownChandler Carruth
function. The logic for this, and I want to emphasize that this is the logic for computing the *target* triple, is currently scattered throughout various different HostInfo classes ToolChain factoring functions. Best part, it is largely *duplicated* there. The goal is to hoist all of that up to here where we can deal with it once, and in a consistent manner. Unfortunately, this uncovers more fun problems: the ToolChains assume that the *actual* target triple is the one passed into them by these factory functions, while the *host* triple is the one in the driver. This already was a lie, and a damn lie, when the '-target' flag was specified. It only really worked when the difference stemmed from '-m32' and '-m64' flags. I'll have to fix that (and remove all the FIXMEs I've introduced here to document the problem) before I can finish hoisting the target-calculation logic. It's bugs all the way down today it seems... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148839 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
2012-01-24Hoist the targeted triple object into an actual object in the Driver.Chandler Carruth
The Driver has a fixed target, whether we like it or not, the DefaultTargetTriple is not a default. This at least makes things more honest. I'll eventually get rid of most (if not all) of DefaultTargetTriple with this proper triple object. Bit of a WIP. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148796 91177308-0d34-0410-b5e6-96231b3b80d8
