* Remove now unused arguments from TargetRegistry::lookupTarget.Daniel Dunbar2009-08-031-14/+11
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77950 91177308-0d34-0410-b5e6-96231b3b80d8
* Pass target triple string in to TargetMachine constructor.Daniel Dunbar2009-08-031-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is not just a matter of passing in the target triple from the module; currently backends are making decisions based on the build and host architecture. The goal is to migrate to making these decisions based off of the triple (in conjunction with the feature string). Thus most clients pass in the target triple, or the host triple if that is empty. This has one important change in the way behavior of the JIT and llc. For the JIT, it was previously selecting the Target based on the host (naturally), but it was setting the target machine features based on the triple from the module. Now it is setting the target machine features based on the triple of the host. For LLC, -march was previously only used to select the target, the target machine features were initialized from the module's triple (which may have been empty). Now the target triple is taken from the module, or the host's triple is used if that is empty. Then the triple is adjusted to match -march. The take away is that -march for llc is now used in conjunction with the host triple to initialize the subtarget. If users want more deterministic behavior from llc, they should use -mtriple, or set the triple in the input module. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77946 91177308-0d34-0410-b5e6-96231b3b80d8

* Twines: Support numeric conversion directly (uitostr, etc).Daniel Dunbar2009-07-291-11/+37
| | | | | | | | | | | | | | | | - Provides static constructors for doing number to string conversions without using temporaries. - There are several ways to do this, I think given the Twine constraints this is the simplest one. - One FIXME for fast number -> hex conversion. - Added another comment on one last major bit of perf work Twines need, which is to make raw_svector_ostream more efficient. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77445 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | - This is a simplified mechanism which just looks up a target based on the target triple, with a few additional flags. - Remove getClosestStaticTargetForModule, the moral equivalent is now: lookupTarget(Mod->getTargetTriple, true, false, ...); - This no longer does the fuzzy matching with target data (based on endianness and pointer width) that getClosestStaticTargetForModule was doing, but this was deemed unnecessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77111 91177308-0d34-0410-b5e6-96231b3b80d8

* Change raw_ostream so that it doesn't call llvm_report_errorDan Gohman2009-07-151-4/+14
| | | | | | | | | | | | | | | | | | | immediately on every output error. Instead, add a flag to raw_ostream, and set the flag whenever an error is detected. The flag can be queried and cleared from the public API. This gives applications more flexibility to handling errors in application-specific ways. If the flag is not cleared when the raw_ostream is destructed, llvm_report_error is called from the destructor. This ensures that errors are not implicitly silenced, and provides convenient default behavior for tools like llc and opt. Clients wishing to avoid llvm_report_error calls from raw_ostream should check for errors and clear the error flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75857 91177308-0d34-0410-b5e6-96231b3b80d8
