* Change raw_fd_ostream to take flags as an optional bitmask Chris Lattner2009-08-23
| | | | | | | | | | | | | | | | | | | instead of as two bools. Use this to add a F_Append flag which has the obvious behavior. Other unrelated changes conflated into this patch: 1. REmove EH stuff from llvm-dis and llvm-as, the try blocks are dead. 2. Simplify the filename inference code in llvm-as/llvm-dis, because raw_fd_ostream does the right thing with '-'. 3. Switch machine verifier to use raw_ostream instead of ostream (Which is the thing that needed append in the first place). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79807 91177308-0d34-0410-b5e6-96231b3b80d8

* The attached patches attempt to fix cross builds. For example, if youAnton Korobeynikov2009-08-18
| | | | | | | | | | | | | try to use i686-darwin to build for arm-eabi, you'll quickly run into several false assumptions that the target OS must be the same as the host OS. These patches split $(OS) into $(HOST_OS) and $(TARGET_OS) to help builds like "make check" and the test-suite able to cross compile. Along the way a target of *-unknown-eabi is defined as "Freestanding" so that TARGET_OS checks have something to work with.
