* Make changes to rev 84292 as requested by Chris Lattner.Victor Hernandez2009-10-211-7/+4
| | | | | | | | Most changes are cleanup, but there is 1 correctness fix: I fixed InstCombine so that the icmp is removed only if the malloc call is removed (which requires explicit removal because the Worklist won't DCE any calls since they can have side-effects). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84772 91177308-0d34-0410-b5e6-96231b3b80d8

* Include optional subclass flags, such as inbounds, nsw, etc., in theDan Gohman2009-09-041-22/+34
| | | | | | | | | | | | | | | | | | Constant uniquing tables. This allows distinct ConstantExpr objects with the same operation and different flags. Even though a ConstantExpr "a + b" is either always overflowing or never overflowing (due to being a ConstantExpr), it's still necessary to be able to represent it both with and without overflow flags at the same time within the IR, because the safety of the flag may depend on the context of the use. If the constant really does overflow, it wouldn't ever be safe to use with the flag set, however the use may be in code that is never actually executed. This also makes it possible to merge all the flags tests into a single test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80998 91177308-0d34-0410-b5e6-96231b3b80d8

* Make LLVM command-line tools overwrite their output files without -f.Dan Gohman2009-08-251-1/+1
| | | | | | | | | | | | | | | | | This is conventional command-line tool behavior. -f now just means "enable binary output on terminals". Add a -f option to llvm-extract and llvm-link, for consistency. Remove F_Force from raw_fd_ostream and enable overwriting and truncating by default. Introduce an F_Excl flag to permit users to enable a failure when the file already exists. This flag is currently unused.
