| | | | | | | | | | | | having a library both as bitcode and native code. We want to use the bitcode first, but if codegen produces new undefined references we have to use the native code to satisfy those references. Gold has no notion of bitcode and native search directories, so instead it has an API where the plugin can instruct it to look for the libraries it is passing to it. This patch uses that API. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106674 91177308-0d34-0410-b5e6-96231b3b80d8

* Make LLVM command-line tools overwrite their output files without -f.Dan Gohman2009-08-25
| | | | | | | | | | | | | | | | | 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. Update Makefiles and documentation accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79990 91177308-0d34-0410-b5e6-96231b3b80d8
