* Stop building RTTI information for *most* llvm libraries. NotableChris Lattner2010-01-221-0/+1
| | | | | | | | | | | | | missing ones are libsupport, libsystem and libvmcore. libvmcore is currently blocked on bugpoint, which uses EH. Once it stops using EH, we can switch it off. This #if 0's out 3 unit tests, because gtest requires RTTI information. Suggestions welcome on how to fix this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94164 91177308-0d34-0410-b5e6-96231b3b80d8

* Include config.h in order to have HAVE_STDINT_H be defined.Duncan Sands2009-10-221-0/+1
| | | | | | | | In the latest binutils the plugin-api.h needs this - without it the LLVM gold plugin fails to compile. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84861 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix Makefile to build correctly on Darwin. Patch by Sandeep Patel!Nick Lewycky2009-10-111-2/+3

* 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. Update Makefiles and documentation accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79990 91177308-0d34-0410-b5e6-96231b3b80d8
* Change raw_fd_ostream to take flags as an optional bitmask Chris Lattner2009-08-231-4/+3
| | | | | | | | | | | | | | | | | | | 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
* Add a Force option to raw_fd_ostream to specify whether openingDan Gohman2009-07-151-1/+3
| | | | | | | | | an existing file is considered an error. Convert several tools to use raw_fd_ostream instead of std::ostream, and to use this new option instead of doing a manual check. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75801 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove the gcc= option. llvm-gcc uses only as=Rafael Espindola2009-06-151-12/+5
| | | | | | | | | | Look for as in the path. Doing it here instead of llvm-gcc because llvm-gcc has nothing as convenient as sys::Program::FindProgramByName. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73383 91177308-0d34-0410-b5e6-96231b3b80d8
