* Fix some nasty callgraph dangling pointer problems in Chris Lattner2009-08-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | argpromotion and structretpromote. Basically, when replacing a function, they used the 'changeFunction' api which changes the entry in the function map (and steals/reuses the callgraph node). This has some interesting effects: first, the problem is that it doesn't update the "callee" edges in any callees of the function in the call graph. Second, this covers for a major problem in all the CGSCC pass stuff, which is that it is completely broken when functions are deleted if they *don't* reuse a CGN. (there is a cute little fixme about this though :). This patch changes the protocol that CGSCC passes must obey: now the CGSCC pass manager copies the SCC and preincrements its iterator to avoid passes invalidating it. This allows CGSCC passes to mutate the current SCC. However multiple passes may be run on that SCC, so if passes do this, they are now required to *update* the SCC to be current when they return. Other less interesting parts of this patch are that it makes passes update the CG more directly, eliminates changeFunction, and requires clients of replaceCallSite to specify the new callee CGN if they are changing it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80527 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | sections, etc. - The quick and dirty way, just clone the TargetLoweringObjectFile code. Eventually this should be shared... somehow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80168 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | - I moved section creation back into AsmParser. I think policy decisions like this should be pushed higher, not lower, when possible (in addition the assembler has flags which change this behavior, for example). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80162 91177308-0d34-0410-b5e6-96231b3b80d8

* Make LLVM command-line tools overwrite their output files without -f.Dan Gohman2009-08-2514-52/+31
| | | | | | | | | | | | | | | | | 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

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

* llvm-mc: Start MCAssembler and MCMachOStreamer.Daniel Dunbar2009-08-211-4/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Together these form the (Mach-O) back end of the assembler. - MCAssembler is the actual assembler backend, which is designed to have a reasonable API. This will eventually grow to support multiple object file implementations, but for now its Mach-O/i386 only. - MCMachOStreamer adapts the MCStreamer "actions" API to the MCAssembler API, e.g. converting the various directives into fragments, managing state like the current section, and so on. - llvm-mc will use the new backend via '-filetype=obj', which may eventually be, but is not yet, since I hear that people like assemblers which actually assemble. - The only thing that works at the moment is changing sections. For the time being I have a Python Mach-O dumping tool in test/scripts so this stuff can be easily tested, eventually I expect to replace this with a real LLVM tool. - More doxyments to come. I assume that since this stuff doesn't touch any of the things which are part of 2.6 that it is ok to put this in not so long before the freeze, but if someone objects let me know, I can pull it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79612 91177308-0d34-0410-b5e6-96231b3b80d8
