* Mips MC object code emission improvements:Bruno Cardoso Lopes2011-11-11
| | | | | | | | | | "With this patch we can now generate runnable Mips code through LLVM direct object emission. We have run numerous simple programs, both C and C++ and with -O0 and -O3 from the output. The code is not production ready, but quite useful for experimentation."

* Rewrite the CMake build to use explicit dependencies between libraries,Chandler Carruth2011-07-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | specified in the same file that the library itself is created. This is more idiomatic for CMake builds, and also allows us to correctly specify dependencies that are missed due to bugs in the GenLibDeps perl script, or change from compiler to compiler. On Linux, this returns CMake to a place where it can relably rebuild several targets of LLVM. I have tried not to change the dependencies from the ones in the current auto-generated file. The only places I've really diverged are in places where I was seeing link failures, and added a dependency. The goal of this patch is not to start changing the dependencies, merely to move them into the correct location, and an explicit form that we can control and change when necessary. This also removes a serialization point in the build because we don't have to scan all the libraries before we begin building various tools. We no longer have a step of the build that regenerates a file inside the source tree. A few other associated cleanups fall out of this. This isn't really finished yet though. After talking to dgregor he urged switching to a single CMake macro to construct libraries with both sources and dependencies in the arguments. Migrating from the two macros to that style will be a follow-up patch. Also, llvm-config is still generated with GenLibDeps.pl, which means it still has slightly buggy dependencies. The internal CMake 'llvm-config-like' macro uses the correct explicitly specified dependencies however. A future patch will switch llvm-config generation (when using CMake) to be based on these deps as well. This may well break Windows. I'm getting a machine set up now to dig into any failures there. If anyone can chime in with problems they see or ideas of how to solve them for Windows, much appreciated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136433 91177308-0d34-0410-b5e6-96231b3b80d8
* Explicitly declare a library dependency of LLVM*Desc toOscar Fuentes2011-07-28
| | | | | | | | | | | | | | | | | | | LLVM*AsmPrinter. GenLibDeps.pl fails to detect vtable references. As this is the only referenced symbol from LLVM*Desc to LLVM*AsmPrinter on optimized builds, the algorithm that creates the list of libraries to be linked into tools doesn't know about the dependency and sometimes places the libraries on the wrong order, yielding error messages like this: ../../lib/libLLVMARMDesc.a(ARMMCTargetDesc.cpp.o): In function `llvm::ARMInstPrinter::ARMInstPrinter(llvm::MCAsmInfo const&)': ARMMCTargetDesc.cpp:(.text._ZN4llvm14ARMInstPrinterC1ERKNS_9MCAsmInfoE [llvm::ARMInstPrinter::ARMInstPrinter(llvm::MCAsmInfo const&)]+0x2a): undefined reference to `vtable for llvm::ARMInstPrinter' git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136328 91177308-0d34-0410-b5e6-96231b3b80d8
* Clean up a pile of hacks in our CMake build relating to TableGen.Chandler Carruth2011-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first problem to fix is to stop creating synthetic *Table_gen targets next to all of the LLVM libraries. These had no real effect as CMake specifies that add_custom_command(OUTPUT ...) directives (what the 'tablegen(...)' stuff expands to) are implicitly added as dependencies to all the rules in that CMakeLists.txt. These synthetic rules started to cause problems as we started more and more heavily using tablegen files from *subdirectories* of the one where they were generated. Within those directories, the set of tablegen outputs was still available and so these synthetic rules added them as dependencies of those subdirectories. However, they were no longer properly associated with the custom command to generate them. Most of the time this "just worked" because something would get to the parent directory first, and run tablegen there. Once run, the files existed and the build proceeded happily. However, as more and more subdirectories have started using this, the probability of this failing to happen has increased. Recently with the MC refactorings, it became quite common for me when touching a large enough number of targets. To add insult to injury, several of the backends *tried* to fix this by adding explicit dependencies back to the parent directory's tablegen rules, but those dependencies didn't work as expected -- they weren't forming a linear chain, they were adding another thread in the race. This patch removes these synthetic rules completely, and adds a much simpler function to declare explicitly that a collection of tablegen'ed files are referenced by other libraries. From that, we can add explicit dependencies from the smaller libraries (such as every architectures Desc library) on this and correctly form a linear sequence. All of the backends are updated to use it, sometimes replacing the existing attempt at adding a dependency, sometimes adding a previously missing dependency edge. Please let me know if this causes any problems, but it fixes a rather persistent and problematic source of build flakiness on our end. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136023 91177308-0d34-0410-b5e6-96231b3b80d8
