| 82 | <p>This document provides <em>usage</em> information about the LLVM makefile |
| 83 | system. While loosely patterned after the BSD makefile system, LLVM has taken |
Chris Lattner | 72f0891 | 2004-10-25 19:28:03 +0000 | [diff] [blame] | 84 | a departure from BSD in order to implement additional features needed by LLVM. |
Reid Spencer | 2734bf7 | 2004-10-31 17:51:38 +0000 | [diff] [blame] | 85 | Although makefile systems such as automake were attempted at one point, it |
| 86 | has become clear that the features needed by LLVM and the Makefile norm are |
| 87 | too great to use a more limited tool. Consequently, LLVM requires simply GNU |
| 88 | Make 3.79, a widely portable makefile processor. LLVM unabashedly makes heavy |
| 89 | use of the features of GNU Make so the dependency on GNU Make is firm. If |
| 90 | you're not familiar with <tt>make</tt>, it is recommended that you read the |
| 91 | <a href="http://www.gnu.org/software/make/manual/make.html">GNU Makefile Manual |

| 105 | building the software, testing it, generating distributions, checking those |

| 114 | <p>The LLVM Makefile System is quite generous. It not only builds its own |
| 115 | software, but it can build yours too. Built into the system is knowledge of |
| 116 | the <tt>llvm/projects</tt> directory. Any directory under <tt>projects</tt> |
| 117 | that has both a <tt>configure</tt> script and a <tt>Makefile</tt> is assumed |
| 118 | to be a project that uses the LLVM Makefile system. This allows your project |

| 224 | <p>Only a few variable definitions are needed to build a regular library. |
| 225 | Normally, the makefile system will build all the software into a single |
| 226 | <tt>libname.o</tt> (pre-linked) object. This means the library is not |
| 227 | searchable and that the distinction between compilation units has been |
| 228 | dissolved. Optionally, you can ask for a shared library (.so), archive library |
| 229 | (.a) or to not have the default (relinked) library built. For example:</p> |
| 230 | <pre><tt> |
| 231 | LIBRARYNAME = mylib |

| 233 | ARCHIVE_LIBRARY = 1 |

| 236 | <p>says to build a library named "mylib" with both a shared library |
| 237 | (<tt>mylib.so</tt>) and an archive library (<tt>mylib.a</tt>) version but |
| 238 | not to build the relinked object (<tt>mylib.o</tt>). The contents of all the |
| 239 | libraries produced will be the same, they are just constructed differently. |
| 240 | Note that you normally do not need to specify the sources involved. The LLVM |
| 241 | Makefile system will infer the source files from the contents of the source |
| 242 | directory.</p> |

| 244 | <tt>SHARED_LIBRARY=1</tt> to indicate that the resulting shared library should |
| 245 | be openable with the <tt>dlopen</tt> function and searchable with the |
| 246 | <tt>dlsym</tt> function (or your operating system's equivalents). While this |

| 286 | </tt></pre> |
| 287 | <p>says that we are to build a tool name <tt>mytool</tt> and that it requires |
| 288 | three libraries: <tt>mylib</tt>, <tt>LLVMSupport.a</tt> and |
| 289 | <tt>LLVMSystem.a</tt>.</p> |
| 290 | <p>Note that two different variables are use to indicate which libraries are |
| 291 | linked: <tt>USEDLIBS</tt> and <tt>LLVMLIBS</tt>. This distinction is necessary |
| 292 | to support projects. <tt>LLVMLIBS</tt> refers to the LLVM libraries found in |
| 293 | the LLVM object directory. <tt>USEDLIBS</tt> refers to the libraries built by |
| 294 | your project. In the case of building LLVM tools, <tt>USEDLIBS</tt> and |
| 295 | <tt>LLVMLIBS</tt> can be used interchangeably since the "project" is LLVM |
| 296 | itself and <tt>USEDLIBS</tt> refers to the same place as <tt>LLVMLIBS</tt>. |
| 297 | </p> |
| 298 | <p>Also note that there are two different ways of specifying a library: with a |
| 299 | <tt>.a</tt> suffix and without. Without the suffix, the entry refers to the |
| 300 | re-linked (.o) file which will include <em>all</em> symbols of the library. |
| 301 | This is useful, for example, to include all passes from a library of passes. |
| 302 | If the <tt>.a</tt> suffix is used then the library is linked as a searchable |
| 303 | library (with the <tt>-l</tt> option). In this case, only the symbols that are |
| 304 | unresolved <em>at that point</em> will be resolved from the library, if they |
| 305 | exist. Other (unreferenced) symbols will not be included when the <tt>.a</tt> |
| 306 | syntax is used. Note that in order to use the <tt>.a</tt> suffix, the library |
| 307 | in question must have been built with the <tt>ARCHIVE_LIBRARY</tt> option set. |

| 314 | <p>Many tools will want to use the JIT features of LLVM. However, getting the |
| 315 | right set of libraries to link with is tedious, platform specific, and error |
| 316 | prone. Additionally, the JIT has special linker switch options that it needs. |
| 317 | Consequently, to make it easier to build tools that use the JIT, you can |
Reid Spencer | 6f14a5b | 2004-11-29 07:47:16 +0000 | [diff] [blame] | 318 | use a special value for the <tt>LLVMLIBS</tt> variable:</p> |
Reid Spencer | 31ce7fb | 2004-11-29 07:44:51 +0000 | [diff] [blame] | 319 | <pre><tt> |
| 320 | TOOLNAME = my_jit_tool |
| 321 | USEDLIBS = mylib |
| 322 | LLVMLIBS = JIT |
| 323 | </tt></pre> |
| 324 | <p>Using a value of <tt>JIT</tt> for <tt>LLVMLIBS</tt> tells the makefile |
| 325 | system to construct a special value for LLVMLIBS that gives the program all |
| 326 | the LLVM libraries needed to run the JIT. Any additional libraries needed can |
| 327 | still be specified with <tt>USEDLIBS</tt>. To get a full understanding of how |
| 328 | this changes the linker command, it is recommended that you:</p> |
| 329 | <pre><tt> |
| 330 | cd examples/Fibonacci |
| 331 | make VERBOSE=1 |
| 332 | </tt></pre> |
| 333 | <p>By default, using <tt>LLVMLIBS=JIT</tt> will link in enough to support JIT |
| 334 | code generation for the architecture on which the tool is linked. If you need |
| 335 | additional target architectures linked in, you may specify them on the command |
| 336 | line or in your <tt>Makefile</tt>. For example:</p> |
| 337 | <pre><tt> |
| 338 | ENABLE_X86_JIT=1 |
| 339 | ENABLE_SPARCV9_JIT=1 |
| 340 | ENALBE_PPC_JIT=1 |
| 341 | </tt></pre> |
| 342 | <p>will cause the tool to be able to generate code for all three platforms. |
