Chris Lattnerbbdec032004-06-01 18:13:05 +0000[diff] [blame]68the LLVM and GCC makefiles do not correctly handle spaces in paths. To deal
Bill Wendlingae2a3092006-11-16 09:31:19 +0000[diff] [blame^]69with this issue, make sure that your LLVM and GCC source and build trees are
70located in a top-level directory (like <tt>/cygdrive/c/llvm</tt> and
Chris Lattnerbbdec032004-06-01 18:13:05 +0000[diff] [blame]71<tt>/cygdrive/c/llvm-cfrontend</tt>), not in a directory that contains a space
Bill Wendlingae2a3092006-11-16 09:31:19 +0000[diff] [blame^]72(which includes your "home directory", because it lives under the "Documents and
73Settings" directory). We welcome patches to fix this issue.</p>

Reid Spencer3e41cd52004-12-22 09:52:30 +0000[diff] [blame]75<p>It has been found that the GCC 3.3.3 compiler provided with recent Cygwin
John Criswell93c7fff2005-10-24 16:37:24 +0000[diff] [blame]76versions is incapable of compiling the LLVM GCC front-end correctly. If your
Bill Wendlingae2a3092006-11-16 09:31:19 +0000[diff] [blame^]77Cygwin installation includes GCC 3.3.3, we <em>strongly</em> recommend that you
78download GCC 3.4.3, build it separately, and use it for compiling the LLVM GCC

270 <p><b>Solaris/SPARC:</b></p>
271
272 <p>The GCC front-end can be configured for either SPARC V8 (32 bit) or
273 SPARC V9 (64 bit). This changes, among other things, the sizes of
274 integer types and the macros defined for conditional compilation.</p>
275
276 <p>The SPARC V8 ABI support is more robust than the V9 ABI support and can
277 generate SPARC V9 code. It is highly recommended that you use the V8
278 ABI with LLVM, as shown below. Also, note that Solaris has trouble
279 with various wide (multibyte) character functions from C as referenced
280 from C++, so we typically configure with --disable-c-mbchar (cf. <a
281 href="http://llvm.org/PR206">Bug 206</a>).</p>

293 <p><b>Common Problem:</b> You may get error messages regarding the fact
294 that LLVM does not support inline assembly. Here are two common
295 fixes:</p>
296
297 <ul>
298 <li><p><b>Fix 1:</b> If you have system header files that include inline
299 assembly, you may have to modify them to remove the inline assembly
300 and install the modified versions in
301 <code>$CFEINSTALL/lib/gcc/<i>target-triplet</i>/3.4-llvm/include</code>.</li>
302
303 <li><b>Fix 2:</b> If you are building the C++ front-end on a CPU we
304 haven't tried yet, you will probably have to edit the appropriate
305 version of atomicity.h under
306 <code>src/libstdc++-v3/config/cpu/<i>name-of-cpu</i>/atomicity.h</code>
307 and apply a patch so that it does not use inline assembly.</li>
308 </ul>
309
310 <p><b>Porting to a new architecture:</b> If you are porting the front-end
311 to a new architecture or compiling in a configuration that we have not
312 tried previously, there are probably several changes you will have to
313 make to the GCC target to get it to work correctly. These include:</p>
314
315 <ul>
316 <li>Often targets include special assembler or linker flags which
317 <tt>gccas</tt>/<tt>gccld</tt> does not understand. In general,
318 these can just be removed.</li>
319
320 <li>LLVM currently does not support any floating point values other than
321 32-bit and 64-bit IEEE floating point. The primary effect of this
322 is that you may have to map "long double" onto "double".</li>
323
324 <li>The profiling hooks in GCC do not apply at all to the LLVM
325 front-end. These may need to be disabled.</li>
326
327 <li>No inline assembly for position independent code. At the LLVM
328 level, everything is position independent.</li>
329
330 <li>We handle <tt>.init</tt> and <tt>.fini</tt> differently.</li>
331
332 <li>You may have to disable multilib support in your target. Using
333 multilib support causes the GCC compiler driver to add a lot of
334 "<tt>-L</tt>" options to the link line, which do not relate to LLVM
335 and confuse <tt>gccld</tt>. To disable multilibs, delete any
336 <tt>MULTILIB_OPTIONS</tt> lines from your target files.</li>
337
338 <li>Did we mention that we don't support inline assembly? You'll
339 probably have to add some fixinclude hacks to disable it in the
340 system headers.</li>
341 </ul></li>
342
343 <li><p>Put <tt>$CFEINSTALL/bin</tt> into your <tt>PATH</tt> environment
344 variable.</p>
345
346<div class="doc_code">
347csh:
348<pre>
349 % setenv PATH $CFEINSTALL/bin:$PATH
350</pre>
351sh:
352<pre>
353 % export PATH=$CFEINSTALL/bin:$PATH
354</pre>
355</div>
356 </li>
357
358 <li><p>Go back into the LLVM source tree proper. Rerun configure, using the
359 same options as the last time. This will cause the configuration to now
360 find the newly built llvm-gcc and llvm-g++ executables. </p></li>
361
362 <li><p>Rebuild your CVS tree. This shouldn't cause the whole thing to be
363 rebuilt, but it should build the runtime libraries. After the tree is
364 built, install the runtime libraries into your GCC front-end build tree.
365 These are the commands you need:</p>
366
367<div class="doc_code">
368<pre>
369% gmake
370% gmake -C runtime install-bytecode
371</pre>
372</div>
373 </li>
374
375 <li><p>Optionally, build a symbol table for the newly installed runtime
376 libraries. Although this step is optional, you are strongly encouraged to
377 do this as the symbol tables will make a significant difference in your
378 link times. Use the <tt>llvm-ranlib</tt> tool to do this, as follows:</p>
379
380<div class="doc_code">
381<pre>
382% cd $CFEINSTALL/lib
383% llvm-ranlib libiberty.a
384% llvm-ranlib libstdc++.a
385% llvm-ranlib libsupc++.a
386% cd $CFEINSTALL/lib/gcc/<i>target-triplet</i>/3.4-llvm
387% llvm-ranlib libgcc.a
388% llvm-ranlib libgcov.a
389</pre>
390</div>
391 </li>
392
393 <li><p>Test the newly-installed C frontend by one or more of the following
394 means:</p>
395
396 <ul>
397 <li>running the feature &amp; regression tests via <tt>make
398 check</tt></li>
399 <li>compiling and running a "hello, LLVM" program in C and C++.</li>
400 <li>running the tests found in the <tt>llvm-test</tt> CVS module</li>
401 </ul></li>
