John Criswelldfe6a862004-12-10 15:51:16 +0000[diff] [blame]62<p>If you are building LLVM and the GCC front-end under Cygwin, please note that
Chris Lattnerbbdec032004-06-01 18:13:05 +0000[diff] [blame]63the LLVM and GCC makefiles do not correctly handle spaces in paths. To deal
64with this issue, make sure that your LLVM and GCC source and build trees are
65located in a top-level directory (like <tt>/cygdrive/c/llvm</tt> and
66<tt>/cygdrive/c/llvm-cfrontend</tt>), not in a directory that contains a space
67(which includes your "home directory", because it lives under the "Documents

Chris Lattner51473c32006-02-05 06:44:17 +0000[diff] [blame]198The SPARC V8 ABI support is more robust than the V9 ABI support and can generate

217
218 <ul>
219 <li><p><b>Fix 1:</b> If you have system header files that include
220 inline assembly, you may have to modify them to remove the inline

224 <li><b>Fix 2:</b> If you are building the C++ front-end on a CPU we

227 <code>src/libstdc++-v3/config/cpu/<i>name-of-cpu</i>/atomicity.h</code>
Misha Brukman4478f2b2004-05-12 18:49:47 +0000[diff] [blame]228 and apply a patch so that it does not use inline assembly.</li>

232 to a new architecture or compiling in a configuration that we have

Brian Gaeke0142c1e2003-10-21 21:58:38 +0000[diff] [blame]235
236 <ul>
John Criswellfc1a1dd2004-11-29 21:46:29 +0000[diff] [blame]237 <li>Often targets include special assembler or linker flags which
Chris Lattnerf9b71182003-10-23 03:55:23 +0000[diff] [blame]238 <tt>gccas</tt>/<tt>gccld</tt> does not understand. In general, these can
239 just be removed.</li>
240 <li>LLVM currently does not support any floating point values other than
241 32-bit and 64-bit IEEE floating point. The primary effect of this is
242 that you may have to map "long double" onto "double".</li>
243 <li>The profiling hooks in GCC do not apply at all to the LLVM front-end.
244 These may need to be disabled.</li>
245 <li>No inline assembly for position independent code. At the LLVM level,
246 everything is position independent.</li>
247 <li>We handle <tt>.init</tt> and <tt>.fini</tt> differently.</li>
Chris Lattnerd6f136c2003-10-24 16:02:34 +0000[diff] [blame]248 <li>You may have to disable multilib support in your target. Using multilib
249 support causes the GCC compiler driver to add a lot of "<tt>-L</tt>"
250 options to the link line, which do not relate to LLVM and confuse
251 <tt>gccld</tt>. To disable multilibs, delete any
252 <tt>MULTILIB_OPTIONS</tt> lines from your target files.</li>
Chris Lattnerf9b71182003-10-23 03:55:23 +0000[diff] [blame]253 <li>Did we mention that we don't support inline assembly? You'll probably
254 have to add some fixinclude hacks to disable it in the system
255 headers.</li>

272 rebuilt, but it should build the runtime libraries. After the tree is
John Criswelldfe6a862004-12-10 15:51:16 +0000[diff] [blame]273 built, install the runtime libraries into your GCC front-end build tree.
Misha Brukmana9b86762005-03-01 17:15:23 +0000[diff] [blame]274 These are the commands you need:</p>
