Chris Lattnerbbdec032004-06-01 18:13:05 +0000[diff] [blame]65the LLVM and GCC makefiles do not correctly handle spaces in paths. To deal
66with this issue, make sure that your LLVM and GCC source and build trees are

John Criswelldfe6a862004-12-10 15:51:16 +0000[diff] [blame]257 <p><b>Porting to a new architecture:</b> If you are porting the front-end
258 to a new architecture or compiling in a configuration that we have
259 not tried previously, there are probably several changes you will have to make
260 to the GCC target to get it to work correctly. These include:<p>
Brian Gaeke0142c1e2003-10-21 21:58:38 +0000[diff] [blame]261
262 <ul>
John Criswellfc1a1dd2004-11-29 21:46:29 +0000[diff] [blame]263 <li>Often targets include special assembler or linker flags which
Chris Lattnerf9b71182003-10-23 03:55:23 +0000[diff] [blame]264 <tt>gccas</tt>/<tt>gccld</tt> does not understand. In general, these can
265 just be removed.</li>
266 <li>LLVM currently does not support any floating point values other than
267 32-bit and 64-bit IEEE floating point. The primary effect of this is
268 that you may have to map "long double" onto "double".</li>
269 <li>The profiling hooks in GCC do not apply at all to the LLVM front-end.
270 These may need to be disabled.</li>
271 <li>No inline assembly for position independent code. At the LLVM level,
272 everything is position independent.</li>
273 <li>We handle <tt>.init</tt> and <tt>.fini</tt> differently.</li>
Chris Lattnerd6f136c2003-10-24 16:02:34 +0000[diff] [blame]274 <li>You may have to disable multilib support in your target. Using multilib
275 support causes the GCC compiler driver to add a lot of "<tt>-L</tt>"
276 options to the link line, which do not relate to LLVM and confuse
277 <tt>gccld</tt>. To disable multilibs, delete any
278 <tt>MULTILIB_OPTIONS</tt> lines from your target files.</li>
Chris Lattnerf9b71182003-10-23 03:55:23 +0000[diff] [blame]279 <li>Did we mention that we don't support inline assembly? You'll probably
280 have to add some fixinclude hacks to disable it in the system
281 headers.</li>
