| 180 | The SPARC V8 backend is still beta quality software. Unless you are working on |

John Criswell | 9e2485c | 2004-12-10 15:51:16 +0000 | [diff] [blame] | 213 | <p><b>Porting to a new architecture:</b> If you are porting the front-end |
| 214 | to a new architecture or compiling in a configuration that we have |
| 215 | not tried previously, there are probably several changes you will have to make |
| 216 | to the GCC target to get it to work correctly. These include:<p> |
Brian Gaeke | 46079d2 | 2003-10-21 21:58:38 +0000 | [diff] [blame] | 217 | |
| 218 | <ul> |
John Criswell | 6e35eda | 2004-11-29 21:46:29 +0000 | [diff] [blame] | 219 | <li>Often targets include special assembler or linker flags which |
Chris Lattner | e38c628 | 2003-10-23 03:55:23 +0000 | [diff] [blame] | 220 | <tt>gccas</tt>/<tt>gccld</tt> does not understand. In general, these can |
| 221 | just be removed.</li> |
| 222 | <li>LLVM currently does not support any floating point values other than |
| 223 | 32-bit and 64-bit IEEE floating point. The primary effect of this is |
| 224 | that you may have to map "long double" onto "double".</li> |
| 225 | <li>The profiling hooks in GCC do not apply at all to the LLVM front-end. |
| 226 | These may need to be disabled.</li> |
| 227 | <li>No inline assembly for position independent code. At the LLVM level, |
| 228 | everything is position independent.</li> |
| 229 | <li>We handle <tt>.init</tt> and <tt>.fini</tt> differently.</li> |
Chris Lattner | 13964e0 | 2003-10-24 16:02:34 +0000 | [diff] [blame] | 230 | <li>You may have to disable multilib support in your target. Using multilib |
| 231 | support causes the GCC compiler driver to add a lot of "<tt>-L</tt>" |
| 232 | options to the link line, which do not relate to LLVM and confuse |
| 233 | <tt>gccld</tt>. To disable multilibs, delete any |
| 234 | <tt>MULTILIB_OPTIONS</tt> lines from your target files.</li> |
Chris Lattner | e38c628 | 2003-10-23 03:55:23 +0000 | [diff] [blame] | 235 | <li>Did we mention that we don't support inline assembly? You'll probably |
| 236 | have to add some fixinclude hacks to disable it in the system |
| 237 | headers.</li> |
