Brian Gaeke | b0fd761 | 2004-05-09 05:28:35 +0000 | [diff] [blame] | 226 | <p>The core LLVM infrastructure uses |
| 227 | <a href="http://www.gnu.org/software/autoconf/">GNU autoconf</a> to adapt itself |
| 228 | to the machine and operating system on which it is built. However, minor |
| 229 | porting may be required to get LLVM to work on new platforms. We welcome your |
| 230 | portability patches and reports of successful builds or error messages.</p> |

| 490 | </div> |
| 491 | |
| 492 | <div class="doc_text"> |
| 493 | The llvm-gcc 4.2 Ada compiler works fairly well, however this is not a mature |
| 494 | technology and problems should be expected. |
| 495 | <ul> |
| 496 | <li>The Ada front-end currently only builds on x86-32. This is mainly due |
| 497 | to lack of trampoline support (pointers to nested functions) on other platforms, |
| 498 | however it <a href="http://llvm.org/PR2006">also fails to build on x86-64</a> |
| 499 | which does support trampolines.</li> |
| 500 | <li>The Ada front-end <a href="http://llvm.org/PR2007">fails to bootstrap</a>. |
| 501 | Workaround: configure with --disable-bootstrap.</li> |
| 502 | <li>The c380004 and <a href="http://llvm.org/PR2010">c393010</a> ACATS tests |
| 503 | fail (c380004 also fails with gcc-4.2 mainline).</li> |
| 504 | <li>Many gcc specific Ada tests continue to crash the compiler.</li> |
| 505 | <li>The -E binder option (exception backtraces) |
| 506 | <a href="http://llvm.org/PR1982">does not work</a> and will result in programs |
| 507 | crashing if an exception is raised. Workaround: do not use -E.</li> |
| 508 | <li>Only discrete types <a href="http://llvm.org/PR1981">are allowed to start |
| 509 | or finish at a non-byte offset</a> in a record. Workaround: do not pack records |
| 510 | or use representation clauses that result in a field of a non-discrete type |
| 511 | starting or finishing in the middle of a byte.</li> |
| 512 | <li>The lli interpreter <a href="http://llvm.org/PR2009">considers 'main' |
| 513 | as generated by the Ada binder to be invalid</a>. |
| 514 | Workaround: hand edit the file to use pointers for argv and envp rather than |
| 515 | integers.</li> |
| 516 | <li>The -fstack-check option <a href="http://llvm.org/PR2008">is ignored</a>.</li> |
