| 35 | <PRE> This looks like the GCC __builtin_apply() bug I reported to the GCC | |
| 36 | team a while back (<A HREF="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=8028">http://gcc.gnu.org/bugzilla/show_bug.cgi?id=8028</A>). The | |
| 37 | configure script should detect and work around this, though; I'm not sure | |
| 38 | why not. I'll take a closer look at this report and see if I can figure | |
| 39 | the problem out. | |

| 41 | ><i>I am wondering what the constant 64 means in: | |
| 42 | </I>><i>extsyms.c: | |
| 43 | </I>><i> | |
| 44 | </I>><i>static void *__dblocal_##func##_stub(void) { \ | |
| 45 | </I>><i> __dblocal_##func##_stub0(); \ | |
| 46 | </I>><i> __builtin_return(__builtin_apply((void *)__dblocal_##func, \ | |
| 47 | </I>><i> __builtin_apply_args(), 64)); \ | |
| 48 | </I>><i>} \ | |
| 49 | </I> | |
| 50 | This is more suited to the -coding list, but 64 is the argument space | |
| 51 | reserved for the called function--I use 64 as an arbitrary value larger | |
| 52 | than anything that will actually be passed. See the GCC documentation for | |
| 53 | details on how __builtin_apply() works. | |
