| 22 | # The existence of a symbol __start (or _start) should overrule Main, so | |
| 23 | # it can be a user symbol without the associated mmixal magic. We | |
| 24 | # also want to provide Main as a synonym for _start, if Main wasn't | |
| 25 | # defined but is referred to, and _start was defined. | |
| 26 | # | |
| 27 | # The reason we use a symbol "_start." as a mediator is to avoid | |
| 28 | # causing ld to force the type of _start to object rather than no | |
| 29 | # type, which confuses disassembly; we also make it alphanumerically | |
| 30 | # a successor of _start for similar reasons. Perhaps it's a linker | |
| 31 | # bug that linker-defined symbols set the symbol-type. | |
| 32 | # | |
| 33 | # Note that we smuggle this into OTHER_TEXT_SECTIONS (at the end | |
| 34 | # of .text) rather than TEXT_START_SYMBOLS. This is necessary, as | |
| 35 | # DEFINED wouldn't find the symbol if it was at the top; presumably | |
| 36 | # before the definition, if the definition is not in the first file. | |
