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