181 | b64 is an empty option. The native linker uses -b64 for xcoff64 support | |
182 | Our linker uses -m aixppc64 for xcoff64 support. The choice for the | |
183 | correct emulation is done in collect2.c via the environmental varible | |
184 | LDEMULATION. | |
185 | ||
186 | binitfini has special handling in the linker backend. The native linker | |
187 | uses the arguemnts to generate a table of init and fini functions for | |
188 | the executable. The important use for this option is to support aix 4.2+ | |
189 | c++ constructors and destructors. This is tied into gcc via collect2.c. | |
190 | The function table is accessed by the runtime linker/loader by checking if | |
191 | the first symbol in the loader symbol table is "__rtinit". The native | |
192 | linker generates this table and the loader symbol. The gnu linker looks | |
193 | for the symbol "__rtinit" and makes it the first loader symbol. It is the | |
194 | responsiblity of the user to define the __rtinit symbol. The format for | |
195 | __rtinit is given by the aix system file /usr/include/rtinit.h. You can | |
196 | look at collect2.c to see an example of how this is done for 32 and 64 bit. | |
197 | Below is an exmaple of a 32 bit assembly file that defines __rtinit. | |
