* for more information. | |||||
* | |||||
* For all arches except sparc, gcc emits the section directive for the | |||||
* following struct with a PROGBITS type. However, newer versions of binutils | |||||
* (after 2.16.90) require the section to be of NOTE type, to guarantee that the | |||||
* .note.ABI-tag section correctly ends up in the first page of the final | |||||
* executable. | |||||
* | |||||
* Unfortunately, there is no clean way to tell gcc to use another section type, | |||||
* so this C file (or the C file that includes it) must be compiled in multiple | |||||
* steps: | |||||
* | |||||
* - Compile the .c file to a .s file. | |||||
* - Edit the .s file to change the 'progbits' type to 'note', for the section | |||||
* directive that defines the .note.ABI-tag section. | |||||
* - Compile the .s file to an object file. | |||||
* | |||||
* These steps are done in the invididual Makefiles for each applicable arch. | |||||
