/*
|
|
* Special ".note" entry to tag an Android binary and specify the ABI version.
|
|
*
|
|
* For all arches except sparc, gcc emits the section directive for the
|
|
* following struct with a PROGBITS type. However, the section should be
|
|
* of NOTE type, according to the Generic SysV ABI spec.
|
|
*
|
|
* 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.
