/**
|
|
* To determine variable order for .bss, the compiler sorts variables by their
|
|
* "name index" mod 256, where name index is something that, with -g, gets
|
|
* incremented by struct and variable declarations, typedefs, and file markers,
|
|
* among else. (Without -g, only variable declarations affects the index.)
|
|
* This file contains enough dummy declarations to bump the index by 128.
|
|
* Including it, or removing the include, should fix bss reordering problems
|
|
* for a file, assuming the name index distance between its first and last bss
|
|
* variable is at most 128.
|
|
* Note that if a variable is declared "extern" within a header file, the name
|
|
* index is taken at that point of the extern declaration. Thus, this include
|
|
* must come before any such header.
