/* A very dirty trick: gcc emits references to __divdi3, __udivdi3,
|
|
__moddi3, and __umoddi3. These functions are exported and
|
|
therefore we get PLTs. Unnecessarily so. Changing gcc is a big
|
|
task which might not be worth it so we play tricks with the
|
|
assembler.
|
|
Note: in_divdi3_c is only used to avoid symbol alias on divdi3
|
|
build itself. */
