Subject: ZEN: Disable stack conservation for GCC
|
|
|
|
|
|
|
|
|
|
There's plenty of room on the stack for a few more inlined bytes here
|
|
|
|
|
and there. The measured stack usage at runtime is still safe without
|
|
|
|
|
this, and performance is surely improved at a microscopic level, so
|
|
|
|
|
remove it.
