/* This file gathers information about how variables whose scope is

The transitive call site specific clobber effects are computed

for the variables whose scope is contained within this compilation

|

|

First each function and static variable initialization is analyzed
|

to determine which local static variables are either read, written,

or have their address taken. Any local static that has its address
|

taken is removed from consideration. Once the local read and

writes are determined, a transitive closure of this information is
|
||
performed over the call graph to determine the worst case set of
|
||
side effects of each call. In later parts of the compiler, these
|
||
local and global sets are examined to make the call clobbering less
|
||
traumatic, promote some statics to registers, and improve aliasing

information. */
