- Source files of SR
- .PP
- The sources of SR are in the following files
- and packages:
- .IP sr.h: 14
- declarations of global variables and
- data structures
- .IP sr.c:
- the routine main; a driving routine to process
- (possibly nested) loops in the right order
- .IP iv
- implements a procedure that finds the induction variables
- of a loop
- .IP reduce
- implements a procedure that finds optimizable expressions
- and that does the transformations
- .IP cand
- implements a procedure that finds the candidate induction
- variables; used to implement iv
- .IP xform
- implements several useful routines that transform
- lists of EM text or a CFG; used to implement reduce
- .IP expr
- implements a procedure that parses iv-expressions
- .IP aux
- implements several auxiliary procedures.
