Bug ID: 125307
Summary: Gswitch cases should take an edge or a bb instead of a
label once in cfg mode
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Keywords: compile-time-hog
Severity: enhancement
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
Gswitch cases take a hi, low and label.
But really the label should either be an edge or a basic block.
This is both a compile time improvement and a memory usage issue.
Everytime we need to figure out where the case goes to you need to go searching
each block for the label. That is just bad news and it is a linear search too.
