Bug ID: 96429
Summary: d: Pointer subtraction uses TRUNC_DIV_EXPR
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: d
Assignee: ibuclaw at gdcproject dot org
Reporter: ibuclaw at gdcproject dot org
Target Milestone: ---
Given the pointer operation:
long delta = smaller & (read - first);
This gets lowered as (-fdump-tree-original)
long delta = (long) smaller & (read - first) / 8;
Instead of...
long delta = (long) smaller & (read - first) /[ex] 8;
Switching will likely give some marginal gains on performance.
