[PATCH 1/8] Hexagon (target/hexagon) fix bug in circular addressing |
Date: |
Sun, 6 Feb 2022 15:50:23 -0800 |
From: Michael Lambert <mlambert@quicinc.com>
Versions V3 and earlier should treat the "K_const" and "length" values
as unsigned.
Modified circ_test_v3() in tests/tcg/hexagon/circ.c to reproduce the bug
