Bug ID: 92051
Summary: Many aarch64 SVE tests fail with ICE (expected
integer_cst, have poly_int_cst in to_wide)
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: sje at gcc dot gnu.org
Target Milestone: ---
I am seeing several hundred aarch64 sve tests fail with an ICE since Oct 8,
2019. One such failure is gcc.target/aarch64/sve/while_1.c, the ICE is:
