Bug ID: 94574
Summary: aarch64: ICE during GIMPLE pass:ccp
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: yangyang305 at huawei dot com
Target Milestone: ---
Hi, gcc-10 ICEs when compiling the following testcase with -O2
-msve-vector-bits=256 -march=armv8.2-a+sve
test case: gcc/testsuite/gcc.target/aarch64/sve/acle/general/deref_1.c
---
/* { dg-options "-O2" } */
#include <arm_sve.h>
uint64_t
f1 (int32_t *x, int32_t *y)
{
union { uint64_t x; char c[8]; } u;
svbool_t pg = svptrue_b32 ();
*(svbool_t *)&u.c[0] = svcmpeq (pg, svld1 (pg, x), 0);
*(svbool_t *)&u.c[4] = svcmpeq (pg, svld1 (pg, y), 1);
return u.x;
}
typedef unsigned int v4si __attribute__((vector_size(16)));
/* The aliasing is somewhat dubious here, but it must compile. */
v4si
f2 (void)
{
v4si res;
*(svuint32_t *) &res = svindex_u32 (0, 1);
return res;
}

GCC version: 10.0.1 20200413 (experimental)
Result:

PR tree-optimization/94574 - aarch64: ICE during GIMPLE pass:ccp
In this PR the testcase ICEs because a BIT_INSERT_EXPR whose replaced bits
are
not fully inside the container is generated. A size check is added to avoid
this kind of ICE.
gcc/ChangeLog:
PR tree-optimization/94574
* tree-ssa.c (non_rewritable_lvalue_p): Add size check when
analyzing
whether a vector-insert is rewritable using a BIT_INSERT_EXPR.
gcc/testsuite/ChangeLog:
PR tree-optimization/94574
* gcc.dg/pr94574.c: New test.
