Bug ID: 117408
Summary: ICE on `#pragma arm "arm_mve.h" false`
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: azoff at gcc dot gnu.org
Target Milestone: ---
Starting in r14-435-g00d97bf3b5a, GCC ICEs if `#pragma arm "arm_mve.h" false`
or `#pragma arm "arm_mve.h" true` is issued in a compile unit that does not
have `#pragma arm "arm_mve_types.h"` before.
Reproducer:
/* { dg-do compile } */
/* { dg-require-effective-target arm_v8_1m_mve_ok } */
/* { dg-add-options arm_v8_1m_mve } */
/* It doesn't really matter if this produces errors missing types,
but it mustn't trigger an ICE. */
#pragma GCC arm "arm_mve.h" false /* { dg-error "this definition requires MVE
types" } */
Example ICE:
foo.c:7:9: internal compiler error: Segmentation fault
7 | #pragma GCC arm "arm_mve.h" false /* { dg-error "this definition
requires MVE types" } */
