Bug ID: 108442 Summary: arm: MVE's vld1* and vst1* do not work when __ARM_MVE_PRESERVE_USER_NAMESPACE is defined Product: gcc Version: 10.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: avieira at gcc dot gnu.org Target Milestone: --- When compiling: $ cat t.c #include <arm_mve.h> uint32x4_t foo (uint32_t *p) { return __arm_vld1q_u32 (p); } with: $ arm-none-eabi-gcc -march=armv8.1-m.main+mve -mfloat-abi=hard -D__ARM_MVE_PRESERVE_USER_NAMESPACE it will fail to compile as __arm_vld1q_u32 is defined in arm_mve.h as calling vldrwq_u32 which will not exist when __ARM_MVE_PRESERVE_USER_NAMESPACE is defined.
