Bug ID: 112527
Summary: RVV integer vector instructions generated with
rv64gc_zvfh
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: rdapp at gcc dot gnu.org
CC: juzhe.zhong at rivai dot ai, kito.cheng at gmail dot com
Target Milestone: ---
Target: riscv
While trying something else I noticed that when compiling without V but with
Zvfh the following FAILs:
/* { dg-do compile } */
/* { dg-additional-options "-std=c99 -march=rv64gc_zvfh -mabi=lp64d
--param=riscv-autovec-preference=scalable -O3" } */
#include <stdint-gcc.h>
#define TEST_TYPE(TYPE) \
__attribute__((noipa)) \
void vadd_##TYPE (TYPE *dst, TYPE *a, TYPE *b, int n) \
{ \
for (int i = 0; i < n; i++) \
dst[i] = a[i] + b[i]; \
}
TEST_TYPE(int8_t) \
TEST_TYPE(uint8_t) \
TEST_TYPE(int16_t) \
TEST_TYPE(uint16_t) \
TEST_TYPE(int32_t) \
TEST_TYPE(uint32_t) \
TEST_TYPE(int64_t) \
TEST_TYPE(uint64_t) \
/* { dg-final { scan-assembler-not {\tvadd\.vv} } } */
Haven't yet checked why, probably just an oversight, but shouldn't be like
that.
