Bug ID: 120405
Summary: bfloat16-complex.c fails with -mcpu=neoverse-v2 but
works with -mcpu=cortex-a57
Product: gcc
Version: 14.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: ramana at gcc dot gnu.org
Target Milestone: ---
Strangely the testcase gcc.dg/bfloat16-complex.c passes with base v8 but fails
with v8.2 and above with the link time error as below at all optimization
levels.

/usr/bin/ld: ./bfloat16-complex.o: in function `main':
bfloat16-complex.c:(.text+0x6d4): undefined reference to `__mulbc3'
/usr/bin/ld: bfloat16-complex.c:(.text+0x76c): undefined reference to
`__divbc3'
Hit while testing the RC for 14.3 with a compiler that defaults to neoverse-v2
. Will try trunk next.
