This can't go in until a Linux kernel is released with this constant since this is bits/hwcap.h and is included in sys/auxv.h and would make the constant visible to the users. You use HWCAP_GCS internally in a couple of places, so you could put this into another header temporarily to support building glibc without exposing the constant in the release. > --- > sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h | 1 + > 1 file changed, 1 insertion(+) > > diff --git a/sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h b/sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h > index 2fa158fcc0..47836eb414 100644 > --- a/sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h > +++ b/sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h > @@ -54,6 +54,7 @@ > #define HWCAP_SB (1 << 29) > #define HWCAP_PACA (1 << 30) > #define HWCAP_PACG (1UL << 31) > +#define HWCAP_GCS (1UL << 32) > > #define HWCAP2_DCPODP (1 << 0) > #define HWCAP2_SVE2 (1 << 1) Cheers, Carlos.
