There was a problem hiding this comment.
Hi @ksco
There are no struct lbt_context, struct sctx_info, unsigned long long __extcontext[0] __attribute__((__aligned__(16))); for LA64_ABI_1.
How about get_feature_flags_by_cpucfg and then _features & CPU_LBT_X86? jdk works both for LA64 ABI 1.0 and 2.0.
Thanks,
Leslie Zhai
