If it may help a bit, please also review/check the current status of Y2038 work. Some Y2038 related work (mostly for ARM32) may be also helpful as well (as some patches for RV32 also do the conversion for other architectures). https://github.com/lmajewski/y2038_glibc/commits/y2038_edge Please also find the meta layer for testing Y2038 (with some basic test suite) code on qemu-arm and Yocto/OE: https://github.com/lmajewski/meta-y2038 (it shall also be easy to extend this meta layer to add support for ARC as well). >=20 > Thx, > -Vineet Best regards, Lukasz Majewski -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-59 Fax: (+49)-8142-66989-80 Email: lukma@denx.de --Sig_/NPXF1XeD+kwUQYD5.yJ+nIN Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature Content-length: 488 -----BEGIN PGP SIGNATURE----- iQEzBAEBCgAdFiEEgAyFJ+N6uu6+XupJAR8vZIA0zr0FAl4/+sEACgkQAR8vZIA0 zr3LCQgAs7L2YJV2FRM2x6OVddFlnuhuCsbzbrpbIdTYzCd7Bkivrq8GX5qUg93r xA/53JrSxQlkHm8ZvwFCz9KBsu5Op2ZpWIdEgwm/qe05vxoz/hNzkpdO5+msrCxy +Fo4Qgy3gmm9xrB2CFTMhvarQexWHYrD4qA2dVhx4bcXXMUTUA/1Tdr6447nuiwB KbGthNNDUOQrq0MVsxgX6jIAIBWa8cy8J/DqJ3OQ3gEKFL1ZoKMie4f7Km3Crclz jkpJ/ygeTxl9aECZWFALdFLeF2WAnERJfF8fSecHzfKHxBoF74PeETzIJUnbC6Me YJH3wqY8IEQF2rmA5MVkhR3IR8NapA== =VsxK -----END PGP SIGNATURE----- --Sig_/NPXF1XeD+kwUQYD5.yJ+nIN--
