SDE does not run on FreeBSD, and setting up Linux (or Windows) for this is out of question, at least for me. >=20 > gcc: http://gcc.gnu.org/wiki/Intel%20MPX%20support%20in%20the%20GCC%20com= piler >=20 > glibc: > https://sourceware.org/ml/libc-alpha/2014-03/msg00491.html > https://sourceware.org/ml/libc-alpha/2014-03/msg00543.html > https://sourceware.org/ml/libc-alpha/2014-03/msg00605.html I can google as well. I have no intend of reverse-engineering Linux code to get basic information about CPU core. Why are you so insisted on the non-released feature, which seemingly still lacks complete documentation ? Yes, something can be done even now, but that requires a lot of efforts, backed by a huge belief into the world-shaking nature of the MPX and inability to wait even a bit to get hands on it. I do not have that urge, and do not understand why do you try to trick others into it. Will you provide the hardware to the developers when it become generally avaiable ? FWIW, it would be very useful if Jim Harris chimed in. --xK0oco9ieugCOMaM Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBAgAGBQJUF/XmAAoJEJDCuSvBvK1BDvMP/0f0HNbeaUpRF71UiTPVMukz yRp2RzduC9/+GPnDW2rB/nZsU8r57lFcpgvaS7aOAfN2iol47ve3eLwGJ1WbzJoS Tkmd18U0BBEA0nLaZqraXIu7j9e9gMLJvDOEPOD525esc/S6xs4MYKl278HFkrjQ lTLWoTzA906uL8hIho02FojuoyXTGgEFX+obM4pEj92kkpAzSssjDXa3wqUibjuP sCmP5JCcWLbX2iAe3Fi1cRI1ATCAVEuJmekR27vZIqZzIzZN1BGsSE0cL8XYcsCl B1/vGVCYfJhwVanD2mvAZ3wKt/flgcrokGQRBBx22/7euXeAvfZpBJpCmKyx7Iqt c1mni6SUflNgtu6aoZ5dtTRiwhdGO0cpruxcwP8DQmlg1VpoCgDAAMtC0gPbjuxx 8Y+3704w2auyzwVP+9somCD4ujswRcJadyaPWhF1h6Z38NRg3IkSe0kYDIVJmxQ1 A6wvIM18Xh4F1z0ZN4xtlD4egin4RM93DycusoL66YbeYz75i6rBW9mJFXO5VnGm 1G7TPSDSyrfojWfrGDoBHNbWzeXZEeEigCqiWvur2yb+Zw1bFU67KqVbZDSWP1ay 6S4dLV2bIPiuLB79CA+tojP9FhuO26DlYjMxy1W1pux5v85d9qe4rwX6ndu5+u79 p4/MNHC7rCzGIZG4AKi4 =4nTq -----END PGP SIGNATURE----- --xK0oco9ieugCOMaM--
