Last week AMD published a "add znver1 processor" patch to the GNU Binutils package. This patch doesn't mention Zen explicitly but "znver1" is short for Zen after their long run of bdverX codenames within Binutils, GCC, etc, for indicating the Bulldozer architecture.
This patch reveals the AMD Zen design no longer supports TBM, FMA4, XOP, or LWP ISAs. Meanwhile the new ISA additions are for SMAP, RDSEED, SHA, XSAVEC, XSAVES, CLFLUSHOPT, and ADCX: ISAs are supported. It's nice to see with Zen that AMD will support the RDSEED instruction, which Intel has added since Broadwell for seeding another pseudorandom number generator. SMAP is short for the Supervisor Mode Access Prevention and is another Intel instruction set extension already supported by Linux.
P.S keep it civil and drop the doom and gloom.
