Subject: [PATCH v2] getauxval.3: MIPS, AT_BASE_PLATFORM passes ISA level
Date: Sun, 22 Mar 2020 17:55:27 +0800
Message-ID: <> (raw)

Since Linux 5.7, on MIPS, we use AT_BASE_PLATFORM to pass ISA level.
The values may be:
  mips2, mips3, mips4, mips5,
  mips32, mips32r2, mips32r6,
  mips64, mips64r2, mips64r6.

This behavior is different with PowerPC.
