| Subject | [PATCH v6 16/17] arm64:ilp32: change COMPAT_ELF_PLATFORM to report a a subplatform for ILP32 |
| Message-ID | <qqwRH-3eC-1@gated-at.bofh.it> |
From: Philipp Tomsich <philipp.tomsich@theobroma-systems.com>
To make life for tools (such as gdb) easier when dealing with ILP32 processes,
we report a proper subarchitecture for ILP32 in the ELF auxiliary vectors.
