[Qemu-devel] [PATCH v8 82/87] linux-user: Add support for nanoMIPS core


From: Aleksandar Markovic
Subject: [Qemu-devel] [PATCH v8 82/87] linux-user: Add support for nanoMIPS core files
Date: Mon, 13 Aug 2018 19:53:47 +0200

From: Aleksandar Rikalo <address@hidden>

nanoMIPs core files require value EF_NANOMIPS_ABI_P32 to be passed
to the e_flags part of the core's elf header.
