commit e8b9832af19e5975fb2a9dbe729eaba0373c781f
Author: Mark Wielaard <mark@klomp.org>
Date: Mon Dec 3 00:03:39 2018 +0100
libebl: Fix reading GNU_PROPERTY_STACK_SIZE reading from 32bit notes.
When reading a GNU_PROPERTY_STACK_SIZE we need to use the proper data
type. GElf_Addr is 64bit always and when reading a 32bit size part of
it would not be initialized. Use either Elf32_Addr or Elf64_Addr to
read and print the data.
Add 32bit and 64bit, little and big endian testcases.
