From 1290355f5ad38d174abca256d2f55c7b1c09912e Mon Sep 17 00:00:00 2001 From: Petr Hosek Date: Tue, 20 Sep 2016 20:21:13 +0000 Subject: Mark ELF sections whose name start with .note as note Previously, such section would be marked as SHT_PROGBITS which makes it impossible to use an initialized C variable declaration to emit an (allocated) ELF note. The new behavior is also consistent with ELF assembly parser.
