From 5bc0dc0c9d3609d16dc27f6bd4b6fea9a4e29760 Mon Sep 17 00:00:00 2001 From: Jose de Sousa Date: Thu, 12 Jun 2014 00:05:20 +0100 Subject: [PATCH] target: write gmon.out according to target endianness After profiling gmon.out was being written in little endian format only which would cause gprof to issue and error and exit on big endian targets.
