[PATCH 02/18] perf annotate: Don't truncate Intel style addresses

From: Arnaldo Carvalho de Melo
Date: Fri Aug 15 2014 - 12:50:33 EST


From: Alex Converse <aconverse@xxxxxxxxxx>

Instructions like "mov r9,QWORD PTR [rdx+0x8]" were being truncated to
"mov r9,QWORD" by code that assuemd operands cannot have spaces.
