+// This file defines delimiters for Sanitizer Coverage's section. It contains

+// arrays. According to https://msdn.microsoft.com/en-us/library/7977wcck.aspx
+// sections with the same name before "$" are sorted alphabetically by the
+// string that comes after "$" and merged into one section. We take advantage
+// of this by putting data we want the size of into the middle (M) of a section,
+// by using the letter "M" after "$". We get the start of this data (ie:
+// __start_section_name) by making the start variable come at the start of the
+// section (using the letter A after "$"). We do the same to get the end of the
+// data by using the letter "Z" after "$" to make the end variable come after
+// the data. Note that because of our technique the address of the start
+// variable is actually the address of data that comes before our middle
+// section. We also need to prevent the linker from adding any padding. Each
+// technique we use for this is explained in the comments below.
