Answer 1

From Microsoft's documentation for the /MAP linker option:

A mapfile is a text file that contains the following information about the program being linked:

• The module name, which is the base name of the file
• The timestamp from the program file header (not from the file system)
• A list of groups in the program, with each group's start address (as section:offset), length, group name, and class
• A list of public symbols, with each address (as section:offset), symbol name, flat address, and .obj file where the symbol is defined
• The entry point (as section:offset)
