preserves SEH information from C object files by copying the <code>.pdata</code>
  and <code>.xdata</code> sections into the final binary.
  This helps with debugging and profiling binaries using native tools, such as WinDbg.
  Note that until now, C functions' SEH exception handlers were not being honored,
  so this change may cause some programs to behave differently.

Instructions, registers, and assembler directives are always in UPPER CASE to remind you
that assembly programming is a fraught endeavor.
(Exception: the <code>g</code> register renaming on ARM.)

In Go object files and binaries, the full name of a symbol is the
package path followed by a period and the symbol name:
<code>fmt.Printf</code> or <code>math/rand.Int</code>.
Because the assembler's parser treats period and slash as punctuation,
