+# * linker argument --nmagic turns off page alignment of sections (which saves
+#   flash space)
+# * linker argument -Tlink.x tells the linker to use link.x as the linker
+#   script. This is usually provided by the cortex-m-rt crate, and by default
+#   the version in that crate will include a file called `memory.x` which
+#   describes the particular memory layout for your specific chip. 
+# * inline-threshold=5 makes the compiler more aggressive and inlining functions
+# * no-vectorize-loops turns off the loop vectorizer (seeing as the M0+ doesn't
+#   have SIMD)
