# * 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.
|
|
# * no-vectorize-loops turns off the loop vectorizer (seeing as the M0+ doesn't
|
|
# have SIMD)
