### Compiler configuration
|

|
|
# A weird behaviour of GCC garbage collector has been observed, where
|
|
# unitialized global variables with global linkage (aka non-static) put in the
|
|
# COMMON section weren't analyzed by the garbage collector at all. No idea why.
|
|
# The solution is to disable the common section, which subsequently places all
|
|
# unitialized global variables with global linkage in the .bss section,
|
|
# allowing the GC to analyze the variables. This is especially an issue with
|
|
# Board.h files, as they rely heavily on global variables placed in COMMON to
|
|
# be garbage collected if unused.
