/* # Developer notes
|
||||
|
||||
- Symbols that start with a double underscore (__) are considered "private"
|
||||
|
||||
- Symbols that start with a single underscore (_) are considered "semi-public"; they can be
|
||||
overridden in a user linker script, but should not be referred from user code (e.g. `extern "C" {
|
||||
static mut _heap_size }`).
|
||||
|
||||
- `EXTERN` forces the linker to keep a symbol in the final binary. We use this to make sure a
|
||||
symbol is not dropped if it appears in or near the front of the linker arguments and "it's not
|
||||
needed" by any of the preceding objects (linker arguments)
|
||||
|
||||
- `PROVIDE` is used to provide default values that can be overridden by a user linker script
|
||||
|
||||
- On alignment: it's important for correctness that the VMA boundaries of both .bss and .data *and*
|
||||
the LMA of .data are all `32`-byte aligned. These alignments are assumed by the RAM
|
||||
initialization routine. There's also a second benefit: `32`-byte aligned boundaries
|
||||
means that you won't see "Address (..) is out of bounds" in the disassembly produced by `objdump`.
