Previous to this patch the qemu-arm tests were compiled with is_relp=true
meaning that the __repl_print__ function was called for all lines of code
in the outer scope. This is not the right behaviour for scripts that are
executed as though they were a file (eg tests).
With this fix the micropython/heapalloc_str.py test now works so it is
removed from the test blacklist.
With caching of map lookups in the bytecode, frozen bytecode can still
work but must be stored in RAM, not ROM. This patch allows mpy-tool.py to
generate code that works with this optimisation, but it's not recommended
to use it on embedded targets (because of lack of RAM).
Previous to this patch pyboard.py would open a new serial connection to
the target for each script that was run, and for any command that was run.
Apart from being inefficient, this meant that the board was soft-reset
between scripts/commands, which precludes scripts from accessing variables
set in a previous one.
This patch changes the behaviour of pyboard.py so that the connection to
the target is created only once, and it's not reset between scripts or any
command that is sent with the -c option.
To make its inclusion as frozen modules in multiple ports less magic.
Ports are just expected to symlink 2 files into their scripts/modules
subdirs.
Unix port updated to use this and in general follow frozen modules setup
tested and tried on baremetal ports, where there's "scripts" predefined
dir (overridable with FROZEN_DIR make var), and a user just drops Python
files there.
This helps to test floating point code on Cortex-M hardware.
As part of this patch the link-time-optimisation was disabled because it
wasn't compatible with software FP support. In particular, the linker
could not find the __aeabi_f2d, __aeabi_d2f etc functions even though they
were provided by lib/libm/math.c.
