Although GCC seems to be able to grok it, it looks weird
in my editor. this is the only place in the code base where
this combination is used, so I hope its okay to remove it.
The logic can be simplified by using integer logic without a functional
change. Reduces code size by 40% (78 bytes -> 46 bytes) and silences
a Warith-conversion warning.
Converting floats to doubles is very expensive on esp8266, so prefer
calculations or comparisons as float. This saves 10% (20 bytes) of the
String::parseFloat() code size and probably quite a bit of runtime
overhead.
Check that building the eboot.c block generates the same binary as
the verison checked into the repo. Catches the case where a library
or eboot.c file is changed, but an updated eboot.elf isn't included
in a PR.
Can't do simple binary diff of the ELFs because paths and compile
times will change, so dump the two sections we care about.
There is a window where the eboot sector is erased and
unwritten/partially written. If there's a power cycle at this time, the
chip will brick due to eboot being corrupted.
Avoid this by checking if the new eboot 4K sector is identical to the
one already in flash, and if so don't rewrite it.
The ROM routine __divsi3 is called by code whenever a division is needed,
because there is no divide unit on the ESP8266 core. When the divide
routine in ROM hits a div-by-zero case, it jumpt to an ILL(egal instruction)
at a fixed address which causes a HW exception 0 (IllegalInsnException).
In the postmortem dump, when an ILL exception is detected at this address
in ROM, convert it to a DivByZeroException for printout (6).
Divde by zero errors now print as follows:
````
--------------- CUT HERE FOR EXCEPTION DECODER ---------------
Exception (6):
epc1=0x4000dce5 epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000000 depc=0x00000000

And will decode as follows:
````

PC: 0x4000dce5
EXCVADDR: 0x00000000

Remove get.py percent dump to shorten PIO output 99%.
Use latest release version of PIO, not bleeding edge, to fix
failures introduced in devel (non-release) PIO versions.

* Add SerialEvent() callback to loop processing
Match the AVR SerialEvent implicit callback. Callback is executed
in normal user mode, not IRQ, so standard processing can be uses.
Fixes#752 after 5 years. :)
* Fix style
* Clean up minor warnings from LGTM.com
LGTM (Semmie) is a tool, bought by GitHub last year, that conducts basic
linting tasks on code and HTML.
Clean up the warnings identified in the latest report:
https://lgtm.com/projects/g/esp8266/Arduino/?mode=list
No functionality should change, however this may fix some issues with
the perl utilities not exiting properly on a Ctrl-C from the command
line.
* Back out HTML changes and rerun boards.txt.py
Run valgrind on host mock example runs to catch more bugs in CI. These
tests would have caught the problem in #7464 before users did.
Add a list of some randomly picked examples to run, and add an option to
run the loop exactly once in the host mock routine, so the test will
actually exit under valgrind.
Parameters that are only used in an assert() statement are unused when
the NoAssert-NDEBUG option is used. This causes the following unused
parameter warnings while building:

Mark them unused in the code to avoid the error. The assert() still
works.
