There were several different spellings of MicroPython present in comments,
when there should be only one.
py/compile: Combine arith and bit-shift ops into 1 compile routine.2017-07-05T05:49:00+00:00Krzysztof Blazewiczblazewicz.krzysztof@gmail.com2017-04-27T19:32:50+00:00urn:sha1:a040fb89e7b8507aa775b0620de1770642b0f5ee
This refactoring saves code space.
py/compile: Refactor handling of special super() call.2017-04-22T11:46:32+00:00Damien Georgedamien.p.george@gmail.com2017-04-18T12:52:18+00:00urn:sha1:5335942b599d85263d3c18eb99ff5ebd04a8bc98
This patch refactors the handling of the special super() call within the
compiler. It removes the need for a global (to the compiler) state variable
which keeps track of whether the subject of an expression is super. The
handling of super() is now done entirely within one function, which makes
the compiler a bit cleaner and allows to easily add more optimisations to
super calls.
Changes to the code size are:
bare-arm: +12

py/grammar: Remove unused rule.2017-02-17T01:48:45+00:00Damien Georgedamien.p.george@gmail.com2017-02-17T01:48:45+00:00urn:sha1:bdebfaa4bf422ef164fa78257b59415e5dffc6cb
Since the recent changes to string/bytes literal concatenation, this rule
is no longer used.
py: Do adjacent str/bytes literal concatenation in lexer, not compiler.2017-02-17T01:12:40+00:00Damien Georgedamien.p.george@gmail.com2017-02-17T01:12:40+00:00urn:sha1:534b7c368dc2af7720f3aaed0c936ef46d773957
It's much more efficient in RAM and code size to do implicit literal string
concatenation in the lexer, as opposed to the compiler.
RAM usage is reduced because the concatenation can be done right away in the
tokeniser by just accumulating the string/bytes literals into the lexer's
vstr. Prior to this patch adjacent strings/bytes would create a parse tree
(one node per string/bytes) and then in the compiler a whole new chunk of
memory was allocated to store the concatenated string, which used more than
double the memory compared to just accumulating in the lexer.
This patch also significantly reduces code size:
bare-arm: -204
minimal: -204
unix x64: -328
stmhal: -208
esp8266: -284
cc3200: -224
