It costs 1188 bytes of code on Thumb 2 archs.

bare-arm: Disable enumerate and reversed builtins to make port more bare.2015-08-02T19:55:37+00:00Damien Georgedamien.p.george@gmail.com2015-08-02T19:55:37+00:00urn:sha1:1934dca6deceb8f05843173e362178700e811133py: Make qstr hash size configurable, defaults to 2 bytes.2015-07-20T11:03:13+00:00Damien Georgedamien.p.george@gmail.com2015-07-20T11:03:13+00:00urn:sha1:c3bd9415cc8e6ba3619fe4b7a2bdac20260b0236
This patch makes configurable, via MICROPY_QSTR_BYTES_IN_HASH, the
number of bytes used for a qstr hash. It was originally fixed at 2
bytes, and now defaults to 2 bytes. Setting it to 1 byte will save
ROM and RAM at a small expense of hash collisions.
py: Use a wrapper to explicitly check self argument of builtin methods.2015-06-20T15:39:39+00:00Damien Georgedamien.p.george@gmail.com2015-06-19T12:49:10+00:00urn:sha1:06593fb0f23dfc12f482561fbec1717dca0d4db4
Previous to this patch a call such as list.append(1, 2) would lead to a
seg fault. This is because list.append is a builtin method and the first
argument to such methods is always assumed to have the correct type.
Now, when a builtin method is extracted like this it is wrapped in a
checker object which checks the the type of the first argument before
calling the builtin function.
This feature is contrelled by MICROPY_BUILTIN_METHOD_CHECK_SELF_ARG and
is enabled by default.
See issue #1216.
py: Add attrtuple object, for space-efficient tuples with attr access.2015-04-21T14:14:24+00:00Damien Georgedamien.p.george@gmail.com2015-04-21T14:14:24+00:00urn:sha1:5aa311d33084c24262780cae0a65d748990ce7e1
If you need the functionality of a namedtuple but will only make 1 or a
few instances, then use an attrtuple instead.
py: Add MICROPY_COMP_{DOUBLE,TRIPLE}_TUPLE_ASSIGN config options.2015-03-14T13:11:35+00:00Damien Georgedamien.p.george@gmail.com2015-03-14T13:11:35+00:00urn:sha1:42e0c593084784cb0b630d99b8361bc88abadb78
These allow to fine-tune the compiler to select whether it optimises
tuple assignments of the form a, b = c, d and a, b, c = d, e, f.
Sensible defaults are provided.
py: Add config option MICROPY_COMP_MODULE_CONST for module consts.2015-01-10T14:07:24+00:00Damien Georgedamien.p.george@gmail.com2015-01-10T14:07:24+00:00urn:sha1:ddd1e188011a021537c87c75f0a9e1818e335d5d
Compiler optimises lookup of module.CONST when enabled (an existing
feature). Disabled by default; enabled for unix, windows, stmhal.
Costs about 100 bytes ROM on stmhal.
ports: Define mp_off_t.2014-11-16T22:16:14+00:00Paul Sokolovskypfalcon@users.sourceforge.net2014-11-16T22:16:14+00:00urn:sha1:91386eee2613cbaf736d746cfef28674cce82c01py: Use shorter, static error msgs when ERROR_REPORTING_TERSE enabled.2014-11-06T17:36:16+00:00Damien Georgedamien.p.george@gmail.com2014-11-06T17:36:16+00:00urn:sha1:1e9a92f84fb58db610e20b766052292edc28d25b
Going from MICROPY_ERROR_REPORTING_NORMAL to
MICROPY_ERROR_REPORTING_TERSE now saves 2020 bytes ROM for ARM Thumb2,
and 2200 bytes ROM for 32-bit x86.
This is about a 2.5% code size reduction for bare-arm.
