The optimization drops the untranslated strings and replaces them with a compressed_string_t struct. It can then be decompressed to a c string. Builds without LTO work as well but include both untranslated strings and compressed strings. This work could be expanded to include QSTRs and loaded strings if a compress method is added to C. Its tracked in #531. extmod/modframebuf: Add 8-bit greyscale format (GS8). 2017-12-14T06:36:13+00:00 Damien George damien.p.george@gmail.com 2017-12-14T06:36:13+00:00 urn:sha1:46b35356e1727365dd5a33fcf3a722fda82c8b08 extmod/modframebuf: Add 2-bit color format (GS2_HMSB). 2017-12-14T06:13:02+00:00 Petr Viktorin encukou@gmail.com 2017-07-15T13:53:47+00:00 urn:sha1:34247465c34113bb26f6c9582ea31f31b0ea0d1b This format is used in 2-color LED matrices and in e-ink displays like SSD1606. all: Remove inclusion of internal py header files. 2017-10-04T01:37:50+00:00 Damien George damien.p.george@gmail.com 2017-10-04T01:37:50+00:00 urn:sha1:a3dc1b1957d2c96d7c60c2c629c95077b03488a1 Header files that are considered internal to the py core and should not normally be included directly are: py/nlr.h - internal nlr configuration and declarations py/bc0.h - contains bytecode macro definitions py/runtime0.h - contains basic runtime enums Instead, the top-level header files to include are one of: py/obj.h - includes runtime0.h and defines everything to use the mp_obj_t type py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h, and defines everything to use the general runtime support functions Additional, specific headers (eg py/objlist.h) can be included if needed. all: Update Makefiles and others to build with new ports/ dir layout. 2017-09-06T04:09:13+00:00 Damien George damien.p.george@gmail.com 2017-09-06T04:09:13+00:00 urn:sha1:4a93801c12898898744131f57d79cf216d0861b3 Also renames "stmhal" to "stm32" in documentation and everywhere else. extmod: Use MP_ROM_INT for int values in an mp_rom_map_elem_t. 2017-07-31T03:00:34+00:00 Damien George damien.p.george@gmail.com 2017-07-31T03:00:34+00:00 urn:sha1:bbced3b4bbc8fd7ed7843d39143b6c600adc2c60 extmod/modframebuf: Use correct initialization for .locals_dict. 2017-07-29T07:26:41+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-07-29T07:26:41+00:00 urn:sha1:036b58228c36ea971ec80ee4df875d858eacdfb3 extmod/modframebuf: Consistently use "col" as name for colour variables. 2017-07-25T04:06:44+00:00 Damien George damien.p.george@gmail.com 2017-07-25T04:06:44+00:00 urn:sha1:f3687109d56793b73288e081a5f4ad6884ded28d Thanks to @kamikaze, aka Oleg Korsak, for the original idea and patch. extmod/modframebuf: Fix invalid stride for odd widths in GS4_HMSB fmt. 2017-07-25T02:29:02+00:00 Radomir Dopieralski openstack@sheep.art.pl 2017-07-24T10:58:30+00:00 urn:sha1:363087aa11a5121ecff38f9e3a2372a42fa224ac Since the stride is specified in pixels, in a 4-bit horizontal format it has to always be even, otherwise the computation is wrong and we can write outside of the buffer sometimes.
