This means that the assembler code no longer needs to know about the global state structure which makes it much easier to maintain. py/nlrthumb: Make compatible with Cortex-M0 (ARMv6M instr set). 2015-10-20T12:26:34+00:00 Damien George damien.p.george@gmail.com 2015-10-20T12:26:34+00:00 urn:sha1:22521ea9e2a83dbcbd6da16d6a76b01aa3bf039a py: Put all global state together in state structures. 2015-01-07T20:33:00+00:00 Damien George damien.p.george@gmail.com 2015-01-01T23:30:53+00:00 urn:sha1:b4b10fd350852e321624d74983cca286091b55a1 This patch consolidates all global variables in py/ core into one place, in a global structure. Root pointers are all located together to make GC tracing easier and more efficient. py: Move global variable nlr_top to one place, in a .c file. 2015-01-01T21:47:58+00:00 Damien George damien.p.george@gmail.com 2015-01-01T21:47:58+00:00 urn:sha1:8a2347723eba9899a12799021b4e47bd1fa20282 This reduces dependency on assembler, and allows to consolidate global variables in the future. py: Fix some macros defines; cleanup some includes. 2014-11-05T21:16:41+00:00 Damien George damien.p.george@gmail.com 2014-11-05T21:16:41+00:00 urn:sha1:7860c2a68acd1ccd28cb4bb87819487fd6966a9e py: Clean up nlr*.S to make it easier to read; fix clang .bss error. 2014-09-26T13:07:26+00:00 Damien George damien.p.george@gmail.com 2014-09-26T13:07:26+00:00 urn:sha1:133b083b89af1104c86ea127ad02bfb639421277 It seems that newer versions of clang don't like the .bss directive, so we don't use it for OSX. Addressing issues #865 and #875. py: Support arm and thumb ARM ISAs, in addition to thumb2. 2014-06-21T22:40:45+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-06-21T22:14:28+00:00 urn:sha1:a96cc824bdacb34ced0edef523181c215fba313b These changes were tested with QEMU, and by few people of real hardware. Add license header to (almost) all files. 2014-05-03T22:27:38+00:00 Damien George damien.p.george@gmail.com 2014-05-03T22:27:38+00:00 urn:sha1:04b9147e150d2d6fa3750f312fe328b6a71c1b28 Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/. py: If setjmp NLR implementation is forced, omit native versions. 2014-04-30T01:19:20+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-04-30T01:19:20+00:00 urn:sha1:b1ce37d32e1b77373a86d27d1f1f925891a402d1 Add a check for NULL nlr_top in nlr_jump. 2014-04-08T14:08:14+00:00 Damien George damien.p.george@gmail.com 2014-04-08T14:08:14+00:00 urn:sha1:26cf55ae05658c8a47719d46d48df8c9751108b5 If no nlr_buf has been pushed, and an nlr_jump is called, then control is transferred to nlr_jump_fail (which should bail out with a fatal error).
