So, now each port should call mp_stack_ctrl_init() on its own, ASAP after startup, and taking special precautions so it really was called before stack variables get allocated (because if such variable with a pointer is missed, it may lead to over-collecting (typical symptom is segfaulting)). py: Change type signature of builtin funs that take variable or kw args. 2016-01-11T00:49:27+00:00 Damien George damien.p.george@gmail.com 2016-01-03T14:21:40+00:00 urn:sha1:4b72b3a133ea87a1ef8b964508dc25c551ccf093 With this patch the n_args parameter is changed type from mp_uint_t to size_t. py: Change struct and macro for builtin fun so they can be type checked. 2016-01-03T11:53:44+00:00 Damien George damien.p.george@gmail.com 2016-01-03T11:53:44+00:00 urn:sha1:1b0aab621baf081bf1cbeb38a29bd37fbc135cc7 py: Allocate parse nodes in chunks to reduce fragmentation and RAM use. 2015-10-01T23:11:11+00:00 Damien George damien.p.george@gmail.com 2015-09-23T09:50:43+00:00 urn:sha1:58e0f4ac50b3dc732cbfe0d7b04bb41951ac1329 With this patch parse nodes are allocated sequentially in chunks. This reduces fragmentation of the heap and prevents waste at the end of individually allocated parse nodes. Saves roughly 20% of RAM during parse stage. bare-arm, minimal, qemu-arm: Make do_str() take parse-input-kind as arg. 2015-06-22T21:38:47+00:00 Damien George damien.p.george@gmail.com 2015-06-22T21:38:47+00:00 urn:sha1:c4b592d3793bae6effe13a9b606083c9097d2779 The do_str() function is provided essentially as documentation to show how to compile and execute a string. This patch makes do_str take an extra arg to specify how the string should be interpreted: either as a single line (ie from a REPL) or as multiple lines (ie from a file). qemu-arm: Get compiling again with recent changes to print framework. 2015-04-16T20:44:52+00:00 Damien George damien.p.george@gmail.com 2015-04-16T20:44:52+00:00 urn:sha1:2941d5c714fc7e5ada791b52f712f758ec120fa0 py: Overhaul and simplify printf/pfenv mechanism. 2015-04-16T14:30:16+00:00 Damien George damien.p.george@gmail.com 2015-04-09T22:56:15+00:00 urn:sha1:7f9d1d6ab923096582622b700bedb6a571518eac Previous to this patch the printing mechanism was a bit of a tangled mess. This patch attempts to consolidate printing into one interface. All (non-debug) printing now uses the mp_print* family of functions, mainly mp_printf. All these functions take an mp_print_t structure as their first argument, and this structure defines the printing backend through the "print_strn" function of said structure. Printing from the uPy core can reach the platform-defined print code via two paths: either through mp_sys_stdout_obj (defined pert port) in conjunction with mp_stream_write; or through the mp_plat_print structure which uses the MP_PLAT_PRINT_STRN macro to define how string are printed on the platform. The former is only used when MICROPY_PY_IO is defined. With this new scheme printing is generally more efficient (less layers to go through, less arguments to pass), and, given an mp_print_t* structure, one can call mp_print_str for efficiency instead of mp_printf("%s", ...). Code size is also reduced by around 200 bytes on Thumb2 archs.
