So this patch introduces the config option MICROPY_PY_MICROPYTHON_STACK_USE which can be used to independently control the inclusion of stack_use(). By default it is enabled if MICROPY_PY_MICROPYTHON_MEM_INFO is enabled (thus not changing any of the existing ports). 2017-12-11T02:49:09+00:00 Damien George damien.p.george@gmail.com 2017-11-26T12:28:40+00:00 urn:sha1:02d830c035aca166d70551e485ccd2d1658189c9 This patch introduces the MICROPY_ENABLE_PYSTACK option (disabled by default) which enables a "Python stack" that allows to allocate and free memory in a scoped, or Last-In-First-Out (LIFO) way, similar to alloca(). A new memory allocation API is introduced along with this Py-stack. It includes both "local" and "nonlocal" LIFO allocation. Local allocation is intended to be equivalent to using alloca(), whereby the same function must free the memory. Nonlocal allocation is where another function may free the memory, so long as it's still LIFO. Follow-up patches will convert all uses of alloca() and VLA to the new scoped allocation API. The old behaviour (using alloca()) will still be available, but when MICROPY_ENABLE_PYSTACK is enabled then alloca() is no longer required or used. The benefits of enabling this option are (or will be once subsequent patches are made to convert alloca()/VLA): - Toolchains without alloca() can use this feature to obtain correct and efficient scoped memory allocation (compared to using the heap instead of alloca(), which is slower). - Even if alloca() is available, enabling the Py-stack gives slightly more efficient use of stack space when calling nested Python functions, due to the way that compilers implement alloca(). - Enabling the Py-stack with the stackless mode allows for even more efficient stack usage, as well as retaining high performance (because the heap is no longer used to build and destroy stackless code states). - With Py-stack and stackless enabled, Python-calling-Python is no longer recursive in the C mp_execute_bytecode function. The micropython.pystack_use() function is included to measure usage of the Python stack. 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. 2017-07-31T08:35:40+00:00 Alexander Steffen devel.20.webmeister@spamgourmet.com 2017-06-30T07:22:17+00:00 urn:sha1:55f33240f3d7051d4213629e92437a36f1fac50e There were several different spellings of MicroPython present in comments, when there should be only one. 2017-07-18T12:30:22+00:00 Damien George damien.p.george@gmail.com 2017-07-18T12:30:22+00:00 urn:sha1:cadbd7f3e62488fb3c62cd35f53530e8fdb8cfea Without this cast the print will give a wrong result on nan-boxing builds. 2017-04-18T07:24:30+00:00 Damien George damien.p.george@gmail.com 2017-04-10T07:19:36+00:00 urn:sha1:bbb4b9822f094825d7e7fd1f7df716adc2598685 It controls the character that's used to (asynchronously) raise a KeyboardInterrupt exception.
