Damien George	06659077a8	all: Update Python code to conform to latest black formatting. ... Updating to Black v20.8b1 there are two changes that affect the code in this repository: - If there is a trailing comma in a list (eg [], () or function call) then that list is now written out with one line per element. So remove such trailing commas where the list should stay on one line. - Spaces at the start of """ doc strings are removed.

Damien George	69661f3343	all: Reformat C and Python source code with tools/codeformat.py. ... This is run with uncrustify 0.70.1, and black 19.10b0.	2020-02-28 10:33:03 +11:00
Damien George	0bd7d1f7f0	py/persistentcode: Move loading of rodata/bss to before obj/raw-code. ... This makes the loading of viper-code-with-relocations a bit neater and easier to understand, by treating the rodata/bss like a special object to be loaded into the constant table (which is how it behaves).	2019-12-17 13:22:11 +11:00
Damien George	abc642973d	py/dynruntime: Add support for float API to make/get floats. ... We don't want to add a feature flag to .mpy files that indicate float support because it will get complex and difficult to use. Instead the .mpy is built using whatever precision it chooses (float or double) and the native glue API will convert between this choice and what the host runtime actually uses.	2019-12-12 20:15:28 +11:00
Damien George	aad79adab7	tools/mpy_ld.py: Add new mpy_ld.py tool and associated build files. ... This commit adds a new tool called mpy_ld.py which is essentially a linker that builds .mpy files directly from .o files. A new header file (dynruntime.h) and makefile fragment (dynruntime.mk) are also included which allow building .mpy files from C source code. Such .mpy files can then be dynamically imported as though they were a normal Python module, even though they are implemented in C. Converting .o files directly (rather than pre-linked .elf files) allows the resulting .mpy to be more efficient because it has more control over the relocations; for example it can skip PLT indirection. Doing it this way also allows supporting more architectures, such as Xtensa which has specific needs for position-independent code and the GOT. The tool supports targets of x86, x86-64, ARM Thumb and Xtensa (windowed and non-windowed). BSS, text and rodata sections are supported, with relocations to all internal sections and symbols, as well as relocations to some external symbols (defined by dynruntime.h), and linking of qstrs.	2019-12-12 20:15:28 +11:00
