22521ea9e2 py/nlrthumb: Make compatible with Cortex-M0 (ARMv6M instr set). 2015-10-20 13:26:34 +01:00

04353cc85e py: With obj repr "C", change raw str accessor from macro to function. 
This saves around 1000 bytes (Thumb2 arch) because in repr "C" it is
costly to check and extract a qstr.  So making such check/extract a
function instead of a macro saves lots of code space.

183edefddd py: Add object repr "C", where 30-bit floats are stuffed in obj word. 
This new object representation puts floats into the object word instead
of on the heap, at the expense of reducing their precision to 30 bits.
It only makes sense when the word size is 32-bits.

e0f5df579b all: Make netutils.h available to all ports by default. 
Generally, ports should inherit INC from py.mk, append to it, not
overwrite it. TODO: Likely should do the same for other vars too.

8ee153f234 unix/modtime: Implement ticks_ms(), ticks_us() and ticks_diff(). 
All of these functions return positive small int, thus range is 2 bits less
than word size (30 bit on 32-bit systems, 62 bit on 64-bit systems).

e813541e3f py: Add option for inline assembler to support ARMv7-M instructions. 
Cortex-M0, M0+ and M1 only have ARMv6-M Thumb/Thumb2 instructions.  M3,
M4 and M7 have a superset of these, named ARMv7-M.  This patch adds a
config option to enable support of the superset of instructions.

408b74d74c py: Allow to to build MicroPython as a static library. 
The whole current port gets slurped into a static lib named
"libmicropython.a". Maybe that's not ideal, but at least something
to start with.

64f2b213bb py: Move constant folding from compiler to parser. 
It makes much more sense to do constant folding in the parser while the
parse tree is being built.  This eliminates the need to create parse
nodes that will just be folded away.  The code is slightly simpler and a
bit smaller as well.

Constant folding now has a configuration option,
MICROPY_COMP_CONST_FOLDING, which is enabled by default.

91fc075a33 py/objarray: Allow to create array of void pointers, as extension to CPython. 
Using 'P' format specifier (matches struct module). This is another shortcut
for FFI, just as previously introduced "array of objects" ('O').

b948de36fb py: Don't generate unnecessary parse nodes for assignment or kwargs. 
This patch eliminates the need for a nested parse node for assignments
and keyword arguments.  It saves a little bit of RAM when parsing.

58e0f4ac50 py: Allocate parse nodes in chunks to reduce fragmentation and RAM use. 
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.

2f4e8511cd py/mpz: Force rhs of mpz_shl_inpl/mpz_shr_inpl to be unsigned. 
Python semantics are that rhs of shift must be non-negative, so there's
no need to handle negative values in the underlying mpz implementation.

5f3c3ec5e6 py/parsenum: Provide detailed error for int parsing with escaped bytes. 
This patch adds more fine grained error message control for errors when
parsing integers (now has terse, normal and detailed).  When detailed is
enabled, the error now escapes bytes when printing them so they can be
more easily seen.

9d5e5c08ab py/compile: Put compiler state on the C stack. 
It's relatively small (between 44 and 56 bytes) and helps to reduce heap
pressure and fragmentation during compilation.

fbcaf0ea18 py: Slightly simplify compile and emit of star/double-star arguments. 
Saves a few bytes of code space and eliminates need for rot_two
bytecode (hence saving RAM and execution time, by a tiny bit).

8b4fb4fe14 py/mpz: Fix calculation of max digit storage for mpz; fix sys.maxsize. 
When creating constant mpz's, the length of the mpz must be exactly how
many digits are used (not allocated) otherwise these numbers are not
compatible with dynamically allocated numbers.

Addresses issue #1448.

0af73014cc lib/mp-readline: Add auto-indent support. 
4 spaces are added at start of line to match previous indent, and if
previous line ended in colon.

Backspace deletes 4 space if only spaces begin a line.

Configurable via MICROPY_REPL_AUTO_INDENT.  Disabled by default.
