MICROPY_ENABLE_COMPILER can be used to enable/disable the entire compiler,
which is useful when only loading of pre-compiled bytecode is supported.
It is enabled by default.
MICROPY_PY_BUILTINS_EVAL_EXEC controls support of eval and exec builtin
functions. By default they are only included if MICROPY_ENABLE_COMPILER
is enabled.
Disabling both options saves about 40k of code size on 32-bit x86.
py/parse: Replace mp_int_t/mp_uint_t with size_t etc, where appropriate.2015-12-17T13:06:05+00:00Damien Georgedamien.p.george@gmail.com2015-12-17T13:06:05+00:00urn:sha1:16a6a47a7bda60704a34290bc77768bfde0d41cepy: Add support for 64-bit NaN-boxing object model, on 32-bit machine.2015-11-29T14:25:36+00:00Damien Georgedamien.p.george@gmail.com2015-11-27T17:09:11+00:00urn:sha1:b8cfb0d7b2c91ea1e17f6caeabfc9cb23166cdc1
To use, put the following in mpconfigport.h:
#define MICROPY_OBJ_REPR (MICROPY_OBJ_REPR_D)
#define MICROPY_FLOAT_IMPL (MICROPY_FLOAT_IMPL_DOUBLE)
typedef int64_t mp_int_t;
typedef uint64_t mp_uint_t;
#define UINT_FMT "%llu"
#define INT_FMT "%lld"
Currently does not work with native emitter enabled.
py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.2015-11-29T14:25:35+00:00Damien Georgedamien.p.george@gmail.com2015-11-27T17:01:44+00:00urn:sha1:999cedb90ff0827cdb9dfe0e4faa6ebc1739d271
This allows the mp_obj_t type to be configured to something other than a
pointer-sized primitive type.
This patch also includes additional changes to allow the code to compile
when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of
mp_uint_t, and various casts.

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.
py/parse: Factor logic when creating parse node from and-rule.2015-10-08T22:13:18+00:00Damien Georgedamien.p.george@gmail.com2015-10-08T22:13:18+00:00urn:sha1:366239b8b9a2fbea3b6eae8dfc7b4a503d427e4cpy: Allocate parse nodes in chunks to reduce fragmentation and RAM use.2015-10-01T23:11:11+00:00Damien Georgedamien.p.george@gmail.com2015-09-23T09:50:43+00:00urn: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.
