      py: Remove mp_load_const_bytes and instead load precreated bytes object. · 59fba2d6
      Damien George authored
      Previous to this patch each time a bytes object was referenced a new
      instance (with the same data) was created.  With this patch a single
      bytes object is created in the compiler and is loaded directly at execute
      time as a true constant (similar to loading bignum and float objects).
      This saves on allocating RAM and means that bytes objects can now be
      used when the memory manager is locked (eg in interrupts).
      
      The MP_BC_LOAD_CONST_BYTES bytecode was removed as part of this.
      
      Generated bytecode is slightly larger due to storing a pointer to the
      bytes object instead of the qstr identifier.
      
      Code size is reduced by about 60 bytes on Thumb2 architectures.

      py: Convert hash API to use MP_UNARY_OP_HASH instead of ad-hoc function. · c2a4e4ef
      Damien George authored
      Hashing is now done using mp_unary_op function with MP_UNARY_OP_HASH as
      the operator argument.  Hashing for int, str and bytes still go via
      fast-path in mp_unary_op since they are the most common objects which
      need to be hashed.
      
      This lead to quite a bit of code cleanup, and should be more efficient
      if anything.  It saves 176 bytes code space on Thumb2, and 360 bytes on
      x86.
      
      The only loss is that the error message "unhashable type" is now the
      more generic "unsupported type for __hash__".

      py: Implement full func arg passing for native emitter. · 9988618e
      Damien George authored
      This patch gets full function argument passing working with native
      emitter.  Includes named args, keyword args, default args, var args
      and var keyword args.  Fully Python compliant.
      
      It reuses the bytecode mp_setup_code_state function to do all the hard
      work.  This function is slightly adjusted to accommodate native calls,
      and the native emitter is forced a bit to emit similar prelude and
      code-info as bytecode.

      py: Parse big-int/float/imag constants directly in parser. · 7d414a1b
      Damien George authored
      Previous to this patch, a big-int, float or imag constant was interned
      (made into a qstr) and then parsed at runtime to create an object each
      time it was needed.  This is wasteful in RAM and not efficient.  Now,
      these constants are parsed straight away in the parser and turned into
      objects.  This allows constants with large numbers of digits (so
      addresses issue #1103) and takes us a step closer to #722.

      Add license header to (almost) all files. · 04b9147e
      Damien George authored
      Blanket wide to all .c and .h files.  Some files originating from ST are
      difficult to deal with (license wise) so it was left out of those.
      
      Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

      py: Remove unique_codes from emitglue.c. Replace with pointers. · df8127a1
      Damien George authored
      Attempt to address issue #386.  unique_code_id's have been removed and
      replaced with a pointer to the "raw code" information.  This pointer is
      stored in the actual byte code (aligned, so the GC can trace it), so
      that raw code (ie byte code, native code and inline assembler) is kept
      only for as long as it is needed.  In memory it's now like a tree: the
      outer module's byte code points directly to its children's raw code.  So
      when the outer code gets freed, if there are no remaining functions that
      need the raw code, then the children's code gets freed as well.
      
      This is pretty much like CPython does it, except that CPython stores
      indexes in the byte code rather than machine pointers.  These indices
      index the per-function constant table in order to find the relevant
      code.

      Rename rt_* to mp_*. · d17926db
      Damien George authored
      Mostly just a global search and replace.  Except rt_is_true which
      becomes mp_obj_is_true.
      
      Still would like to tidy up some of the names, but this will do for now.

      py: Simplify fastn in VM; reduce size of unique code struct. · d0691cca
      Damien George authored
      We still have FAST_[0,1,2] byte codes, but they now just access the
      fastn array (before they had special local variables).  It's now
      simpler, a bit faster, and uses a bit less stack space (on STM at least,
      which is most important).
      
      The only reason now to keep FAST_[0,1,2] byte codes is for compressed
      byte code size.

      Split qstr into pools, and put initial pool in ROM. · eb7bfcb2
      Damien George authored
      Qstr's are now split into a linked-list of qstr pools.  This has 2
      benefits: the first pool can be in ROM (huge benefit, since we no longer
      use RAM for the core qstrs), and subsequent pools use m_new for the next
      pool instead of m_renew (thus avoiding a huge single table for all the
      qstrs).
      
      Still would be better to use a hash table, but this scheme takes us part
      of the way (eventually convert the pools to hash tables).
      
      Also fixed bug with import.
      
      Also improved the way the module code is referenced (not magic number 1
      anymore).
