Damien George 51dca54cd0 py/mkrules.mk: Remove obsolete rules for auto qstr generation. 2016-04-22 11:36:19 +01:00
Paul Sokolovsky 1b60a6dc4e py: Divide "split" and "cat" phases of qstr extraction for better efficiency.
E.g. for stmhal, accumulated preprocessed output may grow large due to
bloated vendor headers, and then reprocessing tens of megabytes on each
build make take couple of seconds on fast hardware (=> potentially dozens
of seconds on slow hardware). So instead, split once after each change,
and only cat repetitively (guaranteed to be fast, as there're thousands
of lines involved at most).

Paul Sokolovsky 21ab304c41 py/mkrules.mk: Cleanup command passed to shell. 2016-04-19 12:28:30 +03:00
Paul Sokolovsky 0dc85c9f86 py/mkrules.mk: Try to detect and emulate make -B behavior for qstr extraction.
If make -B is run, the rule is run with $? empty. Extract fron all file in
this case. But this gets fragile, really "make clean" should be used instead
with such build complexity.

Paul Sokolovsky c618f91e22 py: Rework QSTR extraction to work in simple and obvious way.
When there're C files to be (re)compiled, they're all passed first to
preprocessor. QSTR references are extracted from preprocessed output and
split per original C file. Then all available qstr files (including those
generated previously) are catenated together. Only if the resulting content
has changed, the output file is written (causing almost global rebuild
to pick up potentially renumbered qstr's). Otherwise, it's not updated
to not cause spurious rebuilds. Related make rules are split to minimize
amount of commands executed in the interim case (when some C files were
updated, but no qstrs were changed).

Jan Čapek 53e3770b15 py/mkrules.mk: Suppress line-no output from CPP for qstr auto-gen. 2016-04-16 13:19:35 +01:00
Jan Čapek 61b560f63f py/mkrules.mk: Add mpconfig[port].h dependency to qstr generating rule. 2016-04-16 13:18:51 +01:00
Jan Čapek d76c65f599 py: Add rules for automated extraction of qstrs from sources.
- add template rule that converts a specified source file into a qstring file

- add special rule for generating a central header that contains all
  extracted/autogenerated strings - defined by QSTR_DEFS_COLLECTED
  variable. Each platform appends a list of sources that may contain
  qstrings into a new build variable: SRC_QSTR. Any autogenerated
  prerequisities are should be appened to SRC_QSTR_AUTO_DEPS variable.

- remove most qstrings from py/qstrdefs, keep only qstrings that
  contain special characters - these cannot be easily detected in the
  sources without additional annotations

- remove most manual qstrdefs, use qstrdef autogen for: py, cc3200,
  stmhal, teensy, unix, windows, pic16bit:

   - remove all micropython generic qstrdefs except for the special strings that contain special characters (e.g. /,+,<,> etc.)
   - remove all port specific qstrdefs except for special strings
   - append sources for qstr generation in platform makefiles (SRC_QSTR)

Paul Sokolovsky 645045a799 py/mkrules.mk: Don't pass COPT to linker.
Oftentimes, libc, libm, etc. don't come compiled with CPU compressed code
option (Thumb, MIPS16, etc.), but we may still want to use such compressed
code for MicroPython itself.

Paul Sokolovsky 0dbd928cee Makefiles: Remove duplicate object files when linking.
Scenario: module1 depends on some common file from lib/, so specifies it
in its SRC_MOD, and the same situation with module2, then common file
from lib/ eventually ends up listed twice in $(OBJ), which leads to link
errors.

Make is equipped to deal with such situation easily, quoting the manual:
"The value of $^ omits duplicate prerequisites, while $+ retains them and
preserves their order." So, just use $^ consistently in all link targets.

Paul Sokolovsky 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.

Damien George 65dc960e3b unix-cpy: Remove unix-cpy. It's no longer needed.
unix-cpy was originally written to get semantic equivalent with CPython
without writing functional tests.  When writing the initial
implementation of uPy it was a long way between lexer and functional
tests, so the half-way test was to make sure that the bytecode was
correct.  The idea was that if the uPy bytecode matched CPython 1-1 then
uPy would be proper Python if the bytecodes acted correctly.  And having
matching bytecode meant that it was less likely to miss some deep
subtlety in the Python semantics that would require an architectural
change later on.

But that is all history and it no longer makes sense to retain the
ability to output CPython bytecode, because:

1. It outputs CPython 3.3 compatible bytecode.  CPython's bytecode
changes from version to version, and seems to have changed quite a bit
in 3.5.  There's no point in changing the bytecode output to match
CPython anymore.

2. uPy and CPy do different optimisations to the bytecode which makes it
harder to match.

3. The bytecode tests are not run.  They were never part of Travis and
are not run locally anymore.

4. The EMIT_CPYTHON option needs a lot of extra source code which adds
heaps of noise, especially in compile.c.

5. Now that there is an extensive test suite (which tests functionality)
there is no need to match the bytecode.  Some very subtle behaviour is
tested with the test suite and passing these tests is a much better
way to stay Python-language compliant, rather than trying to match
CPy bytecode.

Paul Sokolovsky cd87d20f46 mkrules.mk: Add comment why dependency parsing regex was tweaked.
(Windows compatibility.)

Ari Suutari c097ea5dd2 Adjust sed regex that processes dependency file from compiler
so that resulting file is correct also on windows systems (ie.
with file names containing drive letter).

Damien George 95f53461c2 py: Replace py-version.sh with makeversionhdr.py, written in Python.
Also rename py-version.h to mpversion.h for consistency with mpconfig.h.

Sven Wegener b98c162c52 py: Fix order-only dependencies in mkrules.mk and py.mk.
Currently compilation sporadically fails, because the automatic
dependency gets created *during* the compilation of objects.

OBJ is a auperset of PY_O and the dependencies apply to all objects.

Damien George 7a37f647a5 Merge branch 'teensy-new' of github.com:dhylands/micropython into dhylands-teensy-new
Conflicts:
	stmhal/pin_named_pins.c
	stmhal/readline.c

Renamed HAL_H to MICROPY_HAL_H.  Made stmhal/mphal.h which intends to
define the generic Micro Python HAL, which in stmhal sits above the ST
HAL.

Paul Sokolovsky 4c4b9d15ab mkrules.mk: Pass $(COPT) to link stage.
In generalize case, optimization options should be passed to all stages of
the build process.

Paul Sokolovsky 0fc7efb663 makefile: Pass STRIPFLAGS_EXTRA to strip.
Expected to be set on command line, with the idea being that for different
targets, there're different smartass ABIs which strive to put unneeded
sections into executables, etc., so let people have flexible way to
strip that.

The option name is similar to previously introduced CLFAGS_EXTRA &
LDFLAGS_EXTRA.

Damien George d553be5982 build: Simplify build directory layout by putting all headers in genhdr.
Any generated headers go in $(BUILD)/genhdr/, and are #included as

Andrew Scheller 70a7d7a943 build directory can now be renamed
The autogenerated header files have been moved about, and an extra
include dir has been added, which means you can give a custom
BUILD=newbuilddir option to make, and everything "just works"

Also tidied up the way the different Makefiles build their include-
directory flags
