* added/improved global chroot support
* added RESPONSE_FILES flag to support optional response files (on linux the cmd param length is 2 megabytes). Default True
* added unified handling for archive and link response file (similar to includes)
* added COMPILE_C_AS_CPP flag to support compiling of c files as cpp. Default False
* added mbedToolchain.init() for post __init__ hooks
* added caching to mbedToolchain.need_update() to reduce IO hits
* added support to identify compiler warning/error column (supports ARMCC, GCC and IAR). Errors/warnings now report file@line,col
* added global TOOLCHAIN_PATHS which allows overriding/changing of the toolchain paths. Also simplified ARM-related paths
* added target.json to mbed library release (by @0xc0170)* migrated compile_worker() to utils.py for lightweight thread initialization
* improved run_cmd() performance by removing unnecessary check about the command being executed (should be checked once in the relevant toolchain instead)
* removed remnants of Goanna support (should be reimplemented as hooks to compile/link/archive instead)
* fixes for Python 2.7 compatibility (by @0xc0170)
* fixes for Exporters (by @0xc0170)
This commit includes
- Changing build option parameter from -O2 to -Os to reduce flash size of the
final binary pacakge.
The original parameter of -O2 is kept to circumvent the error
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46762 .
But this error has been long fixed and released in latest 4.9.x GCC compiler.
This change is necessary to reduce the generated binary size of mbed Client component to
avoid problem of getting images over 512 kB which is causing application to crash because of
Configuration Store problem https://github.com/ARMmbed/configuration-store/issues/21
It's nicer to be compatible with the standards.
I have added one more field to the description of each function:
Side effects. This feild contains the expected side effects of
running a particular method. If the side effects of a method are
None, it is expected that the function does not change anything in
any envoronment and that running it multiple times with the same
arguments will produce the same result every time. That is when
Side effects is non, the method is expected to be pure.
The methods themselfes do nothing within the abstract base class
mbedToolchain. This change enforces that toolchains do not call
these methods that contain no implementation.
The test simply tries to instantiate each class exposed as part of the
TOOLCHAIN_CLASSES map. This is a test that each toolchain class
implements the required API, as the mbedToolchain will not allow the
instantiation of a subclass without a part of that API.
The mbedToolchain class calls many members of it's subclasses, expecting
them to implement a particular API. This change adds a requirement to
each subclass that requires them to implement this expected API.
The API consists of these methods:
- parse_dependencies
- parse_ouptut
- get_config_option
- compile_c
- compile_cpp
- link
- archive
- binary
This commit adds a check for configuration data changes. If a change in
configuration data is detected, all the sources in the tree are rebuilt.
This is a fix for #2073. #2162 was originally proposed as a fix, but it
was agreed that `--preinclude` is a more convenient way to include
configuration data, since it can be used to change the behaviour of
source files that don't include "mbed_config.h" directly, which is a big
advantage when importing 3rd party source trees. Compared to #2162, this
commit has the disadvantage of rebuilding all the source files if a
configuration change is detected, but it was agreed that the advantage
of using `--preinclude` outweighs the disadvantage of the increased
compilation time.
Remove special case targets which have floating point enabled in
Newlib Nano from gcc.py. To enable floating point printf/scanf
for a target configure it to use the 'standard' default build in
targets.json rather than 'small'.
This commit adds information about the location of problematic JSON
files when reporting a JSON parsing error.
Before this commit:
```
[ERROR] Expecting property name: line 7 column 9 (char 188)
```
After this commit:
```
Error parsing 'core/mbed_lib.json':
[ERROR] Expecting property name: line 7 column 9 (char 188)
```
Previously, add_py_targets assumed that it is not an error to add an
existing target if that target was previously added using
add_py_targets. This was done to aid testing, but it was weird, error
prone and broke with the latest changes to the caching mechanism. With
this commit:
- it is always an error to add a target that was previously added, which
is much more consistent.
- tests for the configuration mechanism use the newly added
'set_targets_json_location' function to clear the internal caches in
targets.py (and thus all previously added custom targets). As a side
effect, this commit also tests the 'set_targets_json_location'
function itself.
With this change, it becomes possible to use targets.py with any
targets.json, not just the default one in ../hal/targets.json.
targets.py will still be initialized with the default targets.json, but
the code can then call "set_targets_json_location" to specify the new
location of targets.json. set_targets_json_location modifies all the
data "in place"; that is, it doesn't create a new TARGET_MAP,
TARGET_NAMES or alike, but rather modified the existing ones. This is
important, because code using this construct:
from tools.targets import TARGET_MAP
can work unmodified with this change.
Now funnctions are looked up in the cache using a (function name,
arguments) key, which makes it possible to cache different invocations
of the functions (with different arguments).
Also applied the @cached attribute to get_target.
There are two shell-like things that we care about
bash: does environment varible expansion with $
batch: does environment varible expansion by surrounding something with %
so to detect batch, try to expand a variable on the shell with $.
If you get a $ back, you are in batch!
when in target.json "default_build": "small" is configured
- build.py+make.py
- uses linker option --specs=nano.specs
- macro MBED_RTOS_SINGLE_THREAD is defined
- exporting with project.py + make Makefile
- doesn't use the linker option --specs=nano.specs
- doesn't contain macro MBED_RTOS_SINGLE_THREAD
With this patch in place, tests.py uses targets names instead of target
instances, which makes it possible to use application defined targets
with tests.
With this change, custom targets defined by the application being
tested in its mbed_app.json file can be used with tests. Note that
`build_project` already accepts both target names and instances, so the
call to `build_project` inside `build_tests` will still work.
The configuration object is now created early in the build_project
function. This way, if there's a mbed_app.json that contains a custom
target, that target is taken into account. This is useful (for example)
when compiling tests for an application that defines a custom target.
- removing redundancy as discussed in PR #2087:
- in target.json the core option can have only this values : "Cortex-M0", "Cortex-M0+", "Cortex-M1", "Cortex-M3", "Cortex-M4", "Cortex-M7", "Cortex-A9" - Cortex-M4F and Cortex-M7F removed
- in target.json an additional fpu option with values: "single" and "double" can be used
- build and export scripts are changed to handle this
- tested (compiling, running on hardware) with nucleo_f767 (cortex-m7 with double precision fpu), nucleo_f746 (cortex-m7 with single precision fpu), nucleo_f446 and nucleo_l467 (cortex-m4 with single precision fpu), teensy31 (cortex-m4 without fpu - only build test), nucleo_l073 (cortex-m0)
- singletest results are added to PR #2087 comments
- creating new core name Cortex_M7F_DP for a target with a double precision fpu
- adding new core name to arm.py to set compiler/linker flags to a double precision fpu when configured in target.json
- up to now: gcc wrote flag for a double precision fpu -> target with STM32F746 didn't run when using double variables - mcu has only single precision fpu
- changing gcc.py to use single precision for Cortex-M7 und double precision for Cortex_M7F_DP
tested with NUCLEO_F746, NUCLEO_F767 and build.py+make.py and exporting with project.py + compiling/flashing
- iar.py need a similar extention - I didn't change that yet because
- did not run at the moment - python exception
- currently worked on in PR #1948
