* 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)
- 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
The IAR assembler doesn't accept '--preinclude', but it accepts -D.
This commit changes the way the config-related macros are propagated
to the IAR assembler to use '-D' instead of '--preinclude'. This is
the only change related to functionality, the others are small,
backward compatible changes to the config code to make passing arguments
to the toolchain instances easier.
Tested by compiled blinky with IAR, GCC_ARM and ARM for K64F.
IAR defaults to C99 mode, but doesn't enable VLAs by default. Enable them
to make it more conformant.
We don't have much if any code using actual variable-length arrays, but
variably-modified types are occasionally used. The same switch controls
both.
(VLAs were actually already enabled in most of the project export
templates, but not the build script).
This commit uses the previously introduced feature of generating
configuration data as a C header file rather than as command line macro
definitions. Each toolchain was modified to use prefix headers if
requested, and build_api.py was modified to set up the toolchain's
prefix header content using the data generated by the config system.
Tested by compiling blinky for GCC and ARMCC. I'm having a few issues
with my IAR license currently, but both ARMCC and IAR use the same
`--preinclude` option for prefix headers, so this shouldn't be an issue.
Note that at the moment all exporters still use the previous
configuration data mechanism (individual macro definitions as opposed to
a prefix header). Exporters will be updated in one or more PRs that will
follow.
- vla flag is not compatible with c++ (not supported), it generates an error
in the IDE. Therefore we remove it
- common flags - add dlib and thum to the common flags.
- cpu flag is for only runtime cmd, IDE sets it via defined MCU, not required.
