Add the locks and flags necessary to make the IAR standard library
thread safe. These changes consist of:
-Add compiler flag "--guard_calls" to ensure C++ function-static
variables with dynamic initializers are initialized in a
thread safe manner
-Add the linker flag "--threaded_lib" so the thread safe version of
the standard library is used
-Implement mutex functions required for IAR thread safety
-Create a set of stub functions in retarget.c for when the rtos is not present
targets.py : add IAR for NUCLEO_F746ZG and DISCO_F746NG
iar.py: in case of Cortex-M7F, change it into Cortex-M7 and add --fpu
VFPv5_sp
I have been confirmed that for Cortex-M4F we don't need to add the --fpu
VFPv4_sp
Now implemented as a 'post binary hook'. Targets that need this will have
to inherit from LPCTarget instead of Target, the rest should be automatic
(but see LPC4088 for an exception (currently, hooks can't be chained
automatically))
- restored assemble/compile_c/compile_cpp, except now they return the commands
that will run, instead of actually running the commands
- remove need_update_new, since it doesn't seem to be used anywhere
Support multiple commands per compile
Reuse _assemble() and _compile() for sequential and parallel compiles
Preserve compile(), compile_c(), compile_cpp() and assemble() methods functionality
compiler, linker, assembler and binary command lines can now be modified
using the hooks mechanism. Also, '--any_placement=first_fit' linker option
is now used only on LPC4088 using this mechanism, in order to preserve
compatibility with the other targets.
Updated CMSIS DSP to latest version (CMSIS-SP-00300-r3p2-00rel1.zip)
Build system changes to be able to preprocess assembler sources before compiling them:
- GCC: use gcc '-x assembler-with-cpp'
- ARM: preprocess first, then assemble (two separate commands)
- IAR: added macro definitions and include directories to the assembler command line
Removed CORTEX_ARM_SUPPORT restriction for the DSP libraries.
Tested: LPC1768 with ARM, GCC_ARM and IAR, LPC11U24 with ARM.
build_api.py now support macros defined at compile time, so build.py and
make.py can be used like this:
$ make.py/build.py <options> -DMACRO1 -DMACRO2=VALUE2 ...
Initial support (activate with "-o analyze"). Not working well with IAR
for now (partially because of a bug in goannac++ which was reported to
Red Lizzard).
