GNU ARM Eclipse plug-ins v1.1.6-201311220955 released

Posted on November 22, 2013 by Liviu Ionescu.

The main changes are the improvements done in the templates code.

New features:

separate template configurations for standalone, retargetting or semihosting
a local _sbrk() was added, to match the definitions in the linker scripts; compared to the one included in newlib, this one:
- enforces align(4) to avoid alignment problems
- checks _Heap_Limit instead of SP (RTOS can allocate it below)
the libgloss/syscalls.c was included locally, to make the semihosting implementation details explicit and to allow the separate _sbrk().

Bugs fixed:

[bugs:#66, support-requests:#30] the sections.ld _end definition is now based on _end_noinit to make the templates compile in Release
[bugs:#63] updating the toolchain settings for multiple configurations at once is now possible
[bugs:#65] when using cortex-m4 and float hard or softfp, automatically select fpv4spd16, otherwise the build failed
[support-requests:#30] the pointers used in the init_array sections are void* to avoid warnings.

Other changes:

the librdimon linker options were added to the Hello World templates, to make it compile directly
when using startup files, the DEBUG version of ResetHandler is no longer naked, to allow breakpoints
since the __register_exitproc() provided by newlib seems buggy, add an empty __register_exitproc() in startup_cm.c to avoid startup crash when using startup files
the error processing in _write_trace_semihosting_stdout() is more elaborate.
