The string to integer template checked the range of the value in every instantiation. Six of the seven integer instantiations use a conversion method whose type is not wider than the type of the value. For those the two comparisons were constant and the code behind them was dead. Coverity reported this as CID 1700407 to CID 1700418. Emit the range check only where the type of the conversion method is wider than the type of the value. Every instantiation which sets STRING_TO_RESULT_TYPE gives the maximum of that type in STRING_TO_RESULT_MAX. The template compares the two maxima. An undefined macro drops the check without a diagnostic, so a missing STRING_TO_RESULT_MAX is an error. Behaviour is unchanged. Where the two types have the same width, the conversion method sets ERANGE. The template already turns ERANGE into RTEMS_INVALID_NUMBER. Update #5708.

Real-Time Executive for Multiprocessing Systems
RTEMS is a real-time executive (kernel) which provides a high performance environment for embedded applications with the following features:
- Standards based user interfaces.
- Multitasking capabilities.
- Homogeneous and heterogeneous multiprocessor systems.
- Symmetric Multiprocessing (SMP):
- Cluster scheduling: Job-level fixed prority scheduler (EDF) with support for one-to-one and one-to-all thread to processor affinities.
- Locking protocols with transitive priority inheritance, priority ceiling, MRsP and OMIP.
- Event-driven, priority-based, preemptive scheduling.
- Scalable timer and timeout support.
- Optional rate monotonic scheduling.
- Intertask communication and synchronisation.
- Priority inheritance.
- Responsive interrupt management.
- Dynamic memory allocation.
- Dynamic code loading using run-time link editing.
- File systems, IMFS, FAT, RFS, JFFS, NSFv4 (with LibBSD)
- High level of user configurability.
- Link-time configurable schedulers.
- Linker-set based initialization (similar to global C++ constructors).
- Drivers for I2C, SPI and LibBSD has NIC, USB, SD/MMC and Framebuffer.
- Open source with a friendly user license.
