Presumably the Eclipse application is using the GCC libraries, which include NewLib (which is not create for small embedded systems anyway) - while the IAR project is using IAR's own (and better for small embedded systems) libraries. More information about IAR Systems’ complete offering for Arm is available here. These are NewLib definitions, rather than GNU ARM toolchain definitions directly.

In addition, the latest IAR Build Tools for Arm provides support for Linux and Windows installations, which enables implementation in cross platform-based frameworks and large-scale deployments of critical software building and testing.
“By continuously adding early MCU core support, we also show our long-lasting commitment to our customers in bringing tools that are ready for whatever future applications they might develop.”
”The support for Cortex-M55 in our leading Arm tools will help early development based on this core in the ecosystem,” said Anders Lundgren, product manager, IAR Systems. To ensure code quality, code analysis tools are completely integrated with IAR Embedded Workbench as always. The toolchain delivers powerful optimization capabilities to assist developers in getting the most out of the performance of the MCU and yet stay as energy efficient as possible. IAR Embedded Workbench for Arm is the toolchain of choice for many companies building applications based on Arm Cortex-M cores. It brings energy-efficient digital signal processing (DSP) and machine learning (ML) capabilities to the Cortex-M family. The Arm Cortex-M55 processor from Arm is an AI-capable Cortex-M processor and the first to feature Arm Helium technology, M-Profile Vector Extension (MVE). In addition, version 9.20 of the toolchain includes support for latest microcontroller (MCU) devices from several semiconductor vendors. 5, 2021 - IAR Systems, the world leader in software tools and services for embedded development, announced that the latest version of IAR Embedded Workbench for Arm adds support for the Arm Cortex-M55 processor.
