Benchmark test results for R32C C/C++ compilers |
| Version 1.30 of IAR Embedded Workbench® for R32C is based on the latest compiler and debugger technology from IAR Systems. In addition to all the powerful and unique features introduced in this new release, version 1.30 of IAR Embedded Workbench for R32C generates very compact code, in average about 29% less code than Renesas NC30 for the tested code examples. |
Tools in benchmark test |
This benchmark test compares the total size of linked code, const and initialized data area between the following tools:
- IAR Systems: EWR32C v1.30 (options: -z9 --double=32 --fp_model=fast --code_model=f --data_model=n)
- Renesas: NC100 v101r00 (options: -c -OR_MAX -fnear_ROM -fuse_FPU)
