Hopefully someone can tell me how to resolve assembler errors in FreeRTOS Demo for Renesas RL78.  
Using:  
IAR EW for RL78 Version 2.21.2  
IAR EW Version 7.4.1.4269  
FreeRTOS Version 8.2.3  
RTSDemo - YRPBRL78G13 (YRPBRL78G13 is #defined).

An example of the error messages:  
ExampleISR.s87  
Error[As078]: Directive COMMON not supported in ELF mode. C:\FreeRTOSV8.2.3\FreeRTOS\Demo\RL78\_multiple\_IAR\ExampleISR.s87 125  
Error[As078]: Directive ORG not supported in ELF mode. C:\FreeRTOSV8.2.3\FreeRTOS\Demo\RL78\_multiple\_IAR\ExampleISR.s87 130  
Error while running Assembler

Perhaps the assembler syntax has changed between compiler versions. I  
would recommend checking the change history for the compiler. Let us  
know what you find.

Appears that these two Assembler Directives were obsoleted in the transition form IAR v4.x to v5.x. IAR current version is now at v7.5. Would be useful if the Assembler files for the FreeRTOS Demo for RL78 processors were updated to work with the current Assembler.  
Thanks for your interest!!

Thanks for the information. Please post the necessary updates so the  
files can be updated in the repository.

I have the same problem with IAR ver. 8.5. Can someone provide solution?  
I am using FreeRTOSv202112.00\FreeRTOS\Demo\RL78\_multiple\_IAR
