IAR : system_stm32f10x and startup_stm32f10x_hd.s usage?

[softy342]

Hi,
What is the use of system_stm32f10x and startup_stm32f10x_hd.s files in the IAR workspace(Project).I have deleted both the files but still can see my project running just fine.I wanted to know this because I am porting a small project from IAR to Ride7 and wanted to know which files to exclude and which to include?And these two files are the reason of suspect.
Rgds,
Softy

If it still compiles, then you don't need them. Normally there is a C runtime which sets up the stack, and gets the microcontroller prepared
before jumping to 'main'. Your replacement compiler will have them too, but possibly a different name.
