The STM8 core architecture is based on the ST7, and is about 20 years old.

The original, contraversial architecture is even older than that.

It is often the case in these situations that you have customers that have standardized
on one compiler. Either many STM8 customers have asked for IAR, or one major STM8
customer has insisted upon it.

Less often, the compiler company recognizes that a particular microcontroller
architecture has significant popularity and they take it upon themselves to support the
architecture.

You may have a point. This is what IAR say about it
http://www.iar.com/website1/1.0.1.0/617/1/?item=art_art-s1/287&group=art_art_grp-s1/14
- STM "chose IAR" it says.

ST may have 'seeded' the release, and may have an eye
the existing IAR user base - I see it includes AVR, for example.

The ST8 is pretty much a 'me too' 8 bitter, rather late to the table,
so ST need leverage to get existing sockets and traction.

It also may have not been too much work, as IAR support Freescale
already, and IIRC, the ST7/8 have roots in HC05.

Also the customers may have been putting pressure on for other tools.
There is a lot more to tools that this initial purchase price.

Don't forget the MSP430, a market pretty much owned by IAR. The AVR
community has a strong inclination towards AVR Studio if I am not
completely mistaken.

That's what I can't really understand in the first place. Why did ST
come out with an STM8? I know that Cortex-M0 was later but looks like
a definite winner when comparing the two cores.
