Any uC manufacturers have free c compilers?

Analog doesn't exactly tout their microprocessors in an obvious
fashion on the front page of their site.  They are not included in the
embedded processing section but rather under Analog microcontrollers.
Take a look at

ADUC7033
ADUC7032-8L


They have 12V and 200mV A/D inputs (battery Voltage and current shunt
inputs).  And since they are ARM parts GCC and eval commercial
packages should both work.

I don't know how readily available they are, but I do have a project
in mind that might make use so a may check up in a while a find out
(it's still a project that's on the horizon rather than active
though).

I have used the gnuarm gcc compiler, for the ARM7 TDMI based Analog 
Device chip ADuC7026 and ADuC7028.
I have used version 2.98 and 4.1, and both are excellent products really 
solid. The 4.1 version generates more compact code (about 30 % less in 
size). I have never run benchmarks, but often smaaller code is also faster.

I am delighted with the quality, reliability of the 
compiler/linker/assembler, which in my view is superior to many 
"commercial" compilers.
Even the documentation is better that many other compilers.
The assembly/C programinng API is quite good too.
The fact that the compiler is free open source does not spoil the pot!

After talking with the powers that be, I decided to rewrite the
confusing sections myself, and they agreed to use my changes.
Hopefully it's more obvious what we do, without miscommunicating
anything.

Thanks for the feedback!

You are just as my expereince
I kept some 8051-alikes from fault VHS and 9600 baud modems
With SDCC http://sdcc.sourceforge.net compiler and Code Blocks
http://www.codeblocks.org/ IDE i worked very well
The 1st program was(after PCB cleaning from useless components)an LCD
tester,a modified http://freewebs.com/80x51/source/LCD/lcd.h version for
port1 taken in http://mcu-programming.blogspot.com/search/label/LCD and I
soon restarted programming

Main problem at beginning was intervacing my Willeprom to Kubuntu,but it's
all done! :-) 

All for free,funny and brainstorming...
Now my main supply is flea market :-D
