Lpc2000

I have ported code from a C51 to a XAG49 and now to the LPC (ARM mode)
and found that data size is about 15% more data and about 12% less
code size and I am getting 25% more speed at the same clock frequencey
set by all three compilers. 

I used a Tasking XA and am currently using the IAR for the ARM. The
C51 was a Kiel derivative company called Franklin Software. In terms
of the best compiler I liked Tasking and was sorry to see that they
did not make an ARM version.

There are many reasons people like the compiler or hate it. It's just
a prefernce issue more then anything else. We bought IAR which has
done a great job, but they have issues as well. Documentation being
one of them. Knowing what I know now I may have purchased the Rowley
compiler instead.

just my opinion,
Charles
