Hi Steven,

I've used C17 to translate a small 800 lines plain C program  file in a huge
(2 x 500 Ko asm real source, not .LST) bi-17C44 asm project...


The C source was very uneasy (regression risks) to translate by hand
(rotation,
shifting, matrix using, etc...).

I've created a small label (reg & address) "relocator" program to parse the
asm, xref files produced from C source and recreate all we need in a
fixed-address project (all .asm are linked by include statement, not by
linker).

The C source (very standart one) was well tested in a PC...
The asm (of course) release did not work...

Well, after intensive debug session, I had to fix many many bugs in C17 asm
production code...
(try "for" statements with <= or >= condition... The asm code produced is
simply... wrong... (infinite loop)...
There is many other problems (don't remember)...


The previous Microchip C compiler was a toy (not a real C compiler IMHO),
This one seems far more better but has serious bugs.
I not recommend using C with PIC : write pseudo-code in comments with real
asm code...


To be fair :

No stability problem seen on NT 4.0 or WFW 3.11...
The produced asm code is speed and rom efficient :
I could not gain more than 10-12 % by hand profiling !!!
With special programmer care : ram use is also efficient (for a C compiler
point of view)
