GPC's inline assembler is not compatible to BP's. It uses
AT&T syntax, supports a large variety of processors and works
together with GPC's optimizer. So, either convert your inline
assembly to AT&T syntax, or (usually better) to Pascal, or put it
into an external file which you can assemble with your favourite
(32 bit) assembler. A tutorial for using the GPC inline assembler is
available at
http://www.gnu-pascal.de/contrib/misc/gpcasm.zip
Since many things you usually do with assembler in BP are provided by GPC's Run Time System (RTS), you will not need the inline assembler as often as in BP. (See Portability hints.)
The same applies to BP's inline
directive for hand-written
machine code. GPC's inline
directive works for Pascal
routines (see Miscellaneous), so you'll have to convert any
hand-written machine code to Pascal (and thereby make it more
readable, portable and easier to maintain while still getting the
performance of inline code).
