The penalty for separate div & mod operations for your scenario is severe
on targets that require software implementation (e.g. 8 bit AVR). There is
a DivMod implementation in unit math, would be useful if this is available
in system.

I've noted that r.40170 defines MAX_OPTS_2 for AVR in aoptutils.pas. Should
the constant max_operands in avr/cpubase.pas not also be changed to 2 to
be internally consistent? If so then I can adapt avr/raavr.pas to be
consistent with a maximum number of operands of 2.

I ran the compiler test suite for the avr-embedded target to see how a
modification I made impacts things. There are however so many compilation
failures (over 1100) due to unsupported features (floating point support,
sysutils, variants, classes etc.) that it is difficult to spot relevant
I am investigating test suite failures for the avr-embedded target. The
first genuine failure is test/taddbool.pp (there are also a bunch of
incorrect exit values and other failures due to missing features such as
float, random, ansi/widestring etc.). This test fails on the last
expression

The AVR architecture uses different address spaces with potentially
different access methods [1]. Currently constant data (messages, bitmaps
etc.) are stored in flash and copied to RAM by the start-up code. Data
access makes use of the LD* instructions (and ST* if the data is
writeable).

On Linux 64 bit the compiler defaults to using the internal assembler.
When adding the -a command line option an external assembler is called.
This is unexpected based on the description of the -a option. Specifying
