This tests are intended to reveal the respective PRs because the test
case is more stable under slight variations in code (both of
application or compiler).
This test case migh also be helpful for older versions of avr-gcc, in
particular if PR41894 is actually fixed.

This patchlet adds -finline-limit=0 to dg-options in
testsuite/gcc.target/avr/torture/pr41885.c
because otherwise optimizers will fold all tests and actually no test
function is called when optimization is on. The test case still passes
all tests.

The rotlmode3 expanders (mode \in {HI,SI,DI}) violates synopsis by
using 4 operands instead of 3. This runs in ICE in top of
optabs.c:maybe_gen_insn.
The right way to do this is to use match_dup, not match_operand. So
This is fix for a minor performance regression introduced by my changes in
trunk r175956: To load a 32-bit constant like 1 into R2, 4.6 uses
CLR R2
CLR R3
MOVW R4,R2
INC R2
whereas trunk prints the longer
CLR R2
INC R2
CLR R3
CLR R4
CLR R5
As proposed in PR45099, avr-gcc will now just print a warning instead of an
error when a fixed register is needed to pass a parameter to a function.
That way the user can inspect the source, and there are situation imaginable
where clobbering a fixed register is not a problem.
Committed as trunk
This patch improves IOR, XOR, AND for HI and SI.
There is room for improvement in the current implementation:
- better analysis if a scratch is actually needed
- add clobber operands to some insns
- use 8-bit scratch instead of reload the constant
- reuse value in scratch register if known

Where's the proposal in the PR? I see a problem report that was
addressed
This adds rotate left/right by 1 for HI and SI and rotates by QI.
It's all straight forward. The test case in the PR leads to generation of the
new rotate patterns.
Passed without regressions.
Ok?

* config/avr/avr.md (rotlqi3): Support all offsets 0..7.
This patch adds the PLUS part to fix the PR.
addsi3 has a 8-bit scratch register now so that constants that are not covered
by the constraints won't force a reload of the constant.
The output routine tries adding the constant and subtracting the negated
constant and then chooses the shortest

Also, I am curious about one thing: while this is of course a very
pragmatic solution, you could also convert AVR to get rid of CC0, do
this at expansion time, and get split-wide-types to work as intended.

This is the compare part to fix PR50447.
Just like the preceding changes to fix PR50447 it's a micro-optimization to
smarter print-out of instructions.
The patch covers comparisons against HI and SI integers.
The byte-wide comparison allows reusing the value in the scratch register and
This is just a code clean-up that deals with loading 16-bit constants (HImode).

o To print the constant output_movhi can use output_reload_inhi
