Hi,
This patch converts the avr backend to MODE_CC. It addresses some of
the comments made in the previous submission over here
(https://gcc.gnu.org/pipermail/gcc-patches/2020-December/561757.html).
Specifically, this patch has
1. Automatic clobber of REG_CC in inline asm statements, via
TARGET_MD_ASM_ADJUST hook.
2. Direct clobber of REG_CC in insns emitted after reload (pro and
epilogue).
3. Regression testing done on atmega8, atmega128, attiny40 and
atxmega128a3 devices (more details below).
4. Verification and fixes for casesi and avr_compare_pattern related
code that inspects insns, by looking at avr-casesi and mach RTL dumps.
5. Use length of parallel instead of passing in operand counts when
generating code for shift patterns.
6. Fixes for indentation glitches.
7. Removal of CC_xxx stuff in avr-protos.h. In the places where the
macros were still used (cond_string), I've replaced them with a bool
hardcoded to false. I expect this will go away/get fixed when I
eventually add specific CC modes.
I could not find a way to use define_subst to generate
define_insn_and_splits, so the duplication of patterns remains. And
clobbering REG_CC for all insns forces the clobber to be added in all
(pre-reload) places where such insns are generated, which appears to be
equally invasive in terms of changes, so I did not do that as well. I'd
planned to try a parallel approach of adding clobbers early and doing
away with define_insn_and_splits, like what the cris port does, but I
ran out of time.
Things still to do:
1. Adjustment of peepholes/define_splits to match against patterns
with REG_CC clobber.
2. Model effect of non-compare insns on REG_CC using additional CC
modes. I'm hoping to use of a modified version of the cc attribute
and define_subst (again inspired by the cris port), to do this.
3. RTX cost adjustment.
Some additional comments for questions Johann asked in the previously
submitted patch.
1. avr_optimize_casesi changes
There is one fewer insn now, as there is no cc0 setting insn. Also
the previous code generated two new insns, inserted them before
insns[1], and later deleted insns[1] and insns[2], where insns[2] is
the (set cc0 (compare...)). With REG_CC, there is no separate compare
insn - the jump_insn (insns[2]) has to be deleted and replaced.
Inserting a new jump_insn before a to-be-deleted
jump_insn results in flow verification failure (jump_insn inside a
bb). Inserting the new insns after the to-be-deleted jump_insn works
fine, hence this change
- emit_insn_before (seq1, insns[1]);
+ emit_insn_after (seq1, insns[2]);
I manually verified that the generated patterns are identical,
except for the CC0 -> REG_CC change.
2. @@ -459,7 +460,8 @@ (define_split

[(set (reg:HI REG_SP)
(reg:HI REG_Y))])
This splitter conditionally replaces operands[0] with REG_Y - the input
template is
[(set (reg:HI REG_SP)
(match_operand:HI 0 "register_operand" ""))]
However, this fires even if operands[0] is already REG_Y. try_split
gives up if it sees the same pattern returned from the split, and
therefore movhi_split fails with a could-not-split-insn ICE in final.
Adding the condition to exclude REG_Y fixes that problem.
Reg testing results:
Both atmega128 and atxmega128a3 show zero regressions. For attiny40,
there are about ~30 execution tests with FAIL->PASS, and a few cases
(~10) of compilation tests with PASS/FAIL->UNSUPPORTED and
UNSUPPORTED->FAIL because of code size changes.
For atmega8, there are a bunch of execution failures because avrtest
does not correctly simulate backward jumps that wraparound, reporting
invalid PC because it is configured for a flash size of 0x40000. With
MAX_FLASH_SIZE set to 8*1024 instead, there are no execution
failures. ~25 tests report PASS->UNSUPPORTED because of code size
changes.
I intend to continue working on the things-to-do in my spare time, but
I figured I'd submit these changes, in case I run out of time before
cc0 gets ripped out.
FWIW, I tried benchmarking the current implementation against mainline,
using the embench-iot suite (https://github.com/embench/embench-iot).
The results, after building with
./build_all.py --arch avr --chip=atmega64 --cc avr-gcc --ld avr-gcc --verbose --cflags="-mmcu=atmega64 -Os" --ldflags="-mmcu=atmega64 -Os" --clean && ./benchmark_size.py
