Fixes some bugs `flit x; return x ^ 0;` should give an error instead of returning the plain `x`
|

Renumber chapters 10a, 10b, 11, 12, 13, 14 -> 10, 11, 13, 12, [11,14].
Split ch 17 into a 17a and 17b; shuffle around im/mutable syntax to be consistent, and present it more slowly.
THe new immutable syntax is pushed through all later chapters

Same as the graph viewer, moves a lot of code out of all Nodes
|

Integrate with ch15 NewNode creating aliases

* Extend and backport SubNode peephole
* Add tests
* Restrict subtraction zero peepholes to integer operands
Require resolved integer mode in chapter 25 so zero subtraction preserves floating-point signed zero. Keep nonnumeric operands in the graph for subtraction diagnostics.
Add signed-zero coverage from chapter 12 and null-subtraction diagnostics from chapter 22. Confirmed the regressions fail on the original PR. Full Make suites pass in chapters 4-25 (5462 tests), including fresh chapter 25 sys.o compilation.

Fast forward/reverse, pick-a-frame.
Shorter type names.
|

all chapters, a little sharper for int ops
|
| |
|
|
| |
Phis stay with regions, stop sinks to bottom,
|

Remove the _anti field.
Remove the isPinned() call.
Add a copyEmpty call.

RISC5 changes.
Some missing x86 ops.
Still needs some calling convention love.
* First cut regalloc working
Biased coloring; tracking splits around a LRG.
Separate split for self-conflicts.
postColor to remove junk splits.

RetRISC handls FPR
remove extra RegMask constructurs
* Progress reg alloc
Handle multi-node projections.
A little smarter about 2-addr scheduling
RegAlloc must-have single registers removes from other masks instead of interfering; had the mask removal backwards in a few cases.
LRG/RegMask COW expand masks before mutating.
Clone small constants instead of spilling.
Alloc & ProjX86 get output reg masks.
Full print large reg masks with sp+offset

Co-authored-by: Cliff Click <cliffc@acm.org>
* Update Chapter20Test.java
* Weaken range-check test
since no range checks... test cannot fail (pass)
* Fix issue #161
Error adding 'null' and '5'
* bug fixs, cloning constants
Fix bug missing Find.
Fix bug setDef does unordered removal from basic blocks.
Use cloned constants for spilling.
* RA fixes
SplitSelfConflict MUST split before uses and after defs.
Split global constants across functions
Missing find in union;
Inserting split after new inserted wrong place
Pre-remove null LRGs before color.
Bias color hunts through Phis
Shorten InstructionSelection.
Rename !unified() to leader()
AddMemX86 is 2-addr
Add CastXXX to preserve register across cast.
* Allow a killMap to kill regs.
Bugfix scheduler.
Bugfix spiller - self-conflict order depended on hashtable iteration order, which depended on System.hashCode which would vary run to run.
Improvements to coloring
Improvements to spill quality testing
* Added flags-kill for XOR
* Missing add-deps from fuzzer
* Update Chapter14Test.java
* remove jukn files
* minimal "make release"
* Add regkills in IFG building
Fix bug LRG union stats
Adjust self-conflict splits to be slightly less aggressive
In every use-side split, dont split-after-split same block.
NewNode is a multi, does not define a register
* RA improvements
Attempt to commute to keep reg-masks compatible.
Clones with kills (x86 XOR killing flags to zero) fail before the flag-def.
Bugfix failed to color last lrg.
More smarts on picking trivial LRGs during coloring
Drop isSplit, add SplitNode
Pass regalloc round to all splits for debugging
Self-conflict no split on loop backedge.
Handle split that gets made goes dead
No-reg-mask spilling handles case with many def/uses.
Add DivIX86
BrainFuck, MergeSort now allocate as testing
* Push l,ast change, unbreak branch
* Finally pass the `new [u8]` double-copy test
* Fix several ARM reg setup problems
Finish Split bypass check
ARM: rsp is also a fixed zero, in R31. R0 is a valid register.
CallArm prints args, passes TFP for arg selection. Does not return a register. All CallEndARM which DOES return a register. Parms missing tfp for float args. ProjARM after a New missing regs. RetARM missing RPC.
Remove hopeful DivIX86
* Bunch of minor arm, risc fixes
small constants not cloning
* Much ARM fixage
One More Go-Round with Better Biased Colors
Fix bug picking deepest spills to bias.
ARM: remove default 2-address. Fix regmask overflow. Rename some ops to be canonical.
* Fixes to release
Port does not have to be in a Simple named directory.
Call convention is just a string, no enum
Missed some tests running RISC, ARM.
* Minor release change to allow another foreign port
* Allowing non-Simple repo ports
Expanding public API slightly so alternative (non-Simple repo) ports can happen.
RegMask supports single-bit-set and a long bitmask.
Bugfix GCM splitting multiple global constants.
Bugfix LCM grabbing a projection vs multi
Bugfix RegAlloc when avoiding splitting a clonable
Source code in release
More timing in CodeGen
* Cleanup call ABI presentation
Everybody uses the same names, same code shapes
* Caller save regs
...not callee save yet
* Expose caller save regs
* More x86,risc,arm call convention fixes
Collect callee and caller save masks (inverts of each other, except for spills).
Reorg layout to be closer to each other; remove dead mask definitions; add final keyword
* Callee-save registers
Callee-save registers and masks and inserting LRGs for same and spilling and picking good spills. Insert CalleeSaveNodes and edges to RetXXXs and RegMasks for those edges.
Iterators for regmask.
Better printing post-allocation
* RegMask supports 128 bits
All regs available arm, risc.
MergeSort compiles & runs
* Fix risc5 compares
No flags on risc5.
Branch takes 2 inputs (one can be imm12).
Float compare only sets a GPR to 0/1.
Bool has a isFloat
Common risc5 imm-form handling
* yank MulIRISC
* fix arg flags reg
Arm split op can spill flags
bugfix RegAlloc 1st real >=64bit reg num
* Update Chapter20Test.java
* Turn off transpile tests
which are broken for some time now
* A lot more readme
* better flags
ListScheduler stalls cmp/jmp in the same block; avoids some flags spills.
Make CmpIX86/ARM rematieralize.
Bugfix: remove some include x86/risc/arm in other dirs.
Canonicalize boilerplate fcn order
* regalloc improves
Use FltRISC, not clonable requires a spill from int->flt regs.
new splits track origin LRG, so later splits in the same pass know what lrg a spilled input is.
* RA improvements & fixes
Bugfix on split loop-depth computation.
Track killmask kills, which are always capacity kills and require more spilling.
Rename the riscv registers canonically, so I can tell them part! Definitely no GP or TP in Simple.
Node insertAfter bypass a little more conservative.
* RA bugfix
remove unified failed live ranges
* easier access for remote ports
debug support
* Lots more comments
* bugfix
infinite peep cycle on (17 ^ 3.14), i.e. bad program
* Fix imm12 shift

More compiler driver cleanup: Stop only has Return inputs, never an expr. Drop extra lexical scope. Linker table moves to CodeGen.
Replace evaluator with a simpler design; I was unable to get the current design to work with the other changes.
Updates to old eval; proper idoms; forced type checks; extensions for Fun, Return, Call, CallEnd.
Accessor find next control to execute. Accessor for deciding when its ok to optimize a Function/Return, Call/CallEnd, Stop, ScopeMin (merge)
Add local scheduling pass.
IRPrinter uses SB instead of StringBuilder
Spelling SubF comment

* Folding loads before phis needs more work
Have to check load alias & offset/field match.
Could work for stores as well, will need to check more inputs
* Preserve SAR/SHL sharpness with variant shifts
* phi-node cloning honors unrelated argument types
* bool can never do phiCon
* dont fold shifts outside the range 0-63
* Now allowed to fold Loads in Phi
Because honors glb() of inputs
* Correct shr of mixed sign
* yank load merge again
needs an anti-dep check
* Stop phi-merge if it loses precision
* wrap bug
