Add calling convention basics to X86; con+ret RegMasks. GCM computes CFG for all users. Drop unused MultiUse. Pick up reg-pressure aware ListScheduler. Re-layout CodeGen file to get code & data chunks nearer each other. minor Ary extension * ASM Printer InstSel handles folding 2+ ideal ops into 1 machine op * handle instSel for some control flow Bool,If,CProj,Region,Phi Handle 2-op expansions Shuffle instSel graph walk back again. * Basic if-block inst selects and asm prints * Add mul-by-coinstant to shift * left shift codegen basic * exclude RSP from *write* mask * 2-arg add (not immediate) mul-by-small constant opt. Some utilities. * Handle first loop Change inst sel walk again to pre-order, to set an early visit bit to stop cycles. CFGNode copies dom/loop info. Cmp not-immediate form. Ret/Fun lazy updates * inst select for new struct allocation * Float, bitwise and arithmetic operands codegen x86-64 (#150) * left shift codegen basic * sar codegen basic * merge * some basic ops * addf * divf, subf, mulf * rsp allowed in bitwise input, not output * formatting * left shift codegen basic * sar codegen basic * merge * some basic ops * addf * divf, subf, mulf * rsp allowed in bitwise input, not output * formatting * Remove non-exsting FP+imm ops * Handle first loop Change inst sel walk again to pre-order, to set an early visit bit to stop cycles.

Simplifies inst selelection which otherwise needs to undo this optimization and emit following init stores. Basic load/store for now, op-to-mem comes later add same becomes Shl by 1. Drop DivF-immiedate * extended ch13, 14,15,16 (#153) * merge2 * merge3 * Fix a few minor fuzzer bugs * Force array layout ld/st get size (but not signed/unsigned) Add unsigned LT for later range checks. * Fix a bunch of float issues was deleting required inputs * simpler invariant defensive copy inputs for simpler invariant in complex sharing patterns inc/dec form (just the opcode now). * Call & CallR X86 instructions * Add-from-memory op Remove FP immediate forms. * Remove name from TFP Never shoulda been there (but was convenient for awhile). Moved into FunNode, found by checking the linker table with a TFP. * New (#154) * merge2 * merge3 * GCM for float ops fixed, other cleanup - small extensions * call setup * merge2 * remove debug prints add check for bad call convention fix 3 tests (bad merge?) * cleanup call convention abi Needs more love at some point... * one more cleanup ABI --------- Co-authored-by: Cliff Click <cliffc@acm.org> * Add CmpMem form Common addressing mode print LEA can skip a base * Add a AddFMemX86 A bunch of mem op patterns are missing, hopefully they are just cut-n-paste from the existing patterns. * Docs * XMM reg mask fix Minor README updates * Allow inverted cmp/mem narrowing stores can bypass an AndMask Array length loads do not need control Some missing print info * Support "*ptr op= val" at least for MemAdd * missed golden rule update * Array len is u32 load-after-store zero/sign-extends if the store is truncating * One more missed case --------- Co-authored-by: hadha <helsgithub15@gmail.com> Co-authored-by: Tamás Hadházy <85063808+Hels15@users.noreply.github.com>

* Format whitespace (#86)Thalia Archibald2024-06-211-15/+15
| | | | | | | | | * Trim trailing whitespace * Ensure final new lines * Convert line endings from CRLF to LF * Replace tabs with spaces
* Backport some of the code refactoring to previous chapters (#50)Dibyendu Majumdar2023-12-071-9/+13
| | | | | | | | | | | * #44 Revise docs and comments * #44 Add starting scope to xScopes * #44 back some of the code refactoring port to previous chapters * #44 add_def should not be public * #44 add_def should not be public. Rename method names so that they are camelcase
* Chapter 7 (also 8 but not officially) (#48)Dibyendu Majumdar2023-12-031-0/+227
* #44 Start on chapter 7 * #44 Temp hack on printing to not break on cycles. Parse while statement. * #44 Remove unnecessary method * #44 Remove unnecessary phi map * #44 Phi should have existing nodes from both scopes as input * #44 We need to only insert phis once for each name that is looked up. To do so, we need to know when a named is looked up first time inside the loop body. The phi must have its second input added later on after the loop is fully parsed. * #44 Add phi also when update() is called. Only add phi if name was known at loop start * #44 Only create phi in loop body if var binding in head != body. During finish() lookup in body directly. * #44 Update the print output to make it similar to that in Xmilia's fork * #44 Disable peephole for phis & region involved in while loop * Fix broken tests Remove "disablePeephole" set in some tests, and remaining set for other tests, so a bulk test-all fails because disablePeephole is true for all. Reset disablePeephole in Node.reset Switch HashSet for BitSet (touches all). * Restructure Node class Group printing, group node & edge manipulations, group optimizations. Also, fix LoopRegion idom, it does not use Region idom but uses the original * #44 Node printing * #44 Node printing * #44 Fix control edges in loop region Change label of loop region Fix the output count in dump * #44 Revise dump output * #44 When a LoopRegionNode is duplicated, ensure the dupe is also a LoopRegionNode * #44 When a LoopScopeNode is merged, we merge the names set too * #44 When a LoopScopeNode is merged, we merge the names set too * #44 Fix print1() on RegionNode to use label() * #44 Fix bug caused by incorrect comparison of nodes between body and head of loop; the check must be performed before any phis are created * Revert "#44 Fix bug caused by incorrect comparison of nodes between body and head of loop; the check must be performed before any phis are created" This reverts commit 5f729709855046c5c10904f08385fd1aec9a298a. * #44 Fix bug caused by incorrect comparison of nodes between body and head of loop; the check must be performed before any phis are created * #44 when we create a phi incrementally for a loop region, all scopes that are cloned from the original must get the same phi update * #44 test case * #44 test case * Squashed commit of the following: commit 15666e287e6bbc39b3fcc49939165a1e908d43b2 Author: Cliff Click <cliffc@acm.org> Date: Mon Nov 27 09:45:40 2023 -0800 lazy/eager phis Eager phis by default, but can flip Parser.LAZY to switch to lazy phis. Several tests golden answers change when flipping this flag due to minor node renumbering. Phi combines same_inputs and singleUniqueInput. Fancier basic-block-like printing. Uses isMultiHead & isMultiTail which show up in many Nodes. Remove blanks in triple-quote strings. commit 6ea70182a92b7db4fe5a1fdc2c4491842ef77ee5 Author: Cliff Click <cliffc@acm.org> Date: Sun Nov 26 11:13:22 2023 -0800 Remove dead scopes Add a debug find commit a52c06a47bf1e56866d8b4d043290838f053ad76 Author: Cliff Click <cliffc@acm.org> Date: Sun Nov 26 10:21:48 2023 -0800 No constraints on backedges nicer loopy graphs commit b5ab550098355f0b66bf24b40adf2e5ba4d86e4e Author: Cliff Click <cliffc@acm.org> Date: Sun Nov 26 10:13:22 2023 -0800 Fix regression commit 30a7f5c734c686c02d3ca479914c9427b65cc469 Author: Cliff Click <cliffc@acm.org> Date: Sat Nov 25 21:51:47 2023 -0800 minor cleanup commit ad742b795ce0c93cfc82b2b11740261cfd923d02 Author: Cliff Click <cliffc@acm.org> Date: Sat Nov 25 21:47:05 2023 -0800 Fixes lazy phi Scope now takes a 'loop' option on dupping; the dup'ed Scope is filled with "Lazy Phi" sentinels - markers to indicate a Phi is need if this variable is ever referenced. If its never referenced, at the loop exit the "Lazy Phi" unwinds back to the original value. Lookup and update calls lazily insert concrete Phis over "Lazy Phis" at first touch. Rename _allScopes to _xScopes its "active" not "all" scopes now. Remove try/finally block at end, because a compiler bug throws, then attempts a GraphViz on a broken graph, then throws again, hiding the original bug. Removed 1 extra layer of Scopes. Scope printing now prints in edge order; added a reversemap for printing. More touches to ascii printing. * Remove flag to parseBlock * Bugfix for lazy on empty loop body Remove extra phi name-matching code * Keep head alive until entire end_loop merging is done * Create chapter 8 as a copy of chapter 7 * #44 Chapter 7 is now eager phis only (#46) * #44 Chapter 7 is now eager phis only * MOVE IR Printing to dedicated class to declutter Node. Remove Ary (#49) * #44 Move IR printing to dedicated class to declutter Node, and remove Ary * #44 refactor Node.delUse() to use common del() * #44 Some cleanups * #44 Some cleanups * #44 Some cleanups * #44 Some cleanups * Revert "#44 Some cleanups" This reverts commit 2702c338c8bdaa5ef2128000e26f1a8496baf34a. * #44 Some cleanups * #44 Some cleanups * #44 Some cleanups * #44 Fix typo * #44 Fix markdown formatting * #44 Remove line numbers from code snippets --------- Co-authored-by: Cliff Click <cliffc@acm.org>
