Now fixed and added a few extra tests to catch this. commit e4dcbb2 Author: Pieter Kapsenberg <pieter.kapsenberg@gmail.com> Date: Sun May 30 17:19:35 2021 -0700 Fix unused variable warnings (verilator#2991) commit f4c1a7e Author: Geza Lore <gezalore@gmail.com> Date: Sat May 29 23:46:15 2021 +0100 Emit: Fix indent tracking when // inside string literal (verilator#2990) // was so far unconditionally treated as comment. c443e22 introduced a string literal in the output that contained a http:// url, which broke the indent tracking. No functional change intended commit ef9f477 Author: Geza Lore <gezalore@gmail.com> Date: Sat May 22 18:50:55 2021 +0100 Make _ctror_var_reset and _configure_coverage static. (verilator#2977) Another step towards verilator#2958/verilator#2140. Make the mentioned generated functions static for modules (but not for classes). commit 2dd5ef5 Author: Geza Lore <gezalore@gmail.com> Date: Sat May 22 12:27:32 2021 +0100 Internals: Move --coverage and --savable check out of V3EmitC (verilator#2976) commit a43eba7 Author: github action <action@example.com> Date: Sat May 22 10:14:07 2021 +0000 Apply clang-format commit 61c9866 Author: Geza Lore <gezalore@gmail.com> Date: Sat May 22 11:13:02 2021 +0100 Internals: Generate ASTGEN_SUPER_* macros instead of expanding. (verilator#2975) astgen now generates ASTGEN_SUPER_* macros, instead of expanding the ASTGEN_SUPER itself. This means that V3AstNodes.h itself can be included in V3Ast.h, which helps IDEs (namely CLion) find definitions in V3AstNodes.h a lot better. Albeit this is a little bit more boilerplate, writing constructors of Ast nodes should be a lot rarer than trying to find their definitions, so hopefully this is an improvement overall. astgen will error if the developer calls the wrong superclass constructor. commit 6378255 Author: Wilson Snyder <wsnyder@wsnyder.org> Date: Fri May 21 20:47:53 2021 -0400 Internals: Fix some pylint warnings commit 8814111 Author: Geza Lore <gezalore@gmail.com> Date: Fri May 21 14:34:27 2021 +0100 Rework Ast hashing to be stable (verilator#2974) Rework Ast hashing to be stable Eliminated reliance on pointer values in AstNode hashes in order to make them stable. This requires moving the sameHash functions into a visitor, as nodes pointed to via members (and not child nodes) need to be hashed themselves. The hashes are now stable (as far as I could test them), and the impact on verilation time is small enough not to be reliably measurable. commit fd35492 Author: Geza Lore <gezalore@gmail.com> Date: Fri May 21 01:41:46 2021 +0100 Split V3Hashed to V3Hasher and V3DupFinder (verilator#2967) V3Hasher is responsible for computing AstNode hashes, while V3DupFinder can be used to find duplicate trees based on hashes. Interface of V3DupFinder simplified somewhat. No functional change intended at this point, but hash computation might differ in minor details, this however should have no perceivable effect on output/runtime. Implements (verilator#2964) commit a44d2b2 Author: Geza Lore <gezalore@gmail.com> Date: Thu May 20 11:30:36 2021 +0100 Move unreleased changes in right place in Changelog commit aba3883 Author: Wilson Snyder <wsnyder@wsnyder.org> Date: Wed May 19 08:14:14 2021 -0400 Commentary on MULTIDRIVEN (verilator#2972). commit 9699192 Author: Geza Lore <gezalore@gmail.com> Date: Tue May 18 19:28:48 2021 +0100 Don't merge bit select assignments in C code (verilator#2971) commit 0f7ec6c Author: Wilson Snyder <wsnyder@wsnyder.org> Date: Mon May 17 18:24:18 2021 -0400 Fix missing array include (verilator#2966) commit 471f14d Author: Geza Lore <gezalore@gmail.com> Date: Mon May 17 13:26:24 2021 +0100 Clean up V3Combine (verilator#2965) - Remove dead code - Simplify what is left - Minor improvements using C++11 - Remove special case AstNode constructors used only in one place in V3Combine (inlined instead). commit bdc162d Author: Wilson Snyder <wsnyder@wsnyder.org> Date: Sun May 16 18:38:43 2021 -0400 Fix 16.04 gcc warning commit 706842d Author: Wilson Snyder <wsnyder@wsnyder.org> Date: Sun May 16 15:11:25 2021 -0400 CI: Disable Ubuntu-18.04 clang (verilator#2963) commit 31779b8 Author: Yutetsu TAKATSUKASA <y.takatsukasa@gmail.com> Date: Sun May 16 19:01:03 2021 +0900 Format time string using integer (verilator#2940) Co-authored-by: Wilson Snyder <wsnyder@wsnyder.org> commit 80d62ad Author: Geza Lore <gezalore@gmail.com> Date: Sat May 15 21:10:16 2021 +0100 Make all AstNode* base class constructors protected. (verilator#2962) No functional changes intended. Boring patch in the hope of being helpful to new contributors. Although AstNode* base classes needing to be abstract is described in the internals manual, this might provide a bit of extra safety. commit 38cab56 Author: Geza Lore <gezalore@gmail.com> Date: Sat May 15 18:04:40 2021 +0100 Add --reloop-limit argument (verilator#2960) Add --reloop-limit argument commit 828f78e Author: Geza Lore <gezalore@gmail.com> Date: Sat May 15 16:05:24 2021 +0100 Don't emit empty files with low split limits (verilator#2961) Attempt to split output files when we know a function will actually be emitted, otherwise we might end up with empty files. commit 5e95cc9 Author: Geza Lore <gezalore@gmail.com> Date: Sat May 15 15:56:28 2021 +0100 Internals: Make AstAlwaysPost an AstNodeProcedure. (verilator#2959) This seems to belong there, eliminates some code duplication in V3Clock, and also enables splitting AstAlwaysPost statements into different functions in V3Order, but should otherwise have little effect. commit 88fed4b Author: Wilson Snyder <wsnyder@wsnyder.org> Date: Thu May 13 18:56:07 2021 -0400 Commentary on traces (verilator#2925) commit 3718fe1 Author: Wilson Snyder <wsnyder@wsnyder.org> Date: Thu May 13 18:34:20 2021 -0400 Commentary (trigger rebuild) commit a4ab3e1 Author: Ameya Vikram Singh <ameya.v.singh@gmail.com> Date: Thu May 13 23:56:53 2021 +0530 Update latest C++ Standard Compilation flag (verilator#2951) For SystemC Project sets the CXX_STANDARD flag from SystemC CMake build config. commit 9c85426 Author: Yutetsu TAKATSUKASA <y.takatsukasa@gmail.com> Date: Thu May 13 06:45:56 2021 +0900 Internals: Fix build failure on older gcc such as 4.8.5 on CentOS7. No functional change is intended. (verilator#2954) commit e3b20a3 Author: Yutetsu TAKATSUKASA <y.takatsukasa@gmail.com> Date: Wed May 12 00:45:43 2021 +0900 Internals: Mark VerilatedContextImp::timeFormatSuffix() const (verilator#2947) commit f7c23c4 Author: Yutetsu TAKATSUKASA <y.takatsukasa@gmail.com> Date: Tue May 11 22:38:13 2021 +0900 Internals: Set missing timescale though it is not referred yet. (verilator#2946) commit 00cedf3 Author: Yutetsu TAKATSUKASA <y.takatsukasa@gmail.com> Date: Tue May 11 22:27:31 2021 +0900 Tests: Add a test to check if there is overflow or rounding (verilator#2945) commit 1422c23 Author: Geza Lore <gezalore@gmail.com> Date: Tue May 11 12:44:07 2021 +0100 Split procedures to better respect --output-split-cfuncs (verilator#2942) CFuncs only used to be split at procedure (always/initial/final block), which on occasion can still yield huge output files if they have large procedures. This patch make CFuncs split at statement boundaries within procedures. This has the potential to help a lot, but still does not help if there are huge statements within procedures. commit 1a63782 Author: Geza Lore <gezalore@gmail.com> Date: Mon May 10 22:15:12 2021 +0100 Emit 'else if' without nesting. No functional change intended. (verilator#2944) Instead of: if (a) { x; } else { if (b) { y; } else { if (c) { z; } else { w; } } } Emit: if (a) { x; } else if (b) { y; } else if (c) { z; } else { w; } commit 267c6f6 Author: Geza Lore <gezalore@gmail.com> Date: Mon May 10 18:01:11 2021 +0100 Improve Reloop to accept constant index offsets. (verilator#2939) V3Reloop now can roll up indexed assignments between arrays if there is a constant offset between indices on the left and right hand sides, e.g.: a[0] = b[2]; a[1] = b[3]; ... a[x] = b[x + 2]; commit 45fbd98 Author: Yutetsu TAKATSUKASA <y.takatsukasa@gmail.com> Date: Sun May 9 07:04:22 2021 +0900 Use V3OptionParser in verilator_coverage (verilator#2935) * Internals: Mark unused to avoid compilation failure. No functional change is intended. * Use V3OptionParser in VlcMain.cpp commit f6c0108 Author: Geza Lore <gezalore@gmail.com> Date: Sat May 8 20:04:56 2021 +0100 Optimize large lookup tables to static data (verilator#2926) Implements verilator#2925 commit 37d68d3 Author: Jonathan Drolet <jonathan.drolet@riedel.net> Date: Sat May 8 08:42:00 2021 -0400 Support --trace-fst for SystemC with CMake (verilator#2927) commit 5e56f4d Author: Yutetsu TAKATSUKASA <y.takatsukasa@gmail.com> Date: Sat May 8 21:20:26 2021 +0900 Tests: Enable undefined behavior sanitizor when --sanitize is set. (verilator#2923) commit 2bf248b Author: Jonathan Drolet <jonathan.drolet@gmail.com> Date: Sat May 8 08:18:08 2021 -0400 Add TRACE_THREADS to CMake (verilator#2934) commit 39ce2f7 Author: Yutetsu TAKATSUKASA <y.takatsukasa@gmail.com> Date: Sat May 8 09:45:58 2021 +0900 Internals: Remove VerilatedVcd::m_suffixesp. No functional change is intended. (verilator#2933) Reasons are: - it's error prone to keep updating whennever m_suffixes is resized - invalid pointer may be set when there is not signal to trace as in t_trace_dumporder_bad commit 9797af0 Author: Yutetsu TAKATSUKASA <y.takatsukasa@gmail.com> Date: Sat May 8 07:16:40 2021 +0900 Introduce a macro VL_ATTR_NO_SANITIZE_ALIGN to suppress unaligned access check in ubsan (verilator#2929) * Add VL_ATTR_NO_SANITIZE_ALIGN macro to disable alignment check of ubsan * Mark a function VL_ATTR_NO_SANITIZE_ALIGN because the function is intentionally using unaligned access for the sake of performance.
