シェルティさん、こんにちは。NoMaYです。別スレッドのFreeRTOSのRTOSDemoプログラムを作っていて気付いたのですが、掲題の件、以下の結果となっていて、CC-RXでなぜ効き目が弱いのか、シェルティさん経由で、CC-RX開発チームに調べて頂くことは出来ないでしょうか？(プログラムの構造上、FullDemoとSimpleBlinkyDemoの2種類のDemoを切り替えられるようになっていて、SimpleBlinkyDemoに切り替えた場合には沢山の未使用の変数/関数が生じるようになっているものです。) なお、使用したCC-RXはV3.02です。CC-RX版のプロジェクトのファイル一式 (e2 studioにzipファイルを直接インポートすることは不可。CS+にも対応。)FreeRTOSDemo_CCRX_20200707.zip 983KBCC-RXの場合

もっとも、調べて頂くことは出来ないでしょうか、とは言ったものの、ICCRXについてもGNURXについても分からないだろうと思いますので、CC-RXの挙動で取っ掛かりになるのではないだろうかと思った点を、以下に書いてみました。CC-RXの未使用の変数/関数を削除する最適化の疑問点● リンカにインフォメーションメッセージでunused symbolを表示させたところ、以下のようなdeleteされたシンボルのリストが表示されたのですが、それでもずっと沢山のunusedシンボルのリストが表示されました。直感的に、なぜunusedシンボルが残っているのか(deleteされていないのか)不思議な気がするのです、、、(その一方で、_Except_Vectorsや_Reset_Vectorがunusedになっているのも不思議ですが、、、)リンカのインフォメーションメッセージのdeleteされたシンボルのリスト
