+【Issue#1176 動作確認】
+□ テスト内容
+1. 指摘の現象が解消されていることを確認する。
+
+C1176T01 指摘の現象が解消されていることを、テストプログラムを用いて確認
+         mcexec test_mck -s getrusage -n 2
+
+2. 修正が正しく動作することをテストプログラムを用いて確認する。
+   変更は以下の3点である。
+   (1) システムコール出口で高速化のためシグナル処理を呼び出していなかったが、
+       ロック無しでシグナル受信を判定後に、シグナル処理を呼び出すようにした。
+   (2) futex_wait 処理で高速化のためシグナル受信の判定処理をしていなかったが、
+       ロック無しでシグナル受信を判定し、受信していた場合にfutex_wait
+       処理を脱出するようにした。(その後、システムコール出口でシグナルが
+       処理される)
+   (3) 高速化のためシステムコール出口での再スケジュール処理を呼び出して
+       いなかったが、ロック無しで再スケジュール要否を判定し、再スケジュールが
+       必要な場合は再スケジュール処理を行うよにした。
+
+C1176T02 システムコールオフロード中にシグナル受信し、システムコールが中断
+         してシグナル処理されることを確認
+
+C1176T03 futex_wait 処理中にシグナル受信し、futex_waitが中断してシグナルが
+         処理されることを確認
+
+C1176T04 2つのプロセスを同一CPUに割り当てた状態で、各々1秒sleepするとき、
+         それぞれのプロセスが正しく処理されることを確認。
+         sleep完了後にシステムコール出口で再スケジュール処理が行われる
+
+3. 修正が既存処理に影響しないことをLTPを用いて確認する。
+   シグナル関連処理(正常系)を中心にテストプログラムを選定した。
+
+C1176T05 kill01: kill の基本機能の確認
+C1176T06 kill12: kill, wait, signal の組み合わせ確認
+C1176T07 pause02: pause の基本機能の確認
+C1176T08 sigaction01: sigaction の基本機能の確認
+
+□ 実行手順
+$ make test
+
+実行できない場合は、C1176.shの以下の行を適切に書き換えた後に実行。
+BIN=          mcexec が存在するパス
+SBIN=         mcreboot.sh が存在するパス
+LTP=          LTP が存在するパス
+OSTEST=       OSTEST が存在するパス
+
+□ 実行結果
+C1176.txt 参照。
+全ての項目が OK となっていることを確認。
