我在SunOS 5.11（Solaris 11.3）上的Sun Studio 12.3下工作。我需要查看Sun Studio定義的宏以修復套件下的錯誤報告。這與Solaris and Preprocessor Macros類似，但引用的問題使用GCC及其預處理器;而不是Sun Studio的預處理器。如何在Sun Studio下打印預處理器宏？
我運行了CC -flags，但我沒有看到類似於GCC的cpp -dM或g++ -dM -E - </dev/null的選項。 CC確實有-E，但其相當貧血，不打印任何預處理器定義：
$ echo $CXX
/opt/solarisstudio12.3/bin/CC
$ $CXX -E /dev/null
#1 "/dev/null"
使用一個真正的測試文件產生相似的結果 - 預處理宏缺失：
$ $CXX -E test.cxx | grep __cplusplus
$
我還發現在Sun Studio手冊中討論預處理器宏。表A-2是可以的，但它也主要是貧血。其缺少的基礎知識如__cplusplus，其缺失的其他定義如_RWSTD_NO_CLASS_PARTIAL_SPEC。
如何在Sun Studio下打印預處理器宏？
$ /opt/solarisstudio12.3/bin/CC -flags

非常感謝你。男人，我不知道我錯過了那個選擇。我想這是因爲我正在搜索「預處理」關鍵字，而不是「宏」關鍵字。 – jww
相關，我瞭解到Sun Studio沒有定義'__SSE2__'，'__SSE3__'，'__SSSE3__'和朋友。但是，基於編譯器，它樂於消耗內在的東西。 – jww
