gcc 64ビットで構築されたApacheバイナリに32ビットと64ビットが混在しているのはなぜですか？

Solaris 10では、64ビットgcc 4.9.0を構築しました。少なくとも私はそうだったと思います。 Apacheやその他の必要なツールに基づいてスタックを構築しています。

Apacheをビルドすると、file64ビットhttpdが表示されます。

file apache-test/bin/httpd 
apache-test/bin/httpd:        ELF 64-bit MSB executable SPARCV9 Version 1, dynamically linked, not stripped, no debugging information available

したがって、これは私のGCCが64ビットであることを示しています。ただし、バイナリをビルドしたディレクトリからfor f in *; do file $f; done取得したディレクトリ全体に対してファイルを実行します。

for f in *; do file $f; done

なぜそれほど多くの32ビットバージョンが表示されますか？ gccを使用してApacheをビルドする場合、gccファイルに32ビットとマークされていますが、どのように64ビットになりますか？

SolarisのGCCには、LinuxのGCCとは異なるデフォルト値があります。

64 個のバイナリをコンパイルするには、以下を追加する必要があります。

-m64

コンパイルとリンク行に。

これに関して、GCCはSolaris Studio Cコンパイラと互換性があります。

SPARCでは、プログラムを32ビットにコンパイルしても、64ビットが追加のレジスタを提供するx86と同じ欠点はありません。
