gcc: erreur: option de ligne de commande non reconnue '-mstack-alignment = 16' lors de la construction de openjdk9 sur MacOSX

Question

Je veux construire jdk9 mais j'ai rencontré le problème suivant. J'utilise gcc & g ++ version 5.3.0 (Homebrew gcc 5.3.0) sur OSX El Capitan. J'ai également essayé d'utiliser 4.9.3, mais toujours la même chose.

Voici comment j'ai rencontré le problème:

➜openjdk9 bash ./configure --enable-native-coverage --with-toolchain-type=gcc -disable-warnings-as-errors 
➜openjdk9 cd build/macosx-x86_64-normal-server-release 
➜macosx-x86_64-normal-server-release make 

Je suis le journal d'erreur suivant:

Mais quand je la configuration --enable-debug --disable-warnings-as-errors et make la cible résultante, il n'y avait pas Erreur.

On dirait qu'il peut avoir quelque chose à voir avec l'option --enable-native-coverage et l'option -with-toolchain-type=gcc, considérant par défaut le toolchain serait clang (mais le toolchain doit être gcc pour faire --enable-native-coverage travail), mais comment puis-je résoudre ce problème?

Answer 1

-mstack-alignment=n est une option clang, non reconnue par gcc. L'option gcc correspondante est -mpreferred-stack-boundary=n

Notez qu'ils ne sont pas exactement synonymes. Pour -mstack-alignment=n, n est simplement la quantité d'alignement désirée. Pour -mpreferred-stack-boundary=n, 2^n est la quantité d'alignement souhaitée, donc:

-mstack-alignment=16 = -mpreferred-stack-boundary=4 

Notez également que n = 4 est la valeur par défaut pour -mpreferred-stack-boundary, donc pour gcc vous pouvez simplement omettre cette option.
