gcc(gnu), clang(llvm)コンパイルエラー・警告比較(1) D_04_03.c。docker(155)
やってきました。
gcc(gnu) clang(llvm)コンパイルエラー比較
長らくごぶさたしていました。
ISO/IEC JTC1 SC7から ISO/IEC JTC1 SC22へのリエゾン担当だった小川清です。
リエゾン担当になった理由は、一つには、MISRA からの意見が通らないという声を聞いて、品質の観点で何かお手伝いすることがないか調べるためでした。
IEEEのJim Mooreと二人での担当です。
数年で成果がでないまま退任したのは残念です。
MISRAはその後、リエゾンになり、今では毎年報告をあげてくれています。
MISRA の解説書は有料ですが、Codeは無償であげてくれています。

順にコンパイルエラーが出たものを比較し、
エラーを取るのなら取ってみます。
-Wall でコンパイルしています。

まず、エラー・警告の違いがあるものをまず記録。
D_04_03.c
D_04_03.c:24:8: error: expected '(' after 'asm'
asm { "CLI" }; /* Non-compliant */
^
D_04_03.c:26:8: error: expected '(' after 'asm'
asm { "SEI" }; /* Non-compliant */
^
2 errors generated.
D_04_03.c: In function 'D_4_3_1':

Intel CPUで作業している。
CLI(clear interrupt flag)はそのまま
SEIはSTI(set interrupt flag)に変更。

なお、別作業でVisual Cでもコンパイルしている。そちらの修正も合わせて記載。
