This option divides any -Idirectory options on the command line into two groups. All directories appended to an -I option to the left of -I- are not searched for header files named in angle brackets in an #include directive, such as this one: #include <stdio.h> Instead, they are sear...
比如，下面这行是你的 gcc 命令：gcc -Wall -Wextra -Wfloat-equal test.c -o test 然后你可以把这三个和警告相关的选项放到一个文件里，文件名叫做 gcc-options：$ cat gcc-options -Wall -Wextra -Wfloat-equal这样，你的 gcc 命令会变得更加简洁并且易于管理：gcc @gcc-options test.c -o test ...

Most of the command-line options that you can use with GCC are useful for C programs; when an option is only useful with another language (usually C++), the explanation says so explicitly. If the description for a particular option does not mention a source language, you can use that ...
·New command-line options have been added for the C and C++ compilers: ○ -Wshift-negative-value warns about left shifting a negative value. ○ -Wshift-overflow warns about left shift overflows. This warning is enabled by default. -Wshift-overflow=2 also warns about left-shifting 1 into...
Causes GCC to remember the state of the diagnostics as of eachpush, and restore to that point at eachpop. If apophas no matchingpush, the command-line options are restored. #pragma GCC diagnostic error "-Wuninitialized" foo(a); /* error is given for this one */ ...
