компилятор C и C ++ проекта GNU (GNU project C and C++ compiler)
Параметры подробно (Options detail)
Machine-Dependent
Each target machine supported by GCC can have its own
options---for example, to allow you to compile for a particular
processor variant or ABI, or to control optimizations specific to
that machine. By convention, the names of machine-specific
options start with -m
.
Some configurations of the compiler also support additional
target-specific options, usually for compatibility with other
compilers on the same platform.
