Substitutes inline code for calls to built-in function alloca.
>>- -ma--------------------------------------------------------><
If #pragma alloca is unspecified, or if you do not use -ma, alloca is treated as a user-defined identifier rather than as a built-in function.
This option does not apply to C++ programs. In C++ programs, you must include the header malloc.h to include the alloca function declaration.
To compile myprogram.c so that calls to the function alloca are treated as inline, enter:
xlc myprogram.c -ma
