| Using the GNU Compiler Collection (GCC): SPU Function Attributes |
|---|
Next: Symbian OS Function Attributes, Previous: SH Function Attributes, Up: Function Attributes [Contents][Index]
These function attributes are supported by the SPU back end:
naked
This attribute allows the compiler to construct the
requisite function declaration, while allowing the body of the
function to be assembly code. The specified function will not have
prologue/epilogue sequences generated by the compiler. Only basic
asm statements can safely be included in naked functions
(see Basic Asm). While using extended asm or a mixture of
basic asm and C code may appear to work, they cannot be
depended upon to work reliably and are not supported.
