Next: Alpha Built-in Functions, Up: Target Builtins
These built-in functions are available for the Altera Nios II family of processors.
The following built-in functions are always available. They all generate the machine instruction that is part of the name.
int __builtin_ldbio (volatile const void *) int __builtin_ldbuio (volatile const void *) int __builtin_ldhio (volatile const void *) int __builtin_ldhuio (volatile const void *) int __builtin_ldwio (volatile const void *) void __builtin_stbio (volatile void *, int) void __builtin_sthio (volatile void *, int) void __builtin_stwio (volatile void *, int) void __builtin_sync (void) int __builtin_rdctl (int) void __builtin_wrctl (int, int)
The following built-in functions are always available. They
all generate a Nios II Custom Instruction. The name of the
function represents the types that the function takes and
returns. The letter before the n
is the return type
or void if absent. The n
represnts the first parameter
to all the custom instructions, the custom instruction number.
The two letters after the n
represent the up to two
parameters to the function.
The letters reprsent the following data types:
<no letter>
void
for return type and no parameter for parameter types.
i
int
for return type and parameter type
f
float
for return type and parameter type
p
void *
for return type and parameter type
And the function names are:
