Error Messages
builtin_divmodud (Continued)
builtin_divsd
builtin_divud
builtin_dmaoffset
None.
Computes the quotient num / den. A math error exception occurs if den
is zero. Function arguments are signed, as is the function result. The
command-line option -Wconversions can be used to detect unex-
pected sign conversions.
int __builtin_divsd(const long num, const int den);
num numerator
den denominator
Returns the signed integer value of the quotient num / den.
div.sd
Computes the quotient num / den. A math error exception occurs if den
is zero. Function arguments are unsigned, as is the function result. The
command-line option -Wconversions can be used to detect unex-
pected sign conversions.
unsigned int __builtin_divud(const unsigned
num numerator
den denominator
Returns the unsigned integer value of the quotient num / den.
div.ud
Obtains the offset of a symbol within DMA memory.
For example:
Might generate:
unsigned int __builtin_dmaoffset(const void *p);
*p
Returns the offset to an accumulator.
dmaoffset
An error message will be displayed if the result is not an accumulator
register.
long num, const unsigned int den);
unsigned int result;
char buffer[256] __attribute__((space(dma)));
result = __builtin_dmaoffset(&buffer);
mov #dmaoffset(buffer), w0
