h_iabs
SYNTAX
FUNCTION
DESCRIPTION
signed integer; the result is an unsigned integer. This operation requires a zero as first argument. The programmer is
advised to use the
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
EXAMPLES
A-69
r30 = 0xffffffff
r10 = 0, r40 = 0xfffffff4
r20 = 1, r40 = 0xfffffff4
r50 = 0x80000001
r60 = 0x80000000
r20 = 1

operation computes the absolute value of rsrc2 and stores the result into rdest. The argument is a
operation optionally takes a guard, specified in rguard. If a guard is present, its LSB controls the
