Hi all,
Also did some quick experiments, the results are:
test_snipped = 0, Code 15, data 3
test_snipped = 1, Code 21, data 3
test_snipped = 2, Code 16, data 3
So by writing two explicit if statements can help a lot (difference is
even more dramastic when changing an if ( x and y ) evalutation by an
If x followed by an if y statement. Seems that the compiler can be
improved quite a bit on the expression evalution

include 16f628
const test_snipped = 0
forever loop
if test_snipped == 0 then
if ( (RCSTA & 0x11) != 0 ) then
PORTA = 0xFF
end if
end if
if test_snipped == 1 then
if ((RCSTA_OERR == TRUE) | (RCSTA_FERR == TRUE)) then
PORTA = 0xFF
end if
end if
if test_snipped == 2 then
var bit tst_bit = false
if ((RCSTA_OERR == TRUE) ) then tst_bit = true end if
if ((RCSTA_FERR == TRUE) ) then tst_bit = true end if
if tst_bit then
PORTA = 0xFF
end if
end if
end loop
