Issue with new Compiler update

[David Barker]

OK, I've uploaded a new BETA (B4)

http://www.sfcompiler.co.uk/downloads/beta/

This should fix the math problem. I've also identified a problem with for...next termination when using shortint. This should also now be fixed. Let me know how it goes...

B4 seems to fix those issues, but in going back through some of the recent test cases at some point a previous fix was undone/rebroke.
Both this case and the original, longer test case fail now (I think they were the same issue if I remember correctly). Here's the short one...

Code: Select all

{
 I diluted it further to this program:
That is, failed addition where S16 + S16 -> S32.  
This would cause the WRITE and IF statements to fail. 
Casting to integer results in S16 + S16 -> S16 which doesn't (appear to) 
have the same problem.
}
Device = 18F25K22
Clock = 64

#option _showvar = true

// standard SF routines
Include "convert.bas"
Include "usart.bas"

Dim a As Integer
Dim array1(135) As Byte  ' 134 is ok, larger number and addition fails
Dim b As Integer
Dim res As LongInt

' link in array...
array1(0) = 0

' set all digital...
ANSELA = 0
ANSELB = 0
ANSELC = 0
USART.SetBaudrate(br38400)

' add two integer (S16) to longint (S32) - Changing array1() will push
' the variables into different banks causing the addition to fail
a = 10
b = -20
res = a + b
usart.write(dectostr(res),13,10)

Try installing the latest update

and let me know if it fixes the error for you.

The new version worked for me w/all the tests I tried... hopefully it'll do the same for everybody else.

Thanks for all the effort.

Thanks for the feedback Jerry...
