[OK]Constant folding efficiency.
Posted: 27 Jul 2008 09:13
Hi,
Only for your info:
Apparently this code is compiled more efficient (less rom)
than this one:
Declaring "Ord('A') - 10" as an actual constant does the constant folding, using "Ord('A') - 10" directly in the code does not perform constant folding. Observed in the assembly code.
MicroPascal version 8.0.0.1, PIC = 16F628A.

Code: Select all
const __HexOffset = Ord('A') - 10;
...
Tmp := Tmp + __HexOffset;Code: Select all
Tmp := Tmp + Ord('A') - 10;Declaring "Ord('A') - 10" as an actual constant does the constant folding, using "Ord('A') - 10" directly in the code does not perform constant folding. Observed in the assembly code.
