[fpc-pascal] Efficient String concatenation

[Graeme Geldenhuys]

Hi,

This is a very impressive little blog about efficient string 
concatenation in Delphi. But it also applies to Free Pascal.

     
http://www.delphitools.info/2013/10/28/efficient-string-concatenation-in-delphi/

I created two versions of the small test project and compiled it with 
FPC as follows.

  $ fpc -O2 -al stringtest.pas
  $ fpc -O2 -al stringtest2.pas

Then compared the two *.s assembler files. As the blog mentions, the 
"stupid looking" version generates a heck of a lot less ASM code. Umm. 
:)

Regards,
  - Graeme -
