Operator precedence changes
Here is a summary of recent DWScript changes, the major one is a change in operator precedence to something similar to Delphi and FreePascal.
Other changes are related to sets and bug fixes.
String Hashing Shootout
Following a recent post by A. Bouchez about an optimized CRC32 hash, I took it as an opportunity to re-run a small String Hashing Shootout on the worst hash function collision torture test I know: ZIP codes in UTF-16 (Delphi’s default String format).
DWScript happenings and new logo
Long time, no post here, but not no happenings on the DWScript front 🙂
Behold a “cleaned up old logo” for DWScript, which will replace the old one until a better one is made
Delphi XE6 32bits and Scimark
In a Google+ comment to my recent article about inlining in XE6, Leif Uneus posted results from Scimark.
It appears that XE6 is about 30% slower than previous versions at least from XE5 to XE for 32bits floating point.
Note that Scimark does not make use of inlining, but does make heavy use of floating-point computations, loops and arrays.
Edit: issue discussed here was reported in QC 124652 (now marked as resolved)

A Look at Improved Inlining in Delphi XE6
First noticed by dewresearch, Delphi XE6 introduced a new optimization for inlined functions that return a floating-point value.
Here is an exploration of what was improved… and what was not improved.
