SHA-3 ad hoc compiler: Reloaded

count_the_monkeysIt occurred to me that SHA-3 being a cryptographic hash, it is one of those peculiar bits of code that are fully self-testing. Any bug in a cryptographic hash will quickly cascade to a different result, no matter the bug or the input.

This means the ad-hoc-compiler-monkey can be unleashed “safely”, and can be allowed to try “improper changes.”

Delphi XE6 32bits and Scimark

8087In 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)
