AngelScript 2.23.1 is here

Andreas Jonsson · 2012-05-08T01:05:57

[color=#000000][font=Arial] A new version is here. This release has been mostly focused on performance improvements and bug fixes, so there are not a lot of visible changes.[/font] [color=#000000][font=Arial] Especially the compatibility problems with Mac OS have been fixed. Apple had decided to change their compiler suite in the latest version of Mac OS X, and this made my code that has been working flawlessly for many years to break. As I do not have an up-to-date Mac it took a bit of trial and error to get things working again, but mainly thanks to Matt Bush, from Hitbox Team, who did a lot of testing for me, was I able to correct the problems.[/font] [color=#000000][font=Arial] Much of the performance improvements that has been made has been with the way the bytecode is generated. That together with the introduction of some new bytecode instructions, which replace frequently occurring bytecode sequences, should hopefully give a general performance boost for script execututions. I say hopefully, because it really depends on what your scripts look like.[/font] [color=#000000][font=Arial] Unfortunately the bytecode changes also means that the JIT compiler that Blind Mind Studios released in February needs to be updated before it can be used with this new version of AngelScript.[/font] [color=#000000][font=Arial] I've already contacted them, and they are working on getting the JIT compiler updated, in addition to further enhancements, e.g. support for 64bit Windows. Hopefully they will be able to complete that task soon.[/font] [color=#000000][font=Arial] Regards,[/font][color=#000000][font=Arial] Andreas[/font]

Thanks. That must be the moment the problem was introduced, still I don't understand why this is not happening on my machine. It seems that my project is not equal to what is in the SVN for some reason, but that really shouldn't be possible as I always do diffs to verify differences in all files. I'll investigate further when I get home.

The difference is with the Microsoft SDK version 6.0a. I have version 6.1 installed, which is why I didn't face the problem due to the disabled language extensions.

In version 6.1 Microsoft corrected the problem with the specstrings.h header file by adding the following precompiler condition:





#if defined(_MSC_EXTENSIONS) || defined(_PREFAST_) || defined(OACR)

#define __$adt_prop(adt,prop)               __declspec("SAL_adt("#adt","#prop")")

#define __$adt_add_prop(adt,prop)           __declspec("SAL_add_adt_property("#adt","#prop")")

#define __$adt_remove_prop(adt,prop)        __declspec("SAL_remove_adt_property("#adt","#prop")")

#define __$adt_transfer_prop(arg)           __declspec("SAL_transfer_adt_property_from("#arg")")

#define __$adt_type_props(typ)              __declspec("SAL_post_type("#typ")")

#define __$volatile                         __declspec("SAL_volatile")

#define __$nonvolatile                      __declspec("SAL_nonvolatile")

#define __$possibly_notnulltermiated        __declspec("SAL_RequiresZeroTermination(sometimes)")

#endif

Anyway, I'll re-enable the language extensions in the project settings to avoid this problem for others that use MS SDK 6.0a.

Regards,
Andreas

Heh, turns out despite the fact I had v6.1 installed, v6.0 was still used by MSVC due to some bogus registry value. Thanks for the hint!

Anyway, it was weird to have this setting different for release and debug builds.

I've updated our JIT compiler for 2.23.1.

Should remove header file 'as_bytecodedef.h' in project of MSVC10 to prevent its 'check-file-missing' building ...
