Subject: Re: [RFC] Native TLS for globals in ZTS
From: arnaud.lb@gmail.com (Arnaud Le Blanc)

Hi,

I updated the RFC.

I added benchmark tests on x86_64: Position independent code is the default 
there and is as fast as non-PIC on IA-32. The initial patch using dynamic TLS 
gives the same results as on IA-32 with static TLS.

I also tested the patch (with a few changes) on Windows Server 2008 with IIS 
(older Windows cannot use TLS in LoadLibrary()-loaded DLLs). This works as 
expected, but there are still some restrictions.

Regards,

Arnaud
