Hi, I read in the mailing list archives that some work was done on the area of implementing native TLS support and I'm interested in continuing it, in case nobody is currently on it.
My initial goal would be to have an implementation that would be both thread-model agnostic (i.e. be both sufficient and compatible with current posix & win32 gcc thread models), leveraging the current dependency on gthreads (and the consequent libpthread one in case of the posix thread model). For that I thought about patching gcc to generate native TLS compatible with win32/msvc semantics. Or, if that's too hard, at least provide a better emulation (perhaps using TlsAlloc() & friends), preferably one that doesn't rely on mutexes. But I don't want to go to deep without information from those who attempted something like that in the past. I'm currently awaiting for feedback from fsf on my papers, but a small amount of work (perhaps for early testing) can be early released accordingly to fsf statements in the form of small patches, should that be needed / convenient. A further goal would be to investigate this report and fix it if possible (and if not fixed as a side effect of the planned ork): https://sourceforge.net/p/mingw-w64/bugs/445/ Cheers, Alexandre
