While working on greenlet and fixing switch-related problems, I found that I cornered myself into the same issue with gcc (as opposed to llvm-gcc used on OS X Lion). It seems that for whatever reasons gcc doesn't allow clobbering rbp when it's using it for referencing stack frame. Coincidentally I managed to find a way to correctly save rbp (as well as csr and cw), that works and compiles both with and without -fomit-frame-pointers. In anyone is interested you can find my slp_transfer for amd64 here: https://bitbucket.org/snaury/greenlet/src/5d37cde9474c/platform/switch_amd64_unix.h If anyone can verify it's 100% correct (though redundant), then you can maybe use it in stackless too. _______________________________________________ Stackless mailing list [email protected] http://www.stackless.com/mailman/listinfo/stackless
