Hi, I have got the following error (see below, with a lot of other compiler warnings) when trying to compile pypy with the '--shared' option during the last stop (compile_c). I've seen similar issues without --shared before and it was solved by setting the CFLAGS to -O1 but that doesn't seem to help this time. Is it possible to fix this?

Ah, that's yet another asmgcc issue. Probably shows up with gcc 4.9. Can you send me privately (or on a site like http://bpaste.net/ ) the .s file given as argument to the call to trackgcroot.py? (It's the one that includes "rex64" in it.) A bientôt, Armin.

I grep'ed the /tmp/usession-default-*/ directory and find 3 .s files with rex64 in it. Here is one of them[1], with the corresponding c file[2]. Hope these can help. =) Yichao Yu [1] http://bpaste.net/show/437121/ [2] http://bpaste.net/show/437127/

Actually the problem is gone when adding option --gcrootfinder=shadowstack, which also seems to be necessary when building the py3k branch with --shared. I guess this is what you mean by "yet another asmgcc issue"? On Sat, Jul 5, 2014 at 5:55 PM, Yichao Yu <yyc1992@gmail.com> wrote:

Yes. Here, as is often the case, the matter is easily resolved. I checked in 85672cabac67, which should fix it. A bientôt, Armin.
