Re: [golang-dev] Golang and TLS

Hi thanks a lot for your explanations. So we are suposed to load the c-shared so then run the init(). Do we must pass argc, argv to the .so initializer and that all ? Or must we then call GoStart after doing this ? Best regards Benoît On Thu, Sep 1, 2016 at 9:54 PM, David Crawshaw

This is what I saw in the code managing the flags. By anyway I think you are right and shared is an "impasse". On Wed, Aug 31, 2016 at 4:06 PM, Nadav Har'El <n...@scylladb.com> wrote: > > On Wed, Aug 31, 2016 at 4:26 PM, Benoît Canet <ben...@cloudius-systems.com >

Re: [PATCH] syscall: save also %rbp

If you look as the assembly dump of loader.elf you will see save saving rbp and restoring it is usually the first and last thing function do. It marks the begining of a frame. On Mon, Aug 29, 2016 at 12:29 PM, Nadav Har'El wrote: > Not saving and restoring the rbp register

Hi Justin, You should write proper comments below your commit message for the virgin reviewer. Here I have no idea what CPU_COUNT_S is and why you want it. Additional + proper comments in commits message help us build a sound git log history. Best regards Benoît On Thu, Aug 18, 2016 at 12:45

I am not sure I understand your question correctly. Had you used some capstan tutorial previously or the one I pasted you ? Because these ones generate .vmx files that must be what you are looking for. Best regards 2016-08-15 16:26 GMT+02:00 Benoît CANET <ben...@irqsave.net>: > &g
