We are gradually adopting the specification, notingthat the tags are considered only advisory and do not, in any way,superceed or replace the license texts.

Thankfully, this one issolved by a simple 'make world'. The signalcontext function was goingto the trouble of generating an even 16 byte alignment, but in fact itneeded to be odd aligned to simulate the 8-byte return address havingbeen pushed by the caller. This fixes yet another group of crashes inapplications using libpthread. And yet again, it was my fault all along.While here, rename the duplicate internal ctx_wrapper() functions tomakectx_wrapper() and sigctx_wrapper() so that traces aren't ambiguous.

C code expects that the push of thereturn address disturbed the 16 byte alignment and it will take correctivemeasures to fix it before making another call. Of course, if its wrongto start with, then all hell breaks loose. Essentially we "fix" thisby making the stack alignment odd to start with.This was one of the things that broke on libkse with apps that usefloating point/varargs/etc.Approved by: re (scottl) List of files: /freebsd-12.1/lib/libc/amd64/gen/makecontext.c Fri, 05 Dec 2003 01:36:44 +0000 Peter Wemm <peter@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-12.1/lib/libc/amd64/gen/makecontext.c#4adc354c Add amd64 versions of makecontext() and signalcontext() neededfor libkse (makecontext() is also needed for libthr).These probably will need some tweaking.
