Description
Right now we have no good observability for the the extended register sets. This implementation follows the outline in IPD 38 and makes a number of changes beyond just the basic format here:
- Makes it so the various
proc_service(3PROC)versions of functions and libc_db/threaddb are no-longer x86 specific - Fixes up the libproc interfaces to make them deal with variable sizing and sets the stage on future platforms that don't have this functionality
- Consolidates the x86
::fpregsimplementation to a common one that leads with the xregs based data - Adds the missing, but documented, error for
ps_lgetxregs(3PROC)family of functions ofPS_NOXREGS. - Adds test suites to cover this, taking into account x86 varies.
