We need ChangeLog entries and copyright assignments, but don't use
Signed-off-by.
OK !

I don't think this belongs here. If it does you'll need to explain
further.
Right - that was a local change which seeped out. Now removed.

As a new port, of course use GLIBC_2.26 for minimum symbol version (or
GLIBC_2.27 if that's when it gets in, etc.), and so for any port-specific
symbols.
Done !

This is the default, so you shouldn't need your kernel-features.h file.
Now removed.

These ABI lists are in the old format. You need to regenerate them anyway
for the increased minimum symbol version.
OK !

Should be 2.26 (or later). Consider using an architecture-specific
dynamic linker name as various other architectures do.
OK ! FWIW, this also ties into gcc defined GLIBC_DYNAMIC_LINKER which needs a
pairing change as well.

I'd expect includes of bits/types/sigset_t.h and bits/types/stack_t.h like
other versions, but not of signal.h.
Yeah I see that you recently did sweeping changes to same effect. Noted and
updated.
+typedef struct sigcontext mcontext_t;
You can avoid this problematic definition for a new architecture, even
while we're still discussing eliminating it for existing architectures.
So just use struct sigcontext as data type for uc_mcontext ?
+/* Userlevel context. */
+typedef struct ucontext
+ {
+ unsigned long uc_flags;
+ struct ucontext *uc_link;
This is now struct ucontext_t.
Ah I see this was done yesterday on up/master - ok will do !
Thx for taking a quick first pass at the code and providing the comments.
