- Subject: FYI the `register' gcc-4.4 change (GCC PR debug/39485)
as I made a note about it in the confcall:
Summary: Explicit `register' keyword started working even during -O0 for
g++-4.4. It makes methods of objects marked by `register' not debuggable.
(gdb) p v.method()
Address requested for identifier "v" which is in register $rbx
It turned for GDB:
-PASS: gdb.cp/classes.exp: calling method for small class
+XFAIL: gdb.cp/classes.exp: calling method for small class (PRMS 2972)
Jakub already checked-in to GCC a fix although one could (less well)
workaround it by some:
# define register
Anyway Jakub already did code it and it should have no disadvantages so
probably there is nothing left to decide about some compromise.
