Description Jan Kratochvil 2011-04-27 18:32:48 UTC 
typedef int int_typedef;
void f (int_typedef x) {}

gcc -c -g

./gdb-clean -q -nx ./1.o -ex "complete b 'f(" -ex q
b 'f(int)

./gdb-clean -readnow -q -nx ./1.o -ex "complete b 'f(" -ex q
b 'f(int)
b 'f(int_typedef)

-readnow should never affect GDB user visible behavior.
Comment 1 Jan Kratochvil 2011-04-28 16:51:00 UTC 
The dependency on CU expansion is a physname regression.
But the feature of originally-typed-parameters symbols was not present before physname at all.

+ prephysname
b 'f(int)
+ prephysname -readnow
b 'f(int)

+ physname
b 'f(int)
+ physname -readnow
b 'f(int)
b 'f(int_typedef)

+ HEAD
b 'f(int)
+ HEAD -readnow
b 'f(int)
b 'f(int_typedef)
