- Subject: [rfa] Stabs documentation tweak for pointers to members
When working on pointers to members I encountered only one place in
GDB that seemed to need an actual "member" type, instead of just "pointer to
member" (which is not really a pointer at all). That was in the stabs
reader. The documentation says that stabs has a "member" construct, and
represents pointers to members as pointers to that construct. The reader
code matches this.
But if this was ever the case for GCC, it hasn't been for a while. Now
the @ descriptor means pointer to member. This patch corrects the manual;
the final patch will correct the stabs reader.
OK to commit?
