Re: [PATCH] Fix outputting of debug info for things marked *INTERNAL* (fwd)


Hello gcc-patches,

What's the status of Jason Merrill's patch below?

I'm working on fixing the gdb testsuite for the g++ v3 abi.  One of the
problems is that g++ emits "*INTERNAL*" symbols which do not correspond
to any actual code.  Here's a sample.

  .stabs  "A:T(0,25)=s4x_:/0(0,1),0,32;operator=::(0,26)=#(0,25),(0,27)=&(0,25),(0,28)=*(0,25),(0,29)=&(0,25),(0,21);:_ZN1AaSERKS_;2A.;A::(0,30)=#(0,25),(0,21),(0,28),(0,29),(0,21);:_ZN1AC1ERKS_ *INTERNAL* ;2A.;__base_ctor::(0,30):_ZN1AC2ERKS_;2A.;__comp_ctor::(0,30):_ZN1AC1ERKS_;2A.;A::(0,31)=#(0,25),(0,21),(0,28),(0,1),(0,21);:_ZN1AC1Ei *INTERNAL* ;2A.;__base_ctor::(0,31):_ZN1AC2Ei;2A.;__comp_ctor::(0,31):_ZN1AC1Ei;2A.;;",128,0,0,0

These *INTERNAL* symbols show up in gdb when the user inspects the type
("ptype A").  I need them to not show up, one way or another.

Jason Merrill wrote a patch to remove them from gcc's output, but the
patch doesn't appear to be in either gcc-3_0-branch or mainline.

So, can gcc remove these symbols from its output?  If not, I'll look
into making gdb's input reader skip them.

How about this?
