Do you have more info regarding the AIX assembler bug you are referring to?
PR46072 was about a different assembler bug, it's just someone in that report
have also encountered the stabstring length issue. I

--- Comment #10 from David Edelsohn ---
Stabstring continuations originally seem to have been disabled for AIX XCOFF
because the AIX assembler did not support them correctly. IBM's proprietary
compiler, VAC/XLC, directly generates object files a

xlC generates stubs with continuation, and it seems to cut them at 16k both for
32-bit and 64-bit objects, so maybe gcc could do the same. gdb-7.7.1 seems to
segfault on stubs longer than 32k for 32-bit exec

Thanks for the patch, Zoltan, but the patch is not the challenge. It is not
difficult to instruct GCC to generate stabs with continuation. The question
always has been if the debuggers on AIX can understan

With the above trivial change I've been able to build code with long
stabstrings on AIX 6.1. I was using the gcc-4.8 branch since that's what we are
using here. If you fix this, could you please also apply i

If I manually #undef DBX_CONTIN_LENGTH in dbxout.c before the default in there,
I get:
.stabs
"E:T(0,21)=eEE10:0,EE11:1,EE12:2,EE13:3,\\",128,0,0,0

So are we talking about something like:
#define A(n) EE##n,
#define B(n) A(n##0) A(n##1) A(n##2) A(n##3) A(n##4) \
A(n##5) A(n##6) A(n##7) A(n##8) A(n##9)
#define C(n) B(n##0) B(n##1) B(n##2) B(n##3)

Can you create a small non-gcc testcase that shows the dbxout.c deficiency
please?
