@ -3624,14 +3624,13 @@ For Solaris 2.3 and later, the linker ignores relocations for the stabs
section. The value of a @code{N_FUN} stab is zero and the address of a
function can be obtained from the ELF (non-stab) symbols. Sun, in
reference to bug 1142109, has verified that this is intentional.
Because looking things up in the ELF symbols is slow and GDB currently
only has code to do this for functions (which is enough for Solaris
since read-only variables go in the @code{.rodata} section), it would
probably be better to use a @code{Ttext.text} symbol for stabs-in-elf on
non-Solaris machines, and make the address in the @code{N_FUN} relative
to the @code{Ttext.text} symbol. In addition to @code{N_FUN} symbols,
whether the linker relocates stabs also affects some @code{N_ROSYM},
@code{N_STSYM}, and @code{N_LCSYM} symbols; see @ref{Statics}.
