Log message:
try ignoring bad PLT entries in ELF symbol tables
Comment says it all:
/* On ia64-hpux, we have discovered that the system linker
adds undefined symbols with nonzero addresses that cannot
be right (their address points inside the code of another
function in the .text section). This creates problems
when trying to determine which symbol corresponds to
a given address.
We try to detect those buggy symbols by checking which
section we think they correspond to. Normally, PLT symbols
are stored inside their own section, and the typical name
for that section is ".plt". So, if there is a ".plt"
section, and yet the section name of our symbol does not
start with ".plt", we ignore that symbol. */
gdb/ChangeLog:
* elfread.c (elf_symtab_read): Ignore undefined symbols with
nonzero addresses if they do not correspond to a .plt section
when one is available in the objfile.
