* gdb.texinfo (Implementing a Remote Stub): Explain that you
should transfer control to the stub in the startup code instead of
in main. Mention the need to get past the initial breakpoint.
* elfcode.h (elf_checksum_contents): Read in the section's
contents if they are not already available.
* compress.c (bfd_get_full_section_contents): Use zmalloc to
allocate the buffers so that excess bytes are guaranteed to be
zero.

The ada-lang module was using a static global called "exception_info"
for all inferiors. But each inferior might be different, and thus
this patch makes this data per-inferior.
gdb/ChangeLog:
* ada-lang.c (struct ada_inferior_data) [exception_info]:
New field.
(exception_info): Delete.
(ada_exception_support_info_sniffer): Get exception_support_info
data from our per-inferior data. Adjust code accordingly.
(ada_unhandled_exception_name_addr_from_raise): Likewise.
(ada_exception_name_addr_1, ada_exception_sym_name): Ditto.
(ada_executable_changed_observer): Delete.
(_initialize_ada_language): Remove call to
observer_attach_executable_changed.
This patch should help the user understand why the debugger is not
able to insert Ada exception catchpoints when the Ada runtime was
stripped of debugging info, as is often the case on many GNU/Linux
distros:
(gdb) catch exception
Your Ada runtime appears to be missing some debugging information.
Cannot insert Ada exception catchpoint in this configuration.
gdb/ChangeLog:
* ada-lang.c (ada_has_this_exception_support): Raise an error
if we could find the Ada exception hook in the Ada runtime,
but no debugging info for that hook.
gdb/testsuite/ChangeLog:
* gdb.ada/catch_ex.exp, gdb.ada/mi_catch_ex.exp: Adjust
expected output for unsupported case.
This patch cleans up a bit the way we detect which type of runtime
the program uses with respect to Ada exceptions. It also removes
an unnecessary check in ada_exception_sal which is already performed
by ada_exception_support_info_sniffer.
Some of the changes are preparation work for detecting the situation
where the Ada runtime is found, but lacking debugging info.
gdb/ChangeLog:
* ada-lang.c (ada_has_this_exception_support): New function,
extracted out of ada_exception_sal and ada_exception_sal.
(ada_exception_support_info_sniffer): Simplify by using
ada_has_this_exception_support.
(ada_exception_sal): Replace unnecessary checks by assertions.
Minor simplifications.
* elf32-hppa.c (final_link_relocate): Convert R_PARISC_TLS_GD21L,
R_PARISC_TLS_LDM21L and R_PARISC_TLS_IE21L relocations to
R_PARISC_DPREL21L when not doing a shared link. Likewise convert
R_PARISC_TLS_GD14R, R_PARISC_TLS_LDM14R and R_PARISC_TLS_IE14R to
R_PARISC_DPREL14R. Handle R_PARISC_TLS_GD21L, R_PARISC_TLS_LDM21L
and R_PARISC_TLS_IE21L with R_PARISC_DLTIND21L.
* elfxx-mips.c (mips_elf_link_hash_table.rld_value): Remove.
(mips_elf_link_hash_table.rld_symbol): New field;

in rld_symbol.
(_bfd_mips_elf_size_dynamic_sections): Set correct size for .rld_map.
(_bfd_mips_elf_finish_dynamic_symbol): Remove .rld_map handling.
(_bfd_mips_elf_finish_dynamic_sections): Use rld_symbol to

quit initializing rld_value.
