2008-02-24 Jan Kratochvil <jan.kratochvil@redhat.com>
Port to GDB-6.8pre.
currently for trivial nonthreaded helloworld with no debug info up to -ggdb2 you
will get:
(gdb) p errno
[some error]
* with -ggdb2 and less "errno" in fact does not exist anywhere as it was
compiled to "(*__errno_location ())" and the macro definition is not present.
Unfortunately gdb will find the TLS symbol and it will try to access it but
as the program has been compiled without -lpthread the TLS base register
(%gs on i386) is not setup and it will result in:
Cannot access memory at address 0x8
Attached suggestion patch how to deal with the most common "errno" symbol
for the most common under-ggdb3 compiled programs.
2007-11-03 Jan Kratochvil <jan.kratochvil@redhat.com>
* ./gdb/dwarf2read.c (read_partial_die, dwarf2_linkage_name): Prefer
DW_AT_MIPS_linkage_name over DW_AT_name now only for non-C.

* amd64-linux-nat.c: Support new linux_elfcore_write_prpsinfo,
linux_elfcore_write_prstatus, linux_elfcore_write_prfpreg.
(i386_linux_gregset32_reg_offset): New mapping for i386 on amd64.
* gcore.c (gcore_create_callback): Comment vdso Linux kernel bug.
* configure.ac: Check for <sys/user32.h>, <sys/procfs32.h>.
* configure, config.in: Regenerated.
* gdb_user32.h, gdb_procfs32.h: Define 32-bit core files even for
64-bit gdb, provide fallbacks for <sys/user32.h> and <sys/procfs32.h>.
* linux-nat.c: Virtualize `elfcore_*' by (*`linux_elfcore_*').
(linux_nat_do_thread_registers): Likewise.
(linux_nat_make_corefile_notes): Likewise.
* linux-nat.h: Likewise.
* Makefile.in: Dependencies updated.
2007-10-16 Jan Kratochvil <jan.kratochvil@redhat.com>
Port to GDB-6.7.
2008-02-24 Jan Kratochvil <jan.kratochvil@redhat.com>

* readline/display.c (line_state, line_state_array, line_state_visible,
line_state_invisible): Encapsulate _rl_wrapped_line, inv_lbreaks,
inv_lbsize, vis_lbreaks, vis_lbsize, visible_line, invisible_line.
(init_line_structures): Initialize both _rl_wrapped_line ones now.
(rl_redisplay): Fix _rl_wrapped_line handling by using its own size.
Swap whole `line_state_visible' / `line_state_invisible' structures.
(update_line): Update for new `_rl_wrapped_line'.
