gdb: fixing gdb 7.4.1 build with eglibc-2_16
gdb 7.4.1 fails with the following error gdb-7.4.1/gdb/linux-nat.h:79:18: error: field 'siginfo' has incomplete type because gdb use 'struct siginfo' instead of 'struct siginfo_t'. Crosstool-NG allready use the patches to prevent this error so use this patches for buildroot too. see also http://permalink.gmane.org/gmane.comp.gcc.cross-compiling/15305 Fixes http://autobuild.buildroot.net/results/b894a5cecd9c5e0a1a751ebbff90a14aea1803da/build-end.log Signed-off-by: Carsten Schoenert <c.schoenert@gmail.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

Subject: [PATCH] struct siginfo vs. siginfo_t
|
||||
|
||||
gdb/
|
||||
* amd64-linux-nat.c (amd64_linux_siginfo_fixup): Use siginfo_t instead
|
||||
of struct siginfo.
|
||||
* arm-linux-nat.c (arm_linux_stopped_data_address): Likewise.
|
||||
* ia64-linux-nat.c (ia64_linux_stopped_data_address): Likewise.
|
||||
* linux-nat.c (linux_nat_siginfo_fixup, siginfo_fixup)
|
||||
(linux_xfer_siginfo, linux_nat_set_siginfo_fixup)
|
||||
(linux_nat_get_siginfo): Likewise.
|
||||
* linux-nat.h (struct lwp_info, linux_nat_set_siginfo_fixup)
|
||||
(linux_nat_get_siginfo): Likewise.
|
||||
* linux-tdep.c (linux_get_siginfo_type): Likewise.
|
||||
* ppc-linux-nat.c (ppc_linux_stopped_data_address): Likewise.
|
||||
* procfs.c (gdb_siginfo_t): Likewise.
|
||||
|
||||
gdbserver/
|
||||
* linux-arm-low.c (arm_stopped_by_watchpoint): Use siginfo_t instead of
|
||||
struct siginfo.
|
||||
* linux-low.c (siginfo_fixup, linux_xfer_siginfo): Likewise.
|
||||
* linux-x86-low.c (x86_siginfo_fixup): Likewise.
|
||||
* linux-low.h: Include <signal.h>.
|
||||
(struct siginfo): Remove forward declaration.
|
||||
(struct linux_target_ops) <siginfo_fixup>: Use siginfo_t instead of
|
||||
struct siginfo.
