Subject: Fix siginfo C++ build error
X-Git-Tag: gdb-7.11-release~40
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8adce0342f5f50aba0154fc56ca59df45b219738;p=external%2Fbinutils.git

Fix siginfo C++ build error

Change the signature of gdbserver's siginfo_fixup functions so that it's
in line with gdb's.  This gets rid of the following build error in C++:

  /home/emaisin/src/binutils-gdb/gdb/gdbserver/linux-x86-low.c: In function ‘int x86_siginfo_fixup(siginfo_t*, void*, int)’:

gdb/gdbserver/ChangeLog:

	* linux-aarch64-low.c (aarch64_linux_siginfo_fixup): Change
	void * to gdb_byte *.
	* linux-low.c (siginfo_fixup): Likewise.
	(linux_xfer_siginfo): Likewise.
	* linux-low.h (struct linux_target_ops) <siginfo_fixup>:
	Likewise.
	* linux-x86-low.c (x86_siginfo_fixup): Likewise.
