[PATCH] PowerPC: Add systemtap static probe points in setjmp/longjmp

From: Adhemerval Zanella <azanella at linux dot vnet dot ibm dot com>
To: "GNU C. Library" <libc-alpha at sourceware dot org>

Subject: [PATCH] PowerPC: Add systemtap static probe points in setjmp/longjmp
Authentication-results: sourceware.org; auth=none
Hi all,

This patch add static probes for setjmp/longjmp in the way gdb expects. Along with
another fix (discussed at https://sourceware.org/ml/gdb/2013-10/msg00191.html) this
fixes the gdb.base/longjmp.exp gdb testcases.

I have to change the symbol_name and use macros to change them to avoid change the
probe names and ending up adding more logic on GCC (since with the expected name
GDB work seamlessly). They symbols name will be the same as before.

Tested on PPC64, PPC32, and PPC32 soft-fp.

2013-10-31  Adhemerval Zanella  <azanella@linux.vnet.ibm.com>

	* sysdeps/powerpc/powerpc32/__longjmp-common.S: Add "longjmp" and
	"longjmp_target" static probes.
	(__longjmp): Rename to __longjmp_symbol.
	* sysdeps/powerpc/powerpc32/fpu/__longjmp-common.S: Likewise.
	* sysdeps/powerpc/powerpc32/__longjmp.S: Define __longjmp_symbol based
	on which longjmp to generate.
	* sysdeps/powerpc/powerpc32/fpu/__longjmp.S: Likewise.
	* sysdeps/powerpc/powerpc32/fpu/setjmp-common.S: Add "setjmp" static
	probe.
	(__sigsetjmp): Rename to __sigsetjmp_symbol.
	(__sigjmp_save): Rename to __sigjmp_save_symbol.
	* sysdeps/powerpc/powerpc32/setjmp-common.S: Likewise.
	* sysdeps/powerpc/powerpc32/fpu/setjmp.S: Define __sigsetjmp_symbol
	and __sigjmp_save_symbol based on which sigsetjmp to generated.
	* sysdeps/powerpc/powerpc32/setjmp.S: Likewise
	* sysdeps/unix/sysv/linux/powerpc/powerpc32/____longjmp_chk.S: Define
	__longjmp_symbol based on which __longjmp to generate.
	* sysdeps/powerpc/powerpc64/setjmp-common.S: Add "setjmp" static
	probe.
	(setjmp): Rename to setjmp_symbol.
	(__sigsetjmp): Rename to __sigsetjmp_symbol.
	(_setjmp): Rename to _setjmp_symbol.
	(__sigsetjmp): Rename to __sigsetjmp_symbol.
	* sysdeps/powerpc/powerpc64/setjmp.S: Define setjmp_symbol,
	_setjmp_symbol, __sigsetjmp_symbol, and __sigjmp_save_symbol based on
	which setjmp to generate.
	* sysdeps/powerpc/powerpc64/__longjmp-common.S: Add "longjmp" and
	"longjmp_target" static probes.
