Re: [PATCH 05/27] S390: configure check for vector instruction support in assembler.


the new z13 locghie instruction was introduced in a different commit ( than the other used vector instructions.
Thus i'm now checking for vistrbs and locghie.
The changelog remains the same.

The S390 specific test checks if the assembler has support for the new z13
vector instructions by compiling a vector instruction. The .machine and
.machinemode directives are needed to compile the vector instruction without
-march=z13 option on 31/64 bit.
On success the macro HAVE_S390_VX_ASM_SUPPORT is defined. This macro is used
to determine if the optimized functions can be build without compile errors.
If the used assembler lacks vector support, then a warning is dumped while
configuring and only the common code functions are build.

The z13 instruction support was introduced in
"[Committed] S/390: Add support for IBM z13."


	* (HAVE_S390_VX_ASM_SUPPORT): New macro undefine.
	* sysdeps/s390/ Add test for S390 vector instruction
	assembler support.
	* sysdeps/s390/configure: Regenerated.
