Hi,the new z13 locghie instruction was introduced in a different commit (https://sourceware.org/ml/binutils/2015-03/msg00088.html) than the other used vector instructions.
Thus i'm now checking for vistrbs and locghie. The changelog remains the same. Bye Stefan On 07/03/2015 03:38 PM, Stefan Liebler wrote:
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." (https://sourceware.org/ml/binutils/2015-01/msg00197.html) ChangeLog: * config.h.in (HAVE_S390_VX_ASM_SUPPORT): New macro undefine. * sysdeps/s390/configure.ac: Add test for S390 vector instruction assembler support. * sysdeps/s390/configure: Regenerated.
