So far the gnu_vector test was limited to "static" aspects of GDB's vector support, like evaluating vector-valued expressions. This patch enriches the test and adds checks for GDB's vector ABI support as well. The new checks particularly verify inferior function calls with vector arguments and GDB's handling of vector return values. The test now attempts to compile for the target's "native" architecture, such that a hardware vector ABI is used if available. Since GDB has no vector ABI support for x86 and x86_64 targets, most of the new checks are KFAILed there. gdb/testsuite/ChangeLog: * gdb.base/gnu_vector.c: Include stdarg.h and stdio.h. (VECTOR): New macro. Use it... (int4, uint4, char4, float4, int2, longlong2, float2, double2): ...for these typedefs. (int8, char1, int1, double1): New typedefs. (struct just_int2, struct two_int2): New structures. (add_some_intvecs, add_many_charvecs, add_various_floatvecs) (add_structvecs, add_singlevecs): New functions. (main): Call add_some_intvecs twice. * gdb.base/gnu_vector.exp: Drop GCC version check; just attempt the compile and exit upon failure. Try compiling for the "native" architecture. Test inferior function calls with vector arguments and vector return value handling with "finish" and "return".
