[PATCH v1] RISC-V: XFail the signbit-5 run test for RVV

[PATCH v1] RISC-V: XFail the signbit-5 run test for RVV

[pan2.li]

From: Pan Li <pan2.li@intel.com>

This patch would like to XFail the signbit-5 run test case for
the RVV.  Given the case has one limitation like "This test does not
work when the truth type does not match vector type." in the beginning
of the test file.  Aka, the RVV vector truth type is not integer type.

The target board of riscv-sim like below will pick up `-march=rv64gcv`
when building the run test elf. Thus, the RVV cannot bypass this test
case like aarch64_sve with additional option `-march=armv8-a`.

  riscv-sim/-march=rv64gcv/-mabi=lp64d/-mcmodel=medlow

For RVV, we leverage dg-xfail-run-if for this case like `amdgcn`.

The signbit-5.c passed test with below configurations.

* riscv-sim/-march=rv64gcv/-mabi=lp64d/-mcmodel=medlow

But isn't that just going to turn this into an XPASS when vector is not 
enabled?

Looking at a recent rv64gc run of mine:

Ideally we'd find a way to handle with and without vector.

Thanks all for comments, will have a try for riscv_v and send V2 if everything goes well.

[PATCH v2] RISC-V: XFail the signbit-5 run test for RVV

[pan2.li]

From: Pan Li <pan2.li@intel.com>

This patch would like to XFail the signbit-5 run test case for
the RVV.  Given the case has one limitation like "This test does not
work when the truth type does not match vector type." in the beginning
of the test file.  Aka, the RVV vector truth type is not integer type.

The target board of riscv-sim like below will pick up `-march=rv64gcv`
when building the run test elf. Thus, the RVV cannot bypass this test
case like aarch64_sve with additional option `-march=armv8-a`.

  riscv-sim/-march=rv64gcv/-mabi=lp64d/-mcmodel=medlow

For RVV, we leverage dg-xfail-run-if for this case like `amdgcn`.

The signbit-5.c passed test with below configurations but we need
further investigation for the failures of other configurations.
