c0db0690f7fae7bd8cf1493e2f6b2a672e0c0de8 - selftests/riscv: fix compiler output flag spacing in all Makefiles

Sun, 07 Jun 2026 04:17:52 +0200

selftests/riscv: fix compiler output flag spacing in all MakefilesStandardize the compiler output flag format across all RISC-Vselftests by adding a space between '-o' and '$@'.Although '-o$@' is perfectly valid for GCC/Clang to parse,changing it to '-o $@' with a space aligns with the GNUofficial documentation conventions, improves readability byvisually separating the flag from the target variable, andensures consistency with other architectures.Currently, RISC-V selftests use '-o$@' (without space) in 13instances across 6 Makefiles, while all other architecturesconsistently use '-o $@' (with space). This inconsistency makesRISC-V an outlier in the kernel's selftest infrastructure.Signed-off-by: Zong Li Link: https://patch.msgid.link/20260511032917.3542802-1-zong.li@sifive.com[pjw@kernel.org: cleaned up patch description]Signed-off-by: Paul Walmsley List of files: /linux/tools/testing/selftests/riscv/vector/Makefile

selftests: riscv: Fix vector testsOverhaul the riscv vector tests to use kselftest_harness to help thetest cases correctly report the results and decouple the individual testcases from each other. With this refactoring, only run the test cases ifvector is reported and properly report the test case as skippedotherwise. The v_initval_nolibc test was previously not checking ifvector was supported and used a function (malloc) which invalidatesthe state of the vector registers.Signed-off-by: Charlie Jenkins Tested-by: Yangyu Chen Link: https://lore.kernel.org/r/20241113-xtheadvector-v11-12-236c22791ef9@rivosinc.comSigned-off-by: Palmer Dabbelt List of files: /linux/tools/testing/selftests/riscv/vector/Makefile
