RISC-V multilib testing is currently busted with follow splat all over: | Schedule of variations: | riscv-sim/-march=rv64imafdc/-mabi=lp64d/-mcmodel=medlow | riscv-sim/-march=rv32imafdc/-mabi=ilp32d/-mcmodel=medlow | riscv-sim/-march=rv32imac/-mabi=ilp32/-mcmodel=medlow | riscv-sim/-march=rv64imac/-mabi=lp64/-mcmodel=medlow ... ... | ERROR: tcl error code NONE | ERROR: torture-init: torture_without_loops is not empty as expected causing insane amount of false failures. | ========= Summary of gcc testsuite ========= | | # of unexpected case / # of unique unexpected case | | gcc | g++ | gfortran | | rv64imafdc/ lp64d/ medlow | 5421 / 4 | 1 / 1 | 6 / 1 | | rv32imafdc/ ilp32d/ medlow | 5422 / 5 | 3 / 2 | 6 / 1 | | rv32imac/ ilp32/ medlow | 391 / 5 | 3 / 2 | 43 / 8 | | rv64imac/ lp64/ medlow | 5422 / 5 | 1 / 1 | 43 / 8 | The error splat itself is from recent test harness improvements for stricter checks for torture-{init,finish} pairing. But the real issue is a latent bug from 2009: commit 3dd1415dc88, ("i386-prefetch.exp: Skip tests when multilib flags contain -march") which added an "early exit" condition to i386-prefetch.exp which could potentially cause an unpaired torture-{init,finish}. The early exit only happens in a multlib setup using -march in flags which is what RISC-V happens to use, hence the reason this was only seen on RISC-V multilib testing. Moving the early exit outside of torture-{init,finish} bracket reinstates RISC-V testing. | rv64imafdc/ lp64d/ medlow | 3 / 2 | 1 / 1 | 6 / 1 | | rv32imafdc/ ilp32d/ medlow | 4 / 3 | 3 / 2 | 6 / 1 | | rv32imac/ ilp32/ medlow | 3 / 2 | 3 / 2 | 43 / 8 | | rv64imac/ lp64/ medlow | 5 / 4 | 1 / 1 | 43 / 8 | gcc/testsuite: * gcc.misc-tests/i386-prefetch.exp: Move early return outside the torture-{init,finish} Signed-off-by: Vineet Gupta <vineetg@rivosinc.com> --- gcc/testsuite/gcc.misc-tests/i386-prefetch.exp | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-)
