[PATCH] gfortran testsuite: Remove unit-files in files having open-statements, PR116701

Here's a general approach to handle PR116701. I considered adding manual deletions as quoted below and mentioned in the PR, but seeing the handling of "integer 8" in fortran-torture-execute I decided to follow that example: better scan the source for open-statements than relying on manual annotati

[PATCH] tree-optimization/114855 - high update_ssa time

[PATCH] aarch64: Expand CTZ to RBIT + CLZ for SVE [PR109498]

Currently, we vectorize CTZ for SVE by using the following operation: .CTZ (X) = (PREC - 1) - .CLZ (X & -X) Instead, this patch expands CTZ to RBIT + CLZ for SVE, as suggested in PR109498. The patch was bootstrapped and regtested on aarch64-linux-gnu, no regression. OK for mainline? Signed-off-b
