Subject: Delete JIT disasm output in test wrappers before running FileCheck (#81538)
X-Git-Tag: accepted/tizen/unified/riscv/20231226.055536~4262
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2411d09d80a3a419f4d3b8754f3fde98bf11d144;p=platform%2Fupstream%2Fdotnet%2Fruntime.git

Delete JIT disasm output in test wrappers before running FileCheck (#81538)

JitStdOutFile has append behavior, so if you rerun the scripts you would
get multiple repeated sets of jitdisasm. This would give FileCheck a
much range of disassembly to match that was much wider than expected.
