From f4570ebd836363dc7722b8eb8d099b311021af13 Mon Sep 17 00:00:00 2001 From: Samuel Zeter Date: Wed, 29 Nov 2023 15:17:42 -0700 Subject: x86/tools: objdump_reformat.awk: Allow for spaces GNU objdump and LLVM objdump have differing output formats. Specifically, GNU objump will format its output as: address:hex, whereas LLVM objdump displays its output as address:hex. objdump_reformat.awk incorrectly handles this discrepancy due to the unexpected space and as a result insn_decoder_test fails, as its input is garbled. The instruction line being tokenized now handles a space and colon, or tab delimiter.
