Subject: [PATCH v2 2/2] arch/x86/tools/objdump_reformat.awk: Allow for spaces
Date: Fri, 4 Mar 2022 14:16:11 +1100 [thread overview]
Message-ID: <20220304031611.5763-3-samuelzeter@gmail.com> (raw)
In-Reply-To: <20220304031611.5763-1-samuelzeter@gmail.com>
From: Samuel Zeter <samuelzeter@gmail.com>
objdump and llvm-objdump have differing output formats. Specifically,
objump will format its output as: address:<tab>hex, whereas
llvm-objdump displays its output as address:<space>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.
