From f1733a1d3cd32a9492f4cf866be37bb46e10163d Mon Sep 17 00:00:00 2001 From: Qian Cai Date: Fri, 14 Dec 2018 14:17:20 -0800 Subject: checkstack.pl: fix for aarch64 There is actually a space after "sp," like this, ffff2000080813c8: a9bb7bfd stp x29, x30, [sp, #-80]! Right now, checkstack.pl isn't able to print anything on aarch64, because it won't be able to match the stating objdump line of a function due to this missing space. Hence, it displays every stack as zero-size. After this patch, checkpatch.pl is able to match the start of a function's objdump, and is then able to calculate each function's stack correctly.

To avoid that, always open files in binary mode and decode line-by-line, ignoring encoding errors. One tricky case is when piping data into the script and reading it from standard input. By default, standard input will be opened in text mode, so we need to reopen it in binary mode. The breakage only happens with python3 and results in a UnicodeDecodeError (according to Uwe).
