Subject: [PATCH v3] scripts/decodecode: fix faulting instruction no print when opps.file is DOS format
Date: Thu, 30 Sep 2021 10:04:39 +0800 [thread overview]
Message-ID: <20210930020439.3605-1-weidonghui@allwinnertech.com> (raw)
From: weidonghui <weidonghui@allwinnertech.com>
If opps.file is in DOS format, faulting instruction cannot be printed:
/ # ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
/ # ./scripts/decodecode < oops.file
[ 0.734345] Code: d0002881 912f9c21 94067e68 d2800001 (b900003f)
aarch64-linux-gnu-strip: '/tmp/tmp.5Y9eybnnSi.o': No such file
aarch64-linux-gnu-objdump: '/tmp/tmp.5Y9eybnnSi.o': No such file
All code
========
0: d0002881 adrp x1, 0x512000
4: 912f9c21 add x1, x1, #0xbe7
8: 94067e68 bl 0x19f9a8
c: d2800001 mov x1, #0x0 // #0
10: b900003f str wzr, [x1]
Code starting with the faulting instruction
===========================================
Background: The compilation environment is Ubuntu,
and the test environment is Windows.
Most logs are generated in the Windows environment.
In this way, CR (carriage return) will inevitably appear,
which will affect the use of decodecode in the Ubuntu environment.
The repaired effect is as follows:
/ # ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
/ # ./scripts/decodecode < oops.file
[ 0.734345] Code: d0002881 912f9c21 94067e68 d2800001 (b900003f)
All code
========
0: d0002881 adrp x1, 0x512000
4: 912f9c21 add x1, x1, #0xbe7
8: 94067e68 bl 0x19f9a8
c: d2800001 mov x1, #0x0 // #0
10:* b900003f str wzr, [x1] <-- trapping instruction
Code starting with the faulting instruction
===========================================
0: b900003f str wzr, [x1]
