Subject: [PATCH v2 0/5] sim: Suppress warnings if built with Clang
Date: Sun, 25 Sep 2022 08:42:01 +0000 [thread overview]
Message-ID: <cover.1664095312.git.research_trasio@irq.a4lg.com> (raw)
In-Reply-To: <cover.1663073826.git.research_trasio@irq.a4lg.com>
Hello,
This is the version 2 patchset to suppress Clang compiler warnings
(causes a build failure due to default -Werror).
[Background]
When we build Binutils and GDB with Clang, it causes a build failure due to
warnings generated by Clang and the default -Werror configuration.
I finally managed to make ALL ARCHITECTURE ENABLED Binutils and GDB
-Werror-free on Clang 15.0.0 (note that this does not necessarily mean
warning-free) and this patchset is a part of it (common simulator part
except the printf-like functions).
Full Clang 15.0.0 -Werror-free branch is available at:
<https://github.com/a4lg/binutils-gdb/tree/clang-nowarn-dev>
[About this Patchset]
This patchset contains four five fixes to the files under sim{,/common}.
Each contains minor fixes to suppress Clang / GCC warnings.
Each change is detailed in the each patch.
[Changes: v1 -> v2]
- Commit messages are improved
- PATCH v1 1/4 is Moved to another patchset
- PATCH v1 2-4/4 -> PATCH v2 1-3/5
- New: Check known getopt definition on sim (PATCH v2 4/5)
This test is already performed on binutils, gas, gprof and ld and this
commit does the same to sim.
- New: Initialize pbb_br_* by default (PATCH v2 5/5)
It did not generate warnings on Clang but GCC creates some warnings
(although those are not reported as errors).
This is due to uninitialized pbb_br_* variables and this commit fixes
the issue by initializing them by a harmless value.
Thanks,
Tsukasa
