[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: [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.
