I MOSTLY 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 (simulator: printf-like functions). - It still requires -Wno-implicit-function-declaration on the LatticeMicro32 and M32R simulators. Except them, most of Binutils / GDB components can be built with Clang by default with my tree. - I noticed that the assembler is not tested enough (because just with --enable-targets=all, it builds only host assembler). Full Clang 15.0.0 -Werror-free branch in development is available at: Tested configuration: - Ubuntu 22.04.1 LTS (x86_64) - LLVM / Clang 15.0.0 (built from source) - Configuration examples: $srcdir/configure \ --enable-targets=all \ --enable-multilib --enable-ld --enable-gold --enable-nls \ CC=clang CXX=clang++ CCLD=clang CXXLD=clang++ \ CFLAGS=' -O2 -g -Wno-implicit-function-declaration' \ CXXFLAGS='-O2 -g -Wno-implicit-function-declaration' $srcdir/configure \ --target=riscv64-unknown-linux-gnu \ --enable-multilib --enable-ld --enable-gold --enable-nls \ CC=clang CXX=clang++ CCLD=clang CXXLD=clang++ \ CFLAGS='-O2 -g' CXXFLAGS='-O2 -g' [About this Patchset] Clang generates a warning if the format string of a printf-like function is not a literal ("-Wformat-nonliteral"). On the default configuration, it causes a build failure (unless "--disable-werror" is specified). To avoid warnings on the printf-like wrapper, it requires proper __attribute__((format)) and we have ATTRIBUTE_PRINTF macro for this reason. This patchset adds ATTRIBUTE_PRINTF to all functions that require ATTRIBUTE_PRINTF macro. [Changes: v1 -> v2] - We only append ATTRIBUTE_PRINTF at function declarations, not definitions (based on the feedback by Andrew Burgess). - Fixed indents - Removed ChangeLog from commit messages (based on the feedback [to another patchset by me] by Bruno Larsen).
