From 69736cd828b76da6ad8257e96dd44bc0659b487d Mon Sep 17 00:00:00 2001 From: Elizabeth Figura Date: Mon, 25 Aug 2025 18:10:18 -0500 Subject: [PATCH] ltmain.in: Pass through all warning flags to the linker. When link-time optimization (LTO) is used, some warnings are reported while linking, and the flags must be passed to the linker to enable or disable them. -W* also catches -Wl,* and -Wa,*, but the former is already accounted for in an earlier switch case, and the latter is already passed through. * build-aux/ltmain.in: Pass through all warning flags to the linker. --- build-aux/ltmain.in | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/build-aux/ltmain.in b/build-aux/ltmain.in index 294ed43c3..0f2c81f8b 100644 --- a/build-aux/ltmain.in +++ b/build-aux/ltmain.in @@ -5664,7 +5664,7 @@ func_mode_link () # --unwindlib=* select unwinder library with clang # -f{file|debug|macro|profile}-prefix-map=* needed for lto linking # -Wa,* Pass flags directly to the assembler - # -Werror, -Werror=* Report (specified) warnings as errors + # -W* Warnings, needed for lto -64|-mips[0-9]|-r[0-9][0-9]*|-xarch=*|-xtarget=*|+DA*|+DD*|-q*|-m*| \ -t[45]*|-txscale*|-p|-pg|--coverage|-fprofile-*|-F*|@*|-tp=*|--sysroot=*|--target=*| \ -O*|-g*|-flto*|-fwhopr*|-fuse-linker-plugin|-fstack-protector*|-no-canonical-prefixes| \ @@ -5672,7 +5672,7 @@ func_mode_link () -specs=*|-fsanitize=*|-fno-sanitize*|-shared-libsan|-static-libsan| \ -ffile-prefix-map=*|-fdebug-prefix-map=*|-fmacro-prefix-map=*|-fprofile-prefix-map=*| \ -fdiagnostics-color*|-frecord-gcc-switches| \ - -fuse-ld=*|-static-*|-fcilkplus|-Wa,*|-Werror|-Werror=*) + -fuse-ld=*|-static-*|-fcilkplus|-W*) func_quote_arg pretty "$arg" arg=$func_quote_arg_result func_append compile_command " $arg" -- 2.47.3
