A command like "cc -c -E" is tautological; the -c is ignored, when we explicitly specify that we want to preprocess only.
Since https://github.com/llvm/llvm-project/commit/6461e537815f7fa68cef06842505353cf5600e9c and https://github.com/llvm/llvm-project/pull/98607, Clang now warns about the unused "-c" argument in this case. We already did omit the "-c" argument when preprocessing (with cl.exe) for armasm, but do this for other cases as well. --- gas-preprocessor.pl | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/gas-preprocessor.pl b/gas-preprocessor.pl index 19b0131..aa3abc0 100755 --- a/gas-preprocessor.pl +++ b/gas-preprocessor.pl @@ -155,6 +155,8 @@ while ($index < $#preprocess_c_cmd) { $index++; } +@preprocess_c_cmd = grep ! /^-c$/, @preprocess_c_cmd; + my $tempfile; if ($as_type ne "armasm") { @gcc_cmd = map { /\.[csS]$/ ? qw(-x assembler -) : $_ } @gcc_cmd; @@ -163,7 +165,6 @@ if ($as_type ne "armasm") { # Clang warns about unused -D parameters when invoked with "-x assembler". @gcc_cmd = grep ! /^-D/, @gcc_cmd; } else { - @preprocess_c_cmd = grep ! /^-c$/, @preprocess_c_cmd; @preprocess_c_cmd = grep ! /^-m/, @preprocess_c_cmd; @preprocess_c_cmd = grep ! /^-G/, @preprocess_c_cmd; -- 2.34.1 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
