+Subject: [PATCH] [llvm-windres] Pass user preprocessor arguments before the
+ input filename (#75389)
+
+If passing the windres option --preprocessor, the default arguments "-E
+-xc -DRC_INVOKED" aren't passed. If these are passed explicitly by the
+user via --preprocessor-arg instead, we need to make sure that "-xc" is
+passed before the input filename, as this compiler/preprocessor option
+only has an effect on input files that follow it.
+
+This fixes one of the issues with llvm-windres observed in
+https://github.com/msys2/MINGW-packages/pull/19157.

+Subject: [PATCH] [llvm-windres] Resolve the --preprocessor executable in $PATH
+ (#75390)
+
+The llvm::sys::ExecuteAndWait function doesn't resolve the file to be
+executed from $PATH - i.e. it is similar to execv(), not execvp().
+
+Due to this, specifying a --preprocessor argument to llvm-windres only
+worked if it specified an absolute path to the preprocessor executable.
+This was observed as one of the issues in
+https://github.com/msys2/MINGW-packages/pull/19157.
+
+Before d2fa6b694c2052cef1ddd507f6569bc84e3bbe35, this usage of
+--preprocessor seemed to work, because the first argument of Args[] was
+ignored and llvm-windres just executed the autodetected clang executable
+regardless.
+
+Also improve the error messages printed if preprocessing failed. (If the
+preprocessor executable was started but itself returned an error, we
+don't get any error string.)
