+Date: Sat, 16 Nov 2024 05:57:40 +0000
+Subject: [PATCH] [Clang][Driver] report unsupported option error regardless of
+ argument order
+
+This change updates clang to report unsupported option errors regardless
+of the command line argument order.
+
+When clang with a source file and without `-c` it will both compile and
+link. When an unsupported option is also part of the command line clang
+should generated an error. However, if the source file name comes before
+an object file, eg: `-lc`, the error is ignored.
+
+```
+$ clang --target=x86_64 -lc hello.c -mhtm
+clang: error: unsupported option '-mhtm' for target 'x86_64'
+$ echo $?
+1
+```
+
+but if `-lc` comes after `hello.c` the error is dropped
+
+```
