+Embedded image support uses .incbin in inline assembly to include binary
|
|
|
68
|
+files. The file dependency is not spotted by ccache when deciding
|
|
|
69
|
+whether or not to rebuild embedded.o. This results in builds that
|
|
|
70
|
+contain an outdated version of the embedded image when ccache is used.
