Auto dependency generation fails to depend on Hax system headers #1

Closed mkoval closed 14 years ago

mkoval commented 14 years ago

System headers (i.e. #include <foo.h>) are not added to the dependency files generated by GCC. This forces a make rebuild for all programs if any of the system headers are modified (e.g. hax.h, stdint.h...).

This behavior is a result of passing gcc the -MM flag when generating the dependency files, but there are numerous preprocessor errors if the flag is changed to -M.

Note that this problem only occurs with the vex_pic architecture and is fixed in the vex_cortex architecture.
