3# Tests for the special MAKE_PRINT_VAR_ON_ERROR variable, which prints the
4# values of selected variables on error.

6# XXX: As of 2020-10-23, the .ERROR_CMD variable is pointless in compat mode
7# since at the point where it is filled in PrintOnError, the first command in
8# gn->commands has been set to NULL already.  This leaves .ERROR_CMD an empty
9# list.

14# XXX: As of 2021-02-04, PrintOnError calls Var_Subst with SCOPE_GLOBAL, which
15# does not expand the node-local variables like .TARGET.  This results in the
16# double '${.TARGET}' in the output.
