# You can define VFLAGS on the command line to add flags to the vala compiler.
# Some useful ones:
#
#  -g        annotate the output C with #line directives so that backtraces
#            from gdb, sanitisers and valgrind will list Vala source locations
#
#  -X -g -X -O0    compile the output C for sensible debugging
#
#  -X -fsanitize=address    link the output program against Address Sanitizer
#
#  --save-temps    don't automatically delete the C files after compiling
#
#  -D GC_STATS     print statistics every time the garbage collector runs
#
#  -D GC_DEBUG     print full diagnostics from the garbage collector
#
#  -D GC_ALWAYS    make the garbage collector run at every opportunity
#                  (good for making occasional GC errors show up sooner)
