13 : edgomez 512 # You can set/add options to CC and CFLAGS without editing this Makefile
14 :     # You have just to export an environment CC/CFLAGS variable before running
15 :     # make.

17 :     # Examples :
18 :     # $ export CC='gcc-3.1'
19 :     # $ export CFLAGS='-maccumulate-outgoing-args'

55 : edgomez 512 # General Optimization options

76 :     # CFLAGS += -pg
77 :     # Precise profiling + test coverage (-pg must be activated)
78 :     # Build the library twice and execute a program using the lib twice too
79 :     # First pass : Will create sourcefile.da files to keep branch statistics
80 :     # CFLAGS += -fprofile-arcs
81 :     # Second pass : Will create .bb and .bbg files suitable for coverage and
82 :     # branch probabilities during compilation
