20 # ecpu_check
21 # Usage:
22 #
23 # ecpu_check array_of_cpu_flags
24 #
25 # array_of_cpu_flags - An array of cpu flags to check against USE flags
26 #
27 # Checks user USE related cpu flags against /proc/cpuinfo. If user enables a
28 # cpu flag that is not supported in their processor flags, it will warn the
29 # user if CROSSCOMPILE is not set to 1 ( because cross compile users are
30 # obviously using different cpu flags than their own cpu ). Examples:
31 #
32 # CPU_FLAGS=(mmx mmx2 sse sse2)
33 # ecpu_check CPU_FLAGS

84 # This function generate linker scripts in /usr/lib for dynamic

87 # in some cases when linking dynamic, the .a in /usr/lib is used
88 # instead of the .so in /lib due to gcc/libtool tweaking ld's
89 # library search path. This cause many builds to fail.
90 # See bug #4411 for more info.
91 #
92 # To use, simply call:
93 #
94 # gen_usr_ldscript libfoo.so
95 #
96 # Note that you should in general use the unversioned name of
97 # the library, as ldconfig should usually update it correctly
98 # to point to the latest version of the library present.
