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

1063# Usage: unpack_pdv [file to unpack] [size of off_t]
1064# - you have to specify the off_t size ... i have no idea how to extract that

1066# the size of the off_t type (in bytes) on the machine that built the pdv
1067# archive. one way to determine this is by running the following commands:
1068# strings <pdv archive> | grep lseek
1069# strace -elseek <pdv archive>
1070# basically look for the first lseek command (we do the strings/grep because
1071# sometimes the function call is _llseek or something) and steal the 2nd
1072# parameter. here is an example:
1073# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1074# lseek
1075# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1076# lseek(3, -4, SEEK_END) = 2981250
