8 EGLIBC (Embedded GLIBC) is a variant of the standard GNU GLIBC
9 that is designed to work well on embedded systems. EGLIBC strives
10 to be source and binary compatible with GLIBC. Its goals include
11 a reduced footprint, configurable components, and improved
12 cross-compilation support. EGLIBC also includes some embedded ports
13 (such as e500/spe) that are normally separate add-ons of GLIBC.

74 Enter the revision of trunk you want to use.
77 A revision argument can be one of:
78 NUMBER revision number
79 '{' DATE '}' revision at start of the date (*)
80 'HEAD' latest in repository

91 By default, the eglibc download will be an export of the subversion
92 repository. If you say 'y' here, then the repository will instead be
93 checked-out, so that you can update it later.
95 Note that crosstool-NG will *not* update your working copy, you will
96 have to do that yourself.
98 config EGLIBC_OPT_SIZE
100 prompt "optimize eglibc for size (-Os)"
102 Optimize eglibc for size using -Os instead of -O2. This will make eglibc
103 smaller but may make it slower.

111 library. The configuration file options are described in detail in the
112 option-groups.def file in the eglibc source directory.
