*	Give cortexa8 TBB procedure a shorter file name.HEAD master	P. J. McDermott	2012-05-30	1	-383/+0
\|
*	Add "${BBL_GCCTGTOPTS}" to the final cross GCC.	P. J. McDermott	2012-04-22	1	-6/+7
\|
*	Fix placement of EGLIBC ports add-on.	P. J. McDermott	2012-04-22	1	-2/+1
\| \| \| \| \| \| \| \|	Occam's razor shows that copying the entire ports add-on over the libc sources is a bad idea compared to simply adding a link to the add-on in the libc source directory. See also: <http://www.eglibc.org/archives/patches/msg01137.html>.
*	Set the version of Linux-libre in Cortex-A8 TBB.	P. J. McDermott	2012-04-19	1	-8/+6
\|
*	Fix "invalid swi expression" error?	P. J. McDermott	2012-04-19	1	-5/+4
\| \| \| \| \| \| \| \| \| \| \| \| \|	Building EGLIBC with the static GCC would result in an error such as this: /tmp/[...].s: Assembler messages: /tmp/[...].s:168: Error: invalid swi expression /tmp/[...].s:168: Error: value of 983045 too large for field of 2 byt es at 170 Apparently, it makes no sense for GCC to generate Thumb code with the ARM Architecture Procedure Call Standard (AAPCS).
*	Add target-specific GCC options to cortexa8 TBB.	P. J. McDermott	2012-03-29	1	-2/+7
\|
*	Write a (non-working) cortexa8 TBB setup.	P. J. McDermott	2012-03-29	1	-0/+381
	EGLIBC fails to build: ../sysdeps/unix/syscall.S: Assembler messages: ../sysdeps/unix/syscall.S:28: Error: cannot represent SWI relocation in this object file format make[2]: * [/home/pj/bbl/sys.cortexa8/fsmnt/src/eglibc-build/misc/syscall.o] Error 1 make[2]: Leaving directory `/home/pj/bbl/sys.cortexa8/fsmnt/src/eglibc-2.15/libc/misc' make[1]: * [misc/subdir_lib] Error 2 make[1]: Leaving directory `/home/pj/bbl/sys.cortexa8/fsmnt/src/eglibc-2.15/libc' make: *** [all] Error 2 Apparently SWI (software interrupt) vector table relocation is only available in certain ARM cores (including Cortex-A8).
