Message-ID: <20090209153449.11445.qmail@sourceware.org> (raw)

CVSROOT:	/cvs/ecos
Module name:	ecos
Changes by:	nickg@sourceware.org	2009-02-09 15:34:49

Modified files:
	packages/hal/arm/arch/current: ChangeLog 
	packages/hal/arm/arch/current/src: vectors.S 

Log message:
	* src/vectors.S (start): The loop to initialize BSS was using a
	BLS to terminate. This caused an extra zero to be stored beyond
	the end of __bss_end. Usually this is benign, but when __bss_end
	is at the very top of RAM, and the hardware generates an exception
	for illegal accesses, this can crash the program before it even
	starts. The fix is to use a BLT instructions which will terminate
	the loop 1 word earlier.
