yann@402: Subject: Crosstool sh4-linux-gcc-4.0.2-glibc-2.3.5 patches
yann@402: 
yann@402: On sh[34]-linux, memset function does not work if 2nd argument is negative
yann@402: and 3rd argument is greater than 12.
yann@402: for example, memset(ptr, "\xda", 20) sets 0xff instead of 0xda.
yann@402:  
yann@402: Attached patch fixes this problem.
yann@402:  
yann@402: 	* sysdeps/sh/memset.S (memset): Correct 2nd argument handling.
