     9 Subject: Crosstool sh4-linux-gcc-4.0.2-glibc-2.3.5 patches
    10 
    11 On sh[34]-linux, memset function does not work if 2nd argument is negative
    12 and 3rd argument is greater than 12.
    13 for example, memset(ptr, "\xda", 20) sets 0xff instead of 0xda.
    14  
    15 Attached patch fixes this problem.
    16  
    17 	* sysdeps/sh/memset.S (memset): Correct 2nd argument handling.
