Hi, Has anyone been building SH kernels with Dan's latest crosstool gcc? [alex@cambridge linux-2.6.8.1]$ sh4-unknown-linux-gnu-gcc --version sh4-unknown-linux-gnu-gcc (GCC) 3.3.3 20040126 (prerelease) Specifically the routine root_nfs_parse_addr() (in net/ipv4/ipconfig.c) would parse an invalid address. It seemed to skip out the initial loop early. I was a tad confused and started sprinkling printk's in the routine to see what the matter could be. Finally I had the loop like thus: while (octets < 4) { printk(KERN_ALERT "top: octets=%d, cp=%p, cq=%p\n", octets,cp,cq); while (*cp >= '0' && *cp <= '9') cp++; if (cp == cq || cp - cq > 3) break; if (*cp == '.' || octets == 3) octets++; if (octets < 4) cp++; cq = cp; printk(KERN_ALERT "bottom: octets=%d, cp=%p, cq=%p\n", octets,cp,cq); } And suddenly it worked! Very strange and my reason to be suspicious of the compiler. If anyone has any suggestions on how to proceed and generate a test case I would be glad to help diagnose wtf is going on. -- Alex, Kernel Hacker: http://www.bennee.com/~alex/ panic("floppy: Port bolixed."); 2.2.16 /usr/src/linux/include/asm-sparc/floppy.h ------ Want more information?
