ip2k-elf doesn't build. The build process fails while building gcc. Specifically, __gcc_bcmp hits an ICE like so: /home/kazu/gnu/gcc/gcc-develop/gcc/gcc/libgcc2.c: In function $-1ער__gcc_bcmpעש: /home/kazu/gnu/gcc/gcc-develop/gcc/gcc/libgcc2.c:1797: error: insn does not satisfy its constraints: (insn 120 42 103 3 /home/kazu/gnu/gcc/gcc-develop/gcc/gcc/libgcc2.c:1793 (set (reg:HI 128 $80 [orig:280 D.1980 ] [280]) (minus:HI (reg:HI 136 $88 [orig:285 c1 ] [285]) (zero_extend:HI (reg/v:QI 128 $80 [orig:278 c2 ] [278])))) 48 {*subhi3_nonimm_zero_extend} (nil) (expr_list:REG_DEAD (reg:HI 136 $88 [orig:285 c1 ] [285]) (nil))) /home/kazu/gnu/gcc/gcc-develop/gcc/gcc/libgcc2.c:1797: internal compiler error: in copyprop_hardreg_forward_1, at regrename.c:1570 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions. Here is a testcase, derived from a preprocessed source. typedef unsigned int size_t; int __gcc_bcmp (const unsigned char *s1, const unsigned char *s2, size_t size) { while (size > 0) { const unsigned char c1 = *s1++, c2 = *s2++; if (c1 != c2) return c1 - c2; size--; } return 0; }
