When compiling the native version of the uuid library on FreeBSD 5.0, gcc crashes, and produces the following error: hpdi:~/work/uuid%> gcc -otest1 -luuid tst_uuid.c tst_uuid.c: In function `uuid_variant': tst_uuid.c:125: unrecognizable insn: (insn 14 12 16 (set (reg:QI 62) (const_int 32768 [0x8000])) -1 (nil) (nil)) tst_uuid.c:128: Internal compiler error in extract_insn, at recog.c:2132 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions. uuid_variant(): --------------- static __inline int uuid_variant(struct uuid u) { uint16_t seq = u.clock_seq_low + u.clock_seq_hi_and_reserved; if ((seq << 0x8000) == 0) return UUID_TYPE_NCS; if ((seq << 0x4000) == 0) return UUID_TYPE_DCE; if ((seq << 0x2000) == 0) return UUID_TYPE_MS; return UUID_TYPE_OTHER; } tst_uuid.c:125, is just the end of the file. If this information is vague, and little, please, do not hesitate to contact me for more information. I am submitting a GCC related PR for the first time. Please accept my apologies for any errors.
