Zhang Xiianyi	7b410b7f0e	Fixed #58 zdot SEGFAULT bug with GCC-4.6. Thank Mr. John for this patch. In i386 calling convention, the caller put the address of return value of zdot into the first hidden parameter. Thus, the callee should delete this address before return. Actually, I have fixed the same bug on x86/zdot_sse2.S (issue #32). However, that is not a good implementation which uses 3 instructions. Mr. John told me used "ret $0x4" to skip the first hidden address (4 bytes).	14 years ago
