Alexey Kopytov 966d6d2fb0 Bug #48537: difference of index selection between rpm binary ... and .tar.gz, windows vs linux.. On Intel x86 machines index selection by the MySQL query optimizer could sometimes depend on the compiler version and optimization flags used to build the server binary. The problem was a result of a known issue with floating point calculations on x86: since internal FPU precision (80 bit) differs from precision used by programs (32-bit float or 64-bit double), the result of calculating a complex expression may depend on how FPU registers are allocated by the compiler and whether intermediate values are spilled from FPU to memory. In this particular case compiler versions and optimization flags had an effect on cost calculation when choosing the best index in best_access_path(). A possible solution to this problem which has already been implemented in mysql-trunk is to limit FPU internal precision to 64 bits. So the fix is a backport of the relevant code to 5.1 from mysql-trunk.		2010-05-29 22:16:45 +04:00
