Martin Storsjö	aad0e26f93	checkasm: aacpsdsp: Tolerate extra intermediate precision in stereo_interpolate ... The stereo_interpolate functions add h_step to the values h BUF_SIZE times. Within the stereo_interpolate C functions, the values h (h0-h3, h00-h13) are declared as local float variables, but the compiler is free to keep them in a register with extra precision. If the accumulation is rounded to 32 bit float precision after each step, the less significant bits of h_step end up ignored and the sum can deviate, affecting the end result more than the currently set EPS. By clearing the log2(BUF_SIZE) lower bits of h_step, we make sure that the accumulation shouldn't differ significantly, regardless of any extra precision in the accmulating register/variable. This fixes the aacpsdsp checkasm test when built with clang for mingw/x86_32. Signed-off-by: Martin Storsjö <martin@martin.st>	2019-12-18 15:15:29 +02:00
