| * | util: Fix util_fast_pow/exp2/log2. | Brian | 2008-11-09 | 1 | -65/+47 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Use a lookup table for log2. - Compute (float) (1 << ipart) by tweaking with the exponent directly to avoid integer overflow and float conversion. - Also table negative exponents to avoid float division and branching. - Implement util_fast_exp as function of util_fast_exp2. -------- Cherry-picked from gallium-0.2: 8415d06d90a197e16554dab98d160334fd9f9f93 This fixes some pow() glitches seen in fslight.c, spectex.c, etc. Conflicts: src/gallium/auxiliary/util/u_math.h | ||||
