rev 3362 : 7174532: jdk/test/java/lang/Math/ failing on x86
Summary: increase precision on x86 for the steps of the computation of exp and pow.

*** 2393,2402 **** --- 2393,2404 ---- // compute pow(x,y) and exp(x) with x86 instructions. Don't cover // all corner cases and may result in NaN and require fallback to a // runtime call. void fast_pow(); void fast_exp(); + void increase_precision(); + void restore_precision(); // computes exp(x). Fallback to runtime call included. void exp_with_fallback(int num_fpu_regs_in_use) { pow_or_exp(true, num_fpu_regs_in_use); } // computes pow(x,y). Fallback to runtime call included. void pow_with_fallback(int num_fpu_regs_in_use) { pow_or_exp(false, num_fpu_regs_in_use); }
