X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=92f282988b4ce3967ee8399f7d1184ebfa04e48b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [SPARC64]: Fix quad-float multiply emulation. Something is wrong with the 3-multiply (vs. 4-multiply) optimized version of _FP_MUL_MEAT_2_*(), so just use the slower version which actually computes correct values.
