"Rounding: Valgrind does observe the 4 IEEE-mandated rounding modes (to nearest, to +infinity, to -infinity, to zero) for the following conversions: float to integer, integer to float where there is a possibility of loss of precision, and float-to-float rounding. For all other FP operations, only the IEEE default mode (round to nearest) is

supported."

RIP my attempts to run any RandomX using code under valgrind

hyc have you ever tried using valgrind with RandomX in monerod or anywhere else?

no, never tried it.

sech1 what are you trying to test?

Trying to run P2Pool with valgrind. It works only without RandomX

With RandomX, it just doesn't sync. It doesn't even spit out "invalid hash" errors

so you suspect memory corruption bugs somewhere?

maybe try with ElectricFence. but as I recall, there are no plain uses of heap allocations, everything is using mmap'd memory. so efence wouldn't find anything.

No, there is no memory corruption. Valgrind just doesn't support rounding modes (except for float <-> int conversions)

I wanted to try it to see what it finds. It works fine without RandomX (and it didn't find anything)
