Assertion failure compiling code calling log10f

[maleadt]

Using a debug build of NEO v24.5.28454 and IGC v1.0.15985:

; ModuleID = '<llvm-reduce tmp module>'
target triple = "spir64-unknown-unknown"

declare float @_Z5log10f(float)

define spir_kernel void @kernel() {
  %v8 = load float, float addrspace(1)* null, align 4
  %v9 = call float @_Z5log10f(float %v8)
  store float %v9, float addrspace(1)* null, align 4
  ret void
}

Hi @maleadt for which platform was this issue reported?

[maleadt]

64-bit Linux with an Intel TigerLake-LP GT2 from a NUC11PAHi7 (i7-1165G7).
