Although the NDK ABI for x86 doesn't include SSE4.1, it's needed for roundss/roundsd, and we've used that (via hand-written assembler) in the x86 libm since Android M. We've recently switched to using compiler builtins to generate the assembler instead, and without allowing the compiler to use SSE4.1, it can't (resulting in infinite recursion as these functions defer to themselves for an answer). Given that the x86 libm.so has required SSE4.1 for 8 years at this point without anyone noticing, let alone caring, let's just retain the status quo rather. (Despite the fact that this caused boot failures for cf_x86, I didn't notice when testing the 32-bit libm.so from a cf_x86_64 build because our x86-64 ABI *does* include SSE4.1, and the BoardConfig.mk for cf_x86_64 explicitly chooses "silvermont" as the 32-bit cpu variant, implicitly enabling SSE4.1.) Test: llvm-objdump -d on a cf_x86 build Change-Id: I9392d3699057fcca96677de52f8d36d377b1719a |
