[LLVMdev] fmac generation for cortex-a9

[Sebastien DELDON-GNB]

Hi all,


I've a .ll code that use double precision fmul/fadd or fmul/fsub. When I compile it using llc -mcpu=cortex-a9 I couldn't get vmla/vmls generated even using -fp-contract=fast, but when I use option -mtriple=armv7-eabi instead of -mcpu=cortex-a9 fused mac are generated. Can someone explain me why  ?

Thanks for your answers
Seb
