Hi,
I noticed gcc predicts huge sizes for asm statements on ix86. This is
due to define_asm_attributes in i386.md, where the length *per single
instruction* in the asm is set to 128. That doesn't look realistic to
me. Is there a good reason for this large value? Or should something
like the patch below be tested? (I choose 16 but I don't know if there
are larger insns for x86 - I assume you do ;-)
Ciao!
Steven
