- Subject: RTX costs
Hi all,
After reading the internal docs about rtx_costs I am left wondering what
they exactly are estimating.
- Are they estimating in the beginning of expand how many insns will be
generated from a particular insn until the assembler is generated?
- or Are they estimating how many assembler instructions will be
generated for a particular insn?
- or something else?
If someone could clear this up, I would be happy. :)
Thanks,
Paulo Matos
