[llvm-commits] [PATCH] MCAssembler Performance: Lazy invalidation

[David Meyer]

Rafael,

It may cause more layout passes, but each layout pass is cheaper. (since the
layout is computed at most once per pass).

Another data point:

For my largest organic .s file (gcc.s, 514476 instructions), the output
object is 336 bytes larger out of 2.3 MB total. There's a slight improvement
in assemble time, 2.35 sec vs 2.48 sec.

How about adding a FIXME? Maybe add a pointer to PR8467.


New patch attached.
(Note that I don't have repository access)

Thanks,
David
