--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
I always wondered if it is more efficient to have constant pools per function
in .text so we can do %rip relative loads with short displacement?
I suppose the assembler could even optimize things if there's the desired
constant somewhere near in the code itself... (in case data loads from icache
do not occur too much of a penalty). The assembler could also replace
.palign space before function start with (small) constant(s).
Nothing we can really do given x86 has no idea of instruction sizes.
