[sh4] Introduce const pools in LLINT.
https://bugs.webkit.org/show_bug.cgi?id=122746
Patch by Julien Brianceau <jbriance@cisco.com> on 2013-10-15
Reviewed by Michael Saboff.
In current implementation of LLINT for sh4, immediate values outside range -128..127 are
loaded this way:
mov.l .label, rx
bra out
nop
.balign 4
.label: .long immvalue
out:
This change introduces const pools for sh4 implementation to avoid lots of useless branches
and reduce code size. It also removes lines of dirty code, like jmpf and callf.
* offlineasm/instructions.rb: Remove jmpf and callf sh4 specific instructions.
* offlineasm/sh4.rb:
