TODO:
|
|
* gpr0 allocation
|
|
* implement do-loop -> bdnz transform
|
|
* implement powerpc-64 for darwin
|
|
* use stfiwx in float->int
|
|
* be able to combine sequences like the following into 2 instructions:
|
|
lis r2, ha16(l2__ZTV4Cell)
|
|
la r2, lo16(l2__ZTV4Cell)(r2)
|
|
addi r2, r2, 8
|
|
|
|
* Support 'update' load/store instructions. These are cracked on the G5, but
|
|
are still a codesize win.
|
|
|
|
* should hint to the branch select pass that it doesn't need to print the
|
|
second unconditional branch, so we don't end up with things like:
|
|
b .LBBl42__2E_expand_function_8_674 ; loopentry.24
