How to implement load/store for vector predicate register
...pr) for vector predicate registers in backend.
Although there is no direct instruction to move vpr to vr or to move vr to vpr, there is a method to work around this. And we have load/store instructions for vr.
move vpr to vr for v32i16 (from vpr0 to vr1):
1 vclr vr0 // clear vr0
2 ldi r5, 0x00010001 // load immediate (compare bit mask for v32i16) to scalar register r5
3 movr2vr.dup vr2, r5 // duplicate content in r5 into vr2,
4 vadd.t.s16 vr1, vr0, vr2, vpr0 //vector add if element compare bit is set, element type is 16 bit signed integer, now we have moved compare...

Incorrect Cortex-R4/R4F/R5 ProcessorModel in ARM.td
In ARM.td, I see that the ProcessorModel for cortex-r4, cortex-r4f, and cortex-r5 (as well as r7 and r8) is based on "CortexA8Model", which seems incorrect. When this was added in 2015, there were also comments associated with this configuration, such as "// FIXME: R5 has currently the same ProcessorModel as A8" (later removed). The processor model for Cort...

[LLVMdev] How can I remove these redundant copy between registers?
Hi,
I've been working on a Blackfin backend (llvm-3.6.0) based on the previous
one that was removed in llvm-3.1.
llc generates codes like this:
29 p1 = r2;
30 r5 = [p1];
31 p1 = r2;
32 r6 = [p1 + 4];
33 r5 = r6 + r5;
34 r6 = [p0 + -4];
35 r5 *= r6;
36 p1 = r2;
37 r6 = [p1 + 8];
38 p1 = r2;
p1 and r2 are in different register classes.
A p* register can be used for load/stroe values from memory while a r*
register can...

[LLVMdev] Mapping registers into memory address
...de for Android's Dalvik VM.
I translated some DEX bytecode to LLVM IR, and now I wnat to translate
these IR into ARM assembly by using llc.
But there are some ABI problems (Register mapping) should be solved.
Dalvik VM stores virtual register in the fixed memory address.
For example,
v0 -> [r5,#0]
v1 -> [r5,#4]
v2 -> [r5,#8]
v3 -> [r5,#12]
....
v100 -> [r5,#400]
So I want to know how can I generate such register allocation?
(e.g load v3 from [r5,#12] and store v2 into [r5,#8])
I have got the approach for reserving r5, but load/store problem not yet
Is there any related info...
