[LLVMdev] ARM Jump table pcrelative relaxation in clang / llc
Hi,
I have kept working on this and found the following (as llvm 3.5):
1) In the function MCObjectStreamer::EmitInstruction there is a check for
the instruction being relaxable or not:
if (!Assembler.getBackend().mayNeedRelaxation(Inst)) {
EmitInstToData(Inst, STI);
return;
}
At this stage, the instruction as been already selected to be ARM::ADR.

error in display function of the ARM package
Hi,
I get the following error message when trying to use the display
function on the ARM package:
> display(model)
Error in .Internal(round(x, digits)) : no internal function "round"
Looks like some kind of mismatch between the ARM package and some
others? Can I somehow get around it? I have learned to like the display
function to print model summaries.
Here is my sessionInfo():

[LLVMdev] ARM Jump table pcrelative relaxation in clang / llc
I have created a small ll file to reproduce the problem.
I used the intrinsic function llvm.arm.space to introduce space between the
beginning of the code and the jump table.
If the first argument of llvm.arm.space is higher than INT_MAX (
*2147483647)*, then the bug is hit. Lower or equal to that value, it
passes. It looks like a precision issue. Does this sound familiar to
someone?
