[LLVMdev] Generate data16 assembly instruction for TLS with PIC
Hi all,
System: x86-64 ubuntu 11.04
LLVM: 3.0
gcc: 4.5.2
I declare a thread_local global variable and access it in a function in
llvm IR.
for example,
@my_value = linkonce thread_local global %dummy* null
define void @test1() {
entry:
%load_my_value = load %dummy** @my_value
....
}
After that, I use the following command:
bash$ llc -relocation-model=pic test.ll
And I have test.s

[LLVMdev] LLVMdev Digest, Vol 98, Issue 33
...this issue with the X86 backend. And, unfortunately, searching
