<div>
<pre>In current version of llvm-as, LA macro is incorrectly expanded when in PIC
mode.
Real life example from Chromium source, sandbox/linux/seccomp-bpf/syscall.cc:
la $v0, 2f
in PIC mode is expanded to
lui v0,0x0
addiu v0,v0,0
instead of something like:
lw v0,0(gp)
addiu v0,v0,96
This issue is a reference for future work.</pre>
