Just a note: with e14f7abaf81d5d0aa7898570024286de8c188817 gas is not
emitting R_LARCH_RELAX for 2-operand la.tls.ie:
$ cat t.s
.globl _start
_start:
la.tls.ie $a0, foo
.section .tdata
foo: .word 114514
$ gas/as-new t.s -o t.o
$ binutils/objdump -dr t.o
t.o: file format elf64-loongarch
Disassembly of section .text:
0000000000000000 <_start>:
0: 1a000004 pcalau12i $a0, 0
0: R_LARCH_TLS_IE_PC_HI20 foo
4: 28c00084 ld.d $a0, $a0, 0
4: R_LARCH_TLS_IE_PC_LO12 foo
I guess this needs to be fixed too.
