Some assemblers (GNU as for LoongArch) generates relocations for leb128

The cost of lo_sum rtx for addi.d instruction my be a very big number if
computed by common function. It may cause some symbols saving to stack and
loading from stack if there no enough registers during loop optimization.

Thanks, I try to send a new version patch next week.

Hi,
Whether to add an option to control the generation of R_LARCH_RELAX,
similar to as -mrelax/-mno-relax.

In Binutils we need to make IE to LE relaxation only allowed when there
is an R_LARCH_RELAX after R_LARCH_TLE_IE_PC_{HI20,LO12} so an invalid
"partial" r
Hi,
Thanks, this patch is LGTM.

There are already -mrelax and -mno-relax, they can be checked
Add support for TLS descriptors on normal code model and extreme code model.
Normal code model instruction sequence:

-mexplicit-relocs:
pcalau12i $r4,%desc_pc_hi20(s)
addi.d $r4,$r4,%desc_pc_lo12(s)
