I think the following testcase is closer to my case:
int shouldbecall16(void);
int g(void) { shouldbecall16(); return 0; }
And in this case, I got (with or without -O2):
daddiu $sp,$sp,-16
sd $28,0($sp)
lui $28,%hi(%neg(%gp_rel(g)))
daddu $28,$28,$25
daddiu $28,$28,%lo(%neg(%gp_rel(g)))
ld $25,%call16(shouldbecall16)($28)
sd $31,8($sp)
.reloc 1f,R_MIPS_JALR,shouldbecall16
1: jalr $25
nop
Thank you for your time.
