--- Comment #5 from Yiting Wang <yitingwang16 at outlook dot com> ---
But if I remove the first line of test.c and change the default linker scripts
to
.sdata ALIGN(0x1000) :
{
__global_pointer$ = . + 0x800;
*(.srodata.cst16) *(.srodata.cst8) *(.srodata.cst4) *(.srodata.cst2)
*(.srodata .srodata.*)
*(.sdata .sdata.* .gnu.linkonce.s.*)
}
The sdata section is aligned at 0x1000 and this time gp relaxation works.
Disassembly of section .text:
