RISC-V: Added ld testcase for pcgp relaxation. Consider the the pcgp-relax-02 testcase, .text .globl _start _start: .L1: auipc a0, %pcrel_hi(data_a) .L2: auipc a1, %pcrel_hi(data_b) addi a0, a0, %pcrel_lo(.L1) addi a1, a1, %pcrel_lo(.L2) .data .word 0x0 .globl data_a data_a: .word 0x1 .section .rodata .globl data_b data_b: .word 0x2 If the first auipc is deleted, but we are still building the pcgp table (connect the high and low pcrel relocations), then there is an aliasing issue that we need some way to disambiguate which of the two symbols we are targeting. Therefore, Palmer thought of a way to use R_RISCV_DELETE to split this into two phases, so we could resolve the addresses before creating the ambiguities. This patch just add the ld testcase for the above case, in case we have changed something but break this. ld/ * testsuite/ld-riscv-elf/ld-riscv-elf.exp: Renamed pcgp-relax to pcgp-relax-01, and added pcgp-relax-02. * testsuite/ld-riscv-elf/pcgp-relax-01.d: Renmaed from pcgp-relax. * testsuite/ld-riscv-elf/pcgp-relax-01.s: Likewise. * testsuite/ld-riscv-elf/pcgp-relax-02.d: New testcase. * testsuite/ld-riscv-elf/pcgp-relax-02.s: Likewise. 2021-10-22 11:32:46 +08:00			`#source: pcgp-relax-02.s`
