RISC-V: Support GNU indirect functions.
Generally, glibc dynamic linker should have two ways to deal with ifunc
- one is to handle the IRELATIVE relocations for the non-preemtive ifunc
symbols, the other is to handle the R_RISCV_32/64 and R_RISCV_JUMP_SLOT
relocations with the STT_IFUNC preemtive symbols. No matter which method
is used, both of them should get the resolved ifunc symbols at runtime.
Therefore, linker needs to generate the correct dynamic relocations for
ifunc to make sure the the dynamic linker works well. For now, there are
thirteen relocations are supported for ifunc in GNU ld,
* R_RISCV_CALL and R_RISCV_CALL_PLT:
The RISC-V compiler won't generate R_RISCV_JAL directly to jump to an
ifunc. Besides, we disable the relaxations for the relocation referenced
to ifunc, so just handling the R_RISCV_CALL and R_RISCV_CALL_PLT should be
enough. Linker should generate a .plt entry and a .got.plt entry for it,
and also needs to insert a dynamic IRELATIVE in the .got.plt enrty, or
insert a R_RISCV_JUMP_SLOT when generating shared library.
* R_RISCV_PCREL_HI20 and R_RISCV_PCREL_LO12_I/S:
LA/LLA pattern with local fPIC ifunc symbol, or any non-PIC ifunc symbol.
The PC-relative relocation. The current linker will deal with them in
the same way as R_RISCV_CALL_PLT.
* R_RISCV_GOT_HI20 and R_RISCV_PCREL_LO12_I/S:
LA pattern with global PIC ifunc symbol. Linker should insert a dynamic
IRELATIVE in the .got entry, or insert a R_RISCV_32/64 when generating
shared library.
* R_RISCV_32 and R_RISCV_64:
Store the ifunc symbol into the data section. Linker should insert a
dynamic IRELATIVE in the data section, or insert a R_RISCV_32/64 when
generating shared library.
* R_RISCV_HI20 and R_RISCV_LO12_I/S:
The LUI + ADDI/LW/SW patterns. The absolute access relocation. The
medlow model without the -fPIC compiler option should generate them.
The ld ifunc testsuites "Build pr23169a" and "Build pr23169d" need the
relocations, they are in the ld/testsuite/ld-ifunc/, and need compiler
support.
However, we also made some optimizations with reference to x86,
* If GOT and PLT relocations refer to the same ifunc symbol when generating
pie, then they can actually share a .got entry without creating two entries
to store the same value and relocation.
* If GOT, PLT and DATA relocations refer to the same ifunc symbol when
generating position dependency executable, then linker will fill the address
of .plt entry into the corresponding .got entry and data section, without
insert any dynamic relocations for the GOT and DATA relocations.
For the ifunc testcases, there are three types of them,
1. ifunc-reloc-*: Only check the single type of relocation refers to
ifunc symbol.
* ifunc-reloc-call: R_RISCV_CALL and R_RISCV_CALL_PLT.
* ifunc-reloc-data: R_RISCV_32 and R_RISCV_64.
* ifunc-reloc-got: R_RISCV_GOT_HI20 and R_RISCV_PCREL_LO_I/S.
* ifunc-reloc-pcrel: R_RISCV_PCREL_HI20 and R_RISCV_PCREL_LO_I/S.
2. ifunc-[nonplt|plt]-*: If we don't have PLT relocs, then don't need to
create the PLT and it's .plt entries.
* ifunc-nonplt: Combine R_RISCV_GOT_HI20 and R_RISCV_32/64.
* ifunc-plt: Combine all ifunc relocations.
3. ifunc-seperate-*: If we link the ifunc caller and resolver into the
same module (link the objects), then the results are the same as the
ifunc-reloc-* and ifunc-[noplt|plt]-* testcases. Consider the cases that
the ifunc callers and resolver are in the different modules, that is, we
compile the ifunc resolver to the shared library first, and then link it
with the ifunc callers. The output of ifunc callers should be the same as
the normal STT_FUNC cases, and the shared ifunc resolver should define the
symbols as STT_IFUNC.
The R_RISCV_PCREL_HI20 reloc is special. It should be linked and resolved
locally, so if the ifunc resolver is defined in other modules (other shared
libraries), then the R_RISCV_PCREL_HI20 is unresolvable, and linker should
issue an unresolvable reloc error.
